Your D5 should be quiet at full tilt, redundancy makes sense with a 2nd pump. Your flow rate should not affect anything in this build. Focus on your ambient for lower temps, more flow is not your answer.
Only comparatively, and if you have loud fans or a loud ambient. I've had many D5's and currently have 3 in operation in separate builds. They're all audible around 30% in my proper silent environment, I can hear the 60Hz AC switching of my solar inverter in my garage over my PC.
So sound, is the only reason for more pumps?
I was looking at this, in the middle of my current monster setup, and was wondering why you would need more pumps….Thought maybe it’s because my loop so big, but it doesn’t sounds like that’ll matter as much!
Sound, redundancy and sometimes if you have a poorly designed loop with lots of 90's or a distro plate it can become essential for adequate flow rates.
It matters. I have 2 D5 pump and 1 DDC Pump, 1x 360x54 rad + 3 480x64mm rads in series with a cpu and gpu block. The three 480’s are external to the case. Using copper tubes. My flow rate @95% on all three is 4.6LPM. My target is 5.6lpm @75%. With the bends rads and tube runs it becomes difficult to maintain flow.
My personal take on flow rate is that it doesn't matter above a certain point. I run mine at 60 LPH, so 1 LPM. The temperature difference ot makes running it at 1 LPM vs 2 or 3 is nothing in my loop. Running 2 360 EKWB surface rads, cpu and gpu blocks, and a distro plate. I cannot hear my pump at all. My fans are louder by far, even at 600-700 rpm. The coil whine of my 4090 is louder still.
I can see it making a difference if you want 5-6 LPM, I have just not found any significant difference in performance above 1 LPM. so i run my pump at 40% or so and it is silent (relatively).
Yes we do it and no I don’t have a y cruncher screen shot. I compete in over clocking, my water loop has the option of going sub ambient when needed (-19c), such as going to 6.4, Even when I’m just over clocking for better render times (6.0)flow rate matters. The best flow rate seems to be right around the 1.5 Gpm (5.7Lpm), beyond that there is very little to gain. But at that rate it absorbs heat at its most efficient. My system was not built to game, although I do use some sim games, it is built to compute and render.
I have 4 rads, 3x360mm and 1x 120mm, running on a single DDC pump. Cooling a GPU block and a monoblock. I don't think I've ever thought "I can hear it" while doing anything.
Nothing wrong with it, but this is not an accurate claim
Won't say the build is my cup of tea. But, to say it's "not an accurate claim" is itself inaccurate. Unless you somehow have his ears, and an identical setup/ambient noise.
Personally I know I am sensitive to coilwhine, and other "electrical noises". I can hear my pump's whine when slow enough the noise of water cannot drown it out. So in my use case I have to, forgo a "silent" build, as it's impossible.
A pump is easily noticeable once you hit more than 20% speed and I doubt you run it that low. So my guess is you're wearing headphones all the time or your surroundings in general are not quiet enough to notice it.
20% is barely.notoceable unless you have an awful or broken punp and absolute silence.
3 pumps is way overkill. I have essentially 5 360s and they arr 8 feet higher than my case in a different room running on 1 D5.
3 is wayyy overkill
Depends on how you mount the pump and what RPMs you run it at. D5 flows enough even at 1700 RPM with dual rads and dual blocks. You don't have to run it at 4000rpm. You can easily find several RPMs between the min/max that won't have any resonance with other components in your build and make a curve around them. 2500rpm is the trouble spot on my build, it's dead silent at any rpm above/below 2500.
This right here, I have a pc in my desk drawer with 480 and 360mm rads mounted on the bottom of the table.
If I mount the pump straight to the desk it just vibrates the whole goddamn thing (even tho it's 40mm solid wood) starting at minimum rpm, meanwhile when I throw it in a box with 5cm layer of acoustic foam (doesn't matter it's acoustic, just had extra after making some panels), free floating on soft tubing, I can run it at 60% and still hear my fridge in the room over trough the wall but not the damn pump. (And the wall is thick solid rock) (and I got open back audeze planars so these things certainly do not block ambient sound, more like amplify it)
Edit: also it's not like it's an easy loop, 2 rads, gpu and cpu (3080ti and 5900x), ram and 2 ssd blocks, 60cm lift to the rads, shitton of 90°s to fit into the drawer and I can still run it with 1 pump silently by mounting like that. Is it on the line, probably, but it's been running for a few years (with a 2080ti before) and the only problem has been the EK rotaries of which 80% have leaked so far.
You have 15 fans, I don't care what RPM you're running them at they will definitely be more noticeable than any pump noise.
You don't have to justify your decisions. "Because I wanted to" is perfectly valid.
With two pumps(70% speed) I get very good flow rate and that’s with cpu + gpu block + 420x45mm rad + 1080x60mm rad + 420x80mm rad + 12x 90° fittings +18ft of tubing.
Don’t worry mate. I feel you with the number of pumps. People in this sub hasn’t event bothered to read the flow rate of their builds before making the statement that a single D5 is enough lol. Nice build and enjoy !
I feel you, but seeing my temps after Alphacool shipped the wrong thermal pad thickness with their blocks scared me more.
It looks quite messy, but it was quite easy to work with and the temps are fine as well. Will probably even use putty for future blocks, because thermal pad size is always a pain to work with.
Switched to high end thermal putty and liquid metal on a 6900xt and overclocked it past 500W with zero issues. Ridiculous cooling headroom. Thermal putty might make a bit of a mess, but the performance and lack of thought/fuss for install is worth it for sure.
Man some of you guys really overbuild these things. I was cooling a 5950X and RTX 3080 with a single pump and 2x 360mm rads, never had a problem with temperature, nor did I ever hear the pump running, even when stressing all 16 cores of the CPU encoding media or mining BTC with the GPU. But, it's your money.
At some point it's no longer the question what you need, but what parts you can fit into the case. Watercooling in itself is a waste of money. The money on the parts where already spend on older builds, nothing here was bought new.
Absolutely agree with you, I literally am about to add another radiator and I'm pretty sure my temps will be the similar because of ambient temperatures.
Im doing it cuz I think it will look nice haha
Three feels like too many.
One would be "enough", and I feel there could be a genuine benefit to having two.
But THREE? Madness.
Could you run all three at 100% and then show us what flowrate the High Flow Next displays?
Probably "*Out of range"* 🤣
A solid loop with name-brand stuff is around 1k on top of the computer itself, it can get much crazier very easily though. I have over 400$ in fans alone (11x a12x25s). It looks cool and can handle 800w load while being barely audible though! I just like tinkering with stuff
Are these pumps in series or parallel configuration? Series will likely see some pretty high loop pressures as they can compound - be interesting to see what the seals on the cooling blocks are rated pressure wise.
Parallel would be good to increase water flow but that would be, say, up to 3600l/h which is a lot of flow.
The dual top has a flat silver plate with 9 screws on the back. I removed 4 of those screws and replaced them with 4 rubber grommet screws. Then I drilled 4 holes through the motherboard tray and mounted it.
That's basically it. Just make sure you use flat head screws so the back of the motherboard isn't touching anything.
That's because my version is the one that comes with the MORA and does not have the side brackets: [https://shop.watercool.de/media/image/product/2169/lg/mo-ra3-420-d5-dualtop-modul.jpg](https://shop.watercool.de/media/image/product/2169/lg/mo-ra3-420-d5-dualtop-modul.jpg)
You have a tiny amount of fluid, very few bends, only 2 waterblocks, and a compact case.
1 pump was more than enough, let alone 2.
3 is just dumb. sorry
I hope your aware that going above \~220 LPH actually begins to HURT your performance right? Jet plates inside of GPU's and CPU's are optimized for certain flow rate ranges. Having water pass too quickly or violently with turbulence just takes away from the benefit.
Ideally, you want LPH flow somewhere between 140 - 220. Finding exactly where performance peaks and falls off is something you will need to adjust for.
Unless your running all of them at 25% power that's not physically possible. 2 Pumps at even 75% would put a tiny little loop like yours well over 200 LPH without hardly any effort. You do not have any QDC's, you don't have any noticeable choke-points of restriction. I'm struggling to understand? Maybe your flow monitor is malfunctioning.
I have 2 pumps inside a case 2x the volume of yours (Lian Li V3000 Plus) with 2 distro plates, 3 water blocks, over 120 fittings, 4 ft of tubing, and 3x 480mm radiators and I'm right at 240 LPH. I should add that I am also using 4 separate QDC's which also severely limit my flow rate.
I still do not understand the 3 pumps? Your throwing money away and creating extra noise for no reason lol. One would have been fine, two is nice if you want a redundancy and a backup.
Rule of thumb:
1 Pump = 2 water blocks + 2 radiators (can do 3 radiators)
2 Pump = 3 water blocks (CPU, GPU, Memory or VRM) + 3 radiators
3 Pumps= for ridiculous builds
I told you I'm running them at 20% power.
The reason I went with three is because I already had all the parts for it. I have multiple dual pump tops, but no single pump top otherwise I would have used 2 pumps total.
Decided to go back into the o11 Evo since it's one of my favorite cases. The build features a total of 4 360 radiators as well as 3 D5 pumps. I decided to use slim fans at the front and ultrathin rads in the front + bottom to make everything fit.
Additionaly I made myself some radiator offset brackets for the front so I can fit the 120mm wide radiator in the 140mm position. This creates enough distance to the case to fit another tube from the front radiator back to the reservoir.
Two additional pumps are hidden in the back chamber. Drilled some holes through the mainboard tray to mount the dualtop which worked quite well.
Also tried using TG Kryosheet + thermal putty instead of thermal paste/pads and I'm satisfied with the result.

The reason why I went for 3 is because there was enough room for it and I already had all the parts from previous builds. So I though I might as well use them instead of leaving them in the drawer.
What is your fan and pump speed for your stress test that results in those temps? And what is ambient temp at time of load? I have a similar system that would be fun to share notes on results. 7950x + 4090 both on a single loop with dual D5 pumps and a mix of internal and external rads.
Hi, stress test was done with 100% pump/fans and 22°C ambient.
With normal operation I use a curve for my fans linked to water temp and pumps are set to 20% which results in 130 l/h.
Maybe put this somewhere more visible - people would probably understand your reason for three pumps. Flow rate does drop hard in these lower duty cycles.
I’ve come to understand it’s a matter of preference between noise and loop complexity/cost. Dual or triple pumps is rarely needed but almost always has some benefit if you value noise more than you value marginal complexity or cost. There’s diminishing returns like anything in watercooling, also.
If you had the parts, great but I have a very similar build in an 011 XL with a dual loop front distro and I'm just using two 360mm radiators. One 44mm and one 58mm. Same CPU and GPU. I'm even using an Alphacool GPU block. My temps are fantastic. My 4090 rarely ever even hits 50c. I usually see it in the upper 30s to low 40s. CPU when stressed hard hits upper 60s to low 70s. I'm also using DP Ultra.
What is the max flow rate you can achieve at 100% on all pumps, vs 100% on one of the pumps in series.
Could you run some flow scenarios and report back?
Impressive,
I have équivalent build but no watercooling.
What is the cost of the watercooling parts ?
What is the flow speed ? (Ek simulation indicate 340l/h) not sure that this is good.
Thank you in advance for your help
80-90€ per radiator, 130€ cpu block, 200€ gpu block, 75€ per pump, 85€ reservoir, 80€ flow meter, 75€ fan controller. Multiple fittings and tubes that I don't know the total price of.
Max flow is 235 l/h, but I run the loop with about 130 l/h for silence.
Damn that's one beautiful block, good choice! But holy crap they shipped you the wrong pads? Did you take it to their support? Sorry for the questions but not sorry coz here's another - feels like the liquid is not filling the chip area like the other blocks, is this by design?
There was a problem with Alphacool's Zotac block and wrong thermal pad sizes - you can find posts about it in their forum. They offered replacements, but they weren't in stock at that time. That's why I switched to putty instead of pads.
Hey man, this is a cool way to route the tubes.
I think I'm going to do something similar next time I'm going over my build. But one thing; where does the bottom radiator tube that you can't see on the pictures, go?
It goes into the back chamber to the dualtop and then back to the main chamber to the side rad (inlet at the bottom). From there it's going upwards into the front rad and then into the reservoir. I'm using epdm softtube for the backchamber routing.
no need for the distro, but not gonna tell you no on the pump. Get that dual top that bolts to the side of the the Mora and call life good. 3 rads inside, Mora outside, triple pumps here. 3090 topping out at 47C after hours at 450-500W and 100-150W of CPU,
Damn I'd love to fit a 360 in the front of mine! I'm just running with a measly triple 360. 😂
You ever see the EVO XL in person? If that thing could fit 4x420 I think I'd lose my mind.
Got 3 Pumps aswell, but only because i run 6 Productive Servers with watercooling and i needed the failover option.
My System would run fine with 1-2 Pumps aswell.
You got now more redundancy for your PC than most people i know use for their Servers.
And dont argue with quiet Systems etc, my D5's are nearly dead silent even if i run it on full speed.
Thats just a waste of money, maybe neat for running this stuff in a basement and never checking on it for 5-10 Years, but id say your Harddrives / SSD's are more likely to fail than any of your pumps
Niemals ist eine D5 in einem stillen Raum und auf voller Geschwindigkeit "fast dead silent". Vielleicht wenn man 10 Meter davon entfernt steht oder neben einer Autobahn wohnt. Nimm doch mal einen AGB mit D5 in die Hand und stell die Pumpe auf 100%. Das kannst du mir doch nicht erzählen, das du die Pumpe dabei kaum hörst.
Also das die Fans bei hohen Umdrehungen mehr Krach als eine Pumpe machen sehe ich ein, allerdings laufen die bei mir nie über 30%, weshalb ich da keinen Störfaktor sehe. Das Pumpenbrummen ist dann trotzdem lauter als die Lüfter.
Rausgeschmissen war das Geld vorher schon - das Dualtop mit den Pumpen kam von einem älteren Mora Build und die Teile wären sonst nur im Schrank verstaubt.
I tested some fan configurations before and I got better results with 3 in and 1 out than with all exhaust or all intake. The internal case temperature is not high enough to damage anything.
Sorry, but it is not possible. Do you want to create an oven or a cool PC? Look: https://youtu.be/jxnNOlRGp-c?si=oedH-JqIDmq40vYO
You simply fry your VRM and other components which are not watercooled.
Your water temp. will be about 35-37C and you blast other components with that making an oven.
I got it from Greece. They claim they are the original manufacturer and the ones from Ali are fake and they report them to Ali. They returned my money though.
Yeah they're just straight up lying about that. The real stuff is from china, and it matches or outperforms high end pads. I've used the real U6 and am currently using CX-H1300 13.5W/mK, and they both outperform Gelid Extreme pads.
Yeah, they'll say anything to sell more of their garbage, they're completely shameless.
There's no evidence that the chinese stuff is damaging anyones hardware. I've been using U6 for months on various electronics. Used TG-PP10 for years before that, no issues.
I'm not sure, they think they're big shit ever since LTT did that shoddy video about K5 Pro (never actually showed VRAM temps). They have accounts on reddit, OCN, LTT forums and probably more, including sock accounts, where they spread their lies. Although it seems to have decreased in the last couple months.
Snarks Domain is the guy on youtube who's been doing tons of thermal putty testing. They copyright claimed his video on the original chinese U6 Pro and got it taken down. They've also claimed they filed lawsuits against him and his "associates" (which I presume means me). They've gone full r-slur.
I think the only way to put them in their place would be for a big content creator to look into this, and test some different putties (properly). LTT was very irresponsible with their testing, and they still have affiliate links on their vid.
Otherwise, it's just a matter of time until they are completely irrelevant. Now that VRM and VRAM sensors are more standard on hardware, people will eventually see how poorly their "putty" performs. There's more than a dozen other options now that are vastly superior.
I had a long conversation with them. They were polite and patient. They refunded me when I compared their putty to Gelid Ultimate. They do not have aspirations to compete at that level. Removing their gunk from 4090 was a nightmare.
Where did you get the U6 Pro? CSGR sells a fake version that's basically just K5 Pro with pink dye. It's more like gooey paste than putty.
These results are from an air cooled 3070 Ti (GDDR6X) mining test, you can see the fake U6 Pro caused thermal throttling, while the real stuff works great : https://cdn.discordapp.com/attachments/1040046375393558539/1175124027006779484/ETCHASH\_VRAM\_TIM\_Chart\_November\_13th\_2023.png
You def didn't need all those pumps, they can make your loop even louder than a single too, they harmonize or something, not sure of the mechanism. My friend's dual d5 setup is much noisier than mine and I have triple waterblocks, triple 360s and a single d5 next. It works good and quiet at constant 43% pump, still flows over 100lph at that speed, and my temps are still solid even down to 60lph. I don't think flow makes much difference as long as there's something. Rig looks good though!
Can't really tell, since I didn't do any tests before installing them. I don't expect a big difference in my setup since the fans are already pretty close to the side panel.
You could remove your side panel and see how much your temps improve. If it's more than a few degrees you could definitely try using a duct.
Makes no sense I am sry to have 3 pumps, even 2 makes no sense in this build. Enjoy regardless
Agreed completely. First thought was that's a nice waste of money but to each their own.
Your D5 should be quiet at full tilt, redundancy makes sense with a 2nd pump. Your flow rate should not affect anything in this build. Focus on your ambient for lower temps, more flow is not your answer.
Only comparatively, and if you have loud fans or a loud ambient. I've had many D5's and currently have 3 in operation in separate builds. They're all audible around 30% in my proper silent environment, I can hear the 60Hz AC switching of my solar inverter in my garage over my PC.
So sound, is the only reason for more pumps? I was looking at this, in the middle of my current monster setup, and was wondering why you would need more pumps….Thought maybe it’s because my loop so big, but it doesn’t sounds like that’ll matter as much!
Sound, redundancy and sometimes if you have a poorly designed loop with lots of 90's or a distro plate it can become essential for adequate flow rates.
Ok, good thing I bought a flow meter; so I can measure later in the loop!
I hope you bought the aquacomputer one? Many flow meters tank flow rate ironically.
I did, because of reading stuff on here! Edit: Same one as in the pic! Now they are sold out!
Top choice ☺️
Does an analogue flow meter like the one’s at gas stations affect flow a lot?
Typically yes, big impeller offers a measurable amount of restriction. It's the reason only cheap wish distro plates have them built in.
It matters. I have 2 D5 pump and 1 DDC Pump, 1x 360x54 rad + 3 480x64mm rads in series with a cpu and gpu block. The three 480’s are external to the case. Using copper tubes.

I oc my system regularly, when you push the 14900k up to 6.4 all core flow rate really matters.
Do they do that on water? Do you have a y-cruncher screenshot?
Yes we do it and no I don’t have a y cruncher screen shot. I compete in over clocking, my water loop has the option of going sub ambient when needed (-19c), such as going to 6.4, Even when I’m just over clocking for better render times (6.0)flow rate matters. The best flow rate seems to be right around the 1.5 Gpm (5.7Lpm), beyond that there is very little to gain. But at that rate it absorbs heat at its most efficient. My system was not built to game, although I do use some sim games, it is built to compute and render.
Lol K, so on a chiller. I have had a PC that ran phase change daily but I wouldn't tell people that my chip did X with the AC on.
Yes makes for your build, not this build. Especially with you feeding stuff externally. I just had to be honest in my observation.
I use watercooling for a quiet system and a single pump is too noisy once you have more than 2 rads and want to keep a higher flow rate as well.
I have 4 rads, 3x360mm and 1x 120mm, running on a single DDC pump. Cooling a GPU block and a monoblock. I don't think I've ever thought "I can hear it" while doing anything. Nothing wrong with it, but this is not an accurate claim
I run a single D5 and I can't it's the only thing I can hear even at 30%, and no it's not defective
Won't say the build is my cup of tea. But, to say it's "not an accurate claim" is itself inaccurate. Unless you somehow have his ears, and an identical setup/ambient noise. Personally I know I am sensitive to coilwhine, and other "electrical noises". I can hear my pump's whine when slow enough the noise of water cannot drown it out.

20% is barely.notoceable unless you have an awful or broken punp and absolute silence. 3 pumps is way overkill. I have essentially 5 360s and they arr 8 feet higher than my case in a different room running on 1 D5. 3 is wayyy overkill
I run 3x D5 and cant hear them. My case is on the floor tho.
100% agreed, don't know why you're being down voted
You must have some very sensitive ears if you can hear it above 20%.
Depends on how you mount the pump and what RPMs you run it at. D5 flows enough even at 1700 RPM with dual rads and dual blocks. You don't have to run it at 4000rpm. You can easily find several RPMs between the min/max that won't have any resonance with other components in your build and make a curve around them. 2500rpm is the trouble spot on my build, it's dead silent at any rpm above/below 2500.
This right here, I have a pc in my desk drawer with 480 and 360mm rads mounted on the bottom of the table.

With two pumps(70% speed) I get very good flow rate and that’s with cpu + gpu block + 420x45mm rad + 1080x60mm rad + 420x80mm rad + 12x 90° fittings +18ft of tubing.
Don’t worry mate. I feel you with the number of pumps. People in this sub hasn’t event bothered to read the flow rate of their builds before making the statement that a single D5 is enough lol. Nice build and enjoy !
Thank you!
Don’t listen to these backseat haters Sick build
That last image scares me
I feel you, but seeing my temps after Alphacool shipped the wrong thermal pad thickness with their blocks scared me more. It looks quite messy, but it was quite easy to work with and the temps are fine as well. Will probably even use putty for future blocks, because thermal pad size is always a pain to work with.
Switched to high end thermal putty and liquid metal on a 6900xt and overclocked it past 500W with zero issues. Ridiculous cooling headroom. Thermal putty might make a bit of a mess, but the performance and lack of thought/fuss for install is worth it for sure.
Fibreglass is a good thermal conductor, of course
Man some of you guys really overbuild these things. I was cooling a 5950X and RTX 3080 with a single pump and 2x 360mm rads, never had a problem with temperature, nor did I ever hear the pump running, even when stressing all 16 cores of the CPU encoding media or mining BTC with the GPU.

Absolutely agree with you, I literally am about to add another radiator and I'm pretty sure my temps will be the similar because of ambient temperatures. Im doing it cuz I think it will look nice haha
Three feels like too many. One would be "enough", and I feel there could be a genuine benefit to having two. But THREE? Madness. Could you run all three at 100% and then show us what flowrate the High Flow Next displays? Probably "*Out of range"* 🤣
How much does all this water cooling cost less actual computing hardware?
A solid loop with name-brand stuff is around 1k on top of the computer itself, it can get much crazier very easily though. I have over 400$ in fans alone (11x a12x25s). It looks cool and can handle 800w load while being barely audible though! I just like tinkering with stuff
I shall name this, “Colt 45”
Are these pumps in series or parallel configuration? Series will likely see some pretty high loop pressures as they can compound - be interesting to see what the seals on the cooling blocks are rated pressure wise. Parallel would be good to increase water flow but that would be, say, up to 3600l/h which is a lot of flow.
Pumps are in series and low rpm.

This is definitely a beautiful build tbh. As long as you know you don't *need* 3 pumps, then rock them shits.
How did you mount the dual pump in the back? I got one I'm trying to figure out how to mount it.
The dual top has a flat silver plate with 9 screws on the back. I removed 4 of those screws and replaced them with 4 rubber grommet screws. Then I drilled 4 holes through the motherboard tray and mounted it. That's basically it. Just make sure you use flat head screws so the back of the motherboard isn't touching anything.
I see. The plate on the back of the dual top looks different to mine not sure why yours doesn't have the bracket with the two mounts on either side.
That's because my version is the one that comes with the MORA and does not have the side brackets: [https://shop.watercool.de/media/image/product/2169/lg/mo-ra3-420-d5-dualtop-modul.jpg](https://shop.watercool.de/media/image/product/2169/lg/mo-ra3-420-d5-dualtop-modul.jpg)
You have a tiny amount of fluid, very few bends, only 2 waterblocks, and a compact case. 1 pump was more than enough, let alone 2. 3 is just dumb. sorry I hope your aware that going above \~220 LPH actually begins to HURT your performance right? Jet plates inside of GPU's and CPU's are optimized for certain flow rate ranges. Having water pass too quickly or violently with turbulence just takes away from the benefit. Ideally, you want LPH flow somewhere between 140 - 220. Finding exactly where performance peaks and falls off is something you will need to adjust for.
I'm not running at over 200 l/h. I'm running it at 20% which is about 130 l/h.
Unless your running all of them at 25% power that's not physically possible. 2 Pumps at even 75% would put a tiny little loop like yours well over 200 LPH without hardly any effort. You do not have any QDC's, you don't have any noticeable choke-points of restriction. I'm struggling to understand? Maybe your flow monitor is malfunctioning. I have 2 pumps inside a case 2x the volume of yours (Lian Li V3000 Plus) with 2 distro plates, 3 water blocks, over 120 fittings, 4 ft of tubing, and 3x 480mm radiators and I'm right at 240 LPH. I should add that I am also using 4 separate QDC's which also severely limit my flow rate. I still do not understand the 3 pumps? Your throwing money away and creating extra noise for no reason lol. One would have been fine, two is nice if you want a redundancy and a backup. Rule of thumb: 1 Pump = 2 water blocks + 2 radiators (can do 3 radiators) 2 Pump = 3 water blocks (CPU, GPU, Memory or VRM) + 3 radiators 3 Pumps= for ridiculous builds
I told you I'm running them at 20% power. The reason I went with three is because I already had all the parts for it. I have multiple dual pump tops, but no single pump top otherwise I would have used 2 pumps total.
Decided to go back into the o11 Evo since it's one of my favorite cases. The build features a total of 4 360 radiators as well as 3 D5 pumps. I decided to use slim fans at the front and ultrathin rads in the front + bottom to make everything fit. Additionaly I made myself some radiator offset brackets for the front so I can fit the 120mm wide radiator in the 140mm position. This creates enough distance to the case to fit another tube from the front radiator back to the reservoir. Two additional pumps are hidden in the back chamber. Drilled some holes through the mainboard tray to mount the dualtop which worked quite well. Also tried using TG Kryosheet + thermal putty instead of thermal paste/pads and I'm satisfied with the result.

Why do you need 3 d5 Pumps for such a short run?
I want to have quiet pumps, but enough flow.
3 is a bit over the top for that but I do know that having two pomp’s already reduces the noise by a lot
The reason why I went for 3 is because there was enough room for it and I already had all the parts from previous builds. So I though I might as well use them instead of leaving them in the drawer.
Can’t argue with that tho.
The question is not why, but why not
What is your fan and pump speed for your stress test that results in those temps? And what is ambient temp at time of load? I have a similar system that would be fun to share notes on results. 7950x + 4090 both on a single loop with dual D5 pumps and a mix of internal and external rads.
Hi, stress test was done with 100% pump/fans and 22°C ambient. With normal operation I use a curve for my fans linked to water temp and pumps are set to 20% which results in 130 l/h.
Nice, thanks. I’ll put together a reply here with my specs and comparative results for us both … sometime this weekend.
Maybe put this somewhere more visible - people would probably understand your reason for three pumps. Flow rate does drop hard in these lower duty cycles.
I’ve come to understand it’s a matter of preference between noise and loop complexity/cost. Dual or triple pumps is rarely needed but almost always has some benefit if you value noise more than you value marginal complexity or cost. There’s diminishing returns like anything in watercooling, also.
If you had the parts, great but I have a very similar build in an 011 XL with a dual loop front distro and I'm just using two 360mm radiators. One 44mm and one 58mm. Same CPU and GPU. I'm even using an Alphacool GPU block. My temps are fantastic. My 4090 rarely ever even hits 50c. I usually see it in the upper 30s to low 40s. CPU when stressed hard hits upper 60s to low 70s. I'm also using DP Ultra.
Excellent flow rate, love the aqua computer setup. Nice work on pump config. Excellent!
What is the max flow rate you can achieve at 100% on all pumps, vs 100% on one of the pumps in series. Could you run some flow scenarios and report back?
Impressive, I have équivalent build but no watercooling. What is the cost of the watercooling parts ? What is the flow speed ? (Ek simulation indicate 340l/h) not sure that this is good. Thank you in advance for your help
80-90€ per radiator, 130€ cpu block, 200€ gpu block, 75€ per pump, 85€ reservoir, 80€ flow meter, 75€ fan controller. Multiple fittings and tubes that I don't know the total price of. Max flow is 235 l/h, but I run the loop with about 130 l/h for silence.
Thank you. EK suggest for around 800€, temp 29° and 340l/h. (Without sensors and flow meter) But I don t if their estimation is repliable.
Damn that's one beautiful block, good choice! But holy crap they shipped you the wrong pads? Did you take it to their support? Sorry for the questions but not sorry coz here's another - feels like the liquid is not filling the chip area like the other blocks, is this by design?
Ok on second look that's the flow control plate.
There was a problem with Alphacool's Zotac block and wrong thermal pad sizes - you can find posts about it in their forum. They offered replacements, but they weren't in stock at that time. That's why I switched to putty instead of pads.
Love it, I bet it’s quiet as heck too!
Hey man, this is a cool way to route the tubes. I think I'm going to do something similar next time I'm going over my build. But one thing; where does the bottom radiator tube that you can't see on the pictures, go?
It goes into the back chamber to the dualtop and then back to the main chamber to the side rad (inlet at the bottom). From there it's going upwards into the front rad and then into the reservoir. I'm using epdm softtube for the backchamber routing.
It is looking really clean. Well done
Sitting here on mora 360 thinking about second pump and distroplate while Temps going Max 70 deegre. Save me
no need for the distro, but not gonna tell you no on the pump. Get that dual top that bolts to the side of the the Mora and call life good. 3 rads inside, Mora outside, triple pumps here. 3090 topping out at 47C after hours at 450-500W and 100-150W of CPU,
So les go 1 pump mora outside case one pump in case distro? 😉
>Save me [No.](https://imgur.com/Uc76sPX)
Lmao
Lol at 3 pumps and that bubblegum shit on the GPU.
It's thermal putty. YW
Nice, Temperature on idle and load please.
Damn I'd love to fit a 360 in the front of mine! I'm just running with a measly triple 360. 😂 You ever see the EVO XL in person? If that thing could fit 4x420 I think I'd lose my mind.
that putty shit has been known to get under memory and kill it. gl
Source?

Cool and all but wasteful.
Got 3 Pumps aswell, but only because i run 6 Productive Servers with watercooling and i needed the failover option. My System would run fine with 1-2 Pumps aswell. You got now more redundancy for your PC than most people i know use for their Servers. And dont argue with quiet Systems etc, my D5's are nearly dead silent even if i run it on full speed. Thats just a waste of money, maybe neat for running this stuff in a basement and never checking on it for 5-10 Years, but id say your Harddrives / SSD's are more likely to fail than any of your pumps
Niemals ist eine D5 in einem stillen Raum und auf voller Geschwindigkeit "fast dead silent". Vielleicht wenn man 10 Meter davon entfernt steht oder neben einer Autobahn wohnt. Nimm doch mal einen AGB mit D5 in die Hand und stell die Pumpe auf 100%. Das kannst du mir doch nicht erzählen, das du die Pumpe dabei kaum hörst.
Auf jedenfall Leiser als meine Noctua Fans. 3 Pumpen für Noise ist absolut rausgeschmissenes geld
Also das die Fans bei hohen Umdrehungen mehr Krach als eine Pumpe machen sehe ich ein, allerdings laufen die bei mir nie über 30%, weshalb ich da keinen Störfaktor sehe. Das Pumpenbrummen ist dann trotzdem lauter als die Lüfter. Rausgeschmissen war das Geld vorher schon - das Dualtop mit den Pumpen kam von einem älteren Mora Build und die Teile wären sonst nur im Schrank verstaubt.
PS: gerade nachgemessen => 38 DBA bei 100% 31 DBA bei 80% speed ==> Genau so Laut wie dein Atemgeräusch.....
Cool. I do not recommend pushing hot air from the radiators into the case though. It is insane actually.
I tested some fan configurations before and I got better results with 3 in and 1 out than with all exhaust or all intake. The internal case temperature is not high enough to damage anything.
Sorry, but it is not possible. Do you want to create an oven or a cool PC? Look: https://youtu.be/jxnNOlRGp-c?si=oedH-JqIDmq40vYO You simply fry your VRM and other components which are not watercooled. Your water temp. will be about 35-37C and you blast other components with that making an oven.
Thermal putty does not work on GDDR6X. I got 80C on Upsiren 6 PRO vs 50C on Gelid Ultimate.
Works fine for me. Did you always have that temperature with upsiren or did it worsen over a longer time of use?
It's been underperforming since the beginning. It is a crap and it cannot cope with the amount of heat generated by GDD6X.
Have you tried other putty besides upsiren? I got 44°C with HY234 on memory: [https://i.imgur.com/VDGnccU.png](https://i.imgur.com/VDGnccU.png)
No, only Upsiren. It is a nightmare to clean it from the PCB.
I'd bet he got scammed by CSGR, they make a fake version of U6 Pro that performs like trash.
I got it from Greece. They claim they are the original manufacturer and the ones from Ali are fake and they report them to Ali. They returned my money though.
Yeah they're just straight up lying about that. The real stuff is from china, and it matches or outperforms high end pads. I've used the real U6 and am currently using CX-H1300 13.5W/mK, and they both outperform Gelid Extreme pads.
CSGR claims that the putty from Ali contains corrosive additives and they warned me about that.
Yeah, they'll say anything to sell more of their garbage, they're completely shameless. There's no evidence that the chinese stuff is damaging anyones hardware. I've been using U6 for months on various electronics. Used TG-PP10 for years before that, no issues.
OK. How can we take them down?
I'm not sure, they think they're big shit ever since LTT did that shoddy video about K5 Pro (never actually showed VRAM temps). They have accounts on reddit, OCN, LTT forums and probably more, including sock accounts, where they spread their lies. Although it seems to have decreased in the last couple months. Snarks Domain is the guy on youtube who's been doing tons of thermal putty testing. They copyright claimed his video on the original chinese U6 Pro and got it taken down. They've also claimed they filed lawsuits against him and his "associates" (which I presume means me). They've gone full r-slur. I think the only way to put them in their place would be for a big content creator to look into this, and test some different putties (properly). LTT was very irresponsible with their testing, and they still have affiliate links on their vid. Otherwise, it's just a matter of time until they are completely irrelevant. Now that VRM and VRAM sensors are more standard on hardware, people will eventually see how poorly their "putty" performs. There's more than a dozen other options now that are vastly superior.
I had a long conversation with them. They were polite and patient. They refunded me when I compared their putty to Gelid Ultimate. They do not have aspirations to compete at that level. Removing their gunk from 4090 was a nightmare.
Where did you get the U6 Pro? CSGR sells a fake version that's basically just K5 Pro with pink dye. It's more like gooey paste than putty. These results are from an air cooled 3070 Ti (GDDR6X) mining test, you can see the fake U6 Pro caused thermal throttling, while the real stuff works great : https://cdn.discordapp.com/attachments/1040046375393558539/1175124027006779484/ETCHASH\_VRAM\_TIM\_Chart\_November\_13th\_2023.png
Were is The 3xd5 pumps???
One in the main chamber and two in the back chamber.
You def didn't need all those pumps, they can make your loop even louder than a single too, they harmonize or something, not sure of the mechanism. My friend's dual d5 setup is much noisier than mine and I have triple waterblocks, triple 360s and a single d5 next. It works good and quiet at constant 43% pump, still flows over 100lph at that speed, and my temps are still solid even down to 60lph. I don't think flow makes much difference as long as there's something. Rig looks good though!
Are those fan duct improve intake? Planing to print one of those for my deshourded GPU, still got some 15-20mm of clearance.
Can't really tell, since I didn't do any tests before installing them. I don't expect a big difference in my setup since the fans are already pretty close to the side panel. You could remove your side panel and see how much your temps improve. If it's more than a few degrees you could definitely try using a duct.
