Read a lot about water cooling but am not sure how many radiators I need.

What it is about:

New build for content creation is in the works:
Most relevant load will be GPU und CPU rendering (runs under heavy load for 24 hours). During that the PC is used for other things at the same time (e.g. working on new textures, running new cloth simulations while IRAY, Lightwave or Blender are rendering in the background).

Watercooling planned for two RTX 2080 ti and one Threadripper 3960X

Planned or already bought components:

  • Threadripper 3960X - ordered
  • 64 GB GSkill Trident Z ram (option to go 128 GB) - in the parts box already
  • sTRX4 board with 4 x PCI x16 and 10GB ethernet - ordered (asrock creator)
  • 2 x RTX 2080 ti founder edition (option to go 3 x) for GPU calculations - one is in the box, one to be ordered
  • 1 x RTX Quadro 4000 for display - in the box
  • 3 x Samsung M2 SSDs - in the box
  • 2 Samsung SATA SSDs - one in the box, one later when required
  • water cooling for 2080 ti GPUs - in the box (two EK Vector something)
  • water cooling for CPU - ordered (XSPC RayStorm Neo for AMD sTR4)
  • pump EK-XRES 140 Revo D5 Reservoir pump combo - in the box
  • 3 x EK-Varder 120 EVO static pressure - in the box
  • 1 x EK-Coolstream XE 360 60mm - in the box
  • Case Phanteks Enthoo 719 - ordered
  • PSU Corsair ax1600i - ordered
Is the one radiator sufficient for those components? And is the one pump combo enough even if I would need more radiators?


Thanks in advance for your help.

It really depends on your noise tolerance I run a 280 push/pull + 420 push for a 7980XE + 2 1080Ti. But my system isn't at full load most of the time. If it was, I'd probably add 1-2 more rads.

- Min 2x 420 rad's.

- Average 360 ​​rad per component(3x 360) for a good delta T and fans at 800-1300 RPM range.

- Or a combination of different sizes, depending on the space you have(420+280+240 for example).

Read a lot about water cooling but am not sure how many radiators I need.

What it is about:

New build for content creation is in the works...
Currently I'm running a Treadripper 1590X + one 2080Ti.
I have 3x 360 radiators and 9 fans. The CPU goes to 75C - 85C under load with an OC to 4GHz all core. The GPU goes up to 45C - 50C
Now imagine how much more heat will a 24 core chip plus two 2080Ti cards will be spewing...
The new system I'll be building soon will have those same 3960X CPU and two 2080Ti GPUs, I'll be making two separate loops, one for the CPU and another for the GPUs. The CPU loop is going to be 2x 480 rads and the GPU loop is going to be 2x 480 + 1x 360 rads. All radiators are 60mm thick.
A single 360 radiator with 3 fans (in push configuration) running at about 1300rpm can dissapate about 270w to 330w of heat.
Treadripper 3960x is rated at 280W and most stock 2080Ti's are also arround 280W so arround 840w - 850w for those 3 components only and at stock. (those are overly rounded numbers and may differ depending on the current scenario. And also I know that not all of the electrical power that is consumed by those parts is transferred into heat, but still it's close) To be on the safe side, you will need at least 3x 360mm radiators (and good ones at that) to handle those three componenets loaded at the same time.

OP: Sounds like you're planning a great build !

The more rad space, the better, given the parameters of your build project, and the fact that with more rad space, each fan can be set to a quieter mode. The thickness of the rads also plays a role

Per sig-rig link, I'm running a TR2 2950X with an all-core oc of 4.3 GHz and 2x factory water cooled Aorus 2080 Ti, each of which has an observed max power draw of 380W (so 760W total heat energy just for the GPUs :eek:). I am using separate loops for CPU and GPU.

The CPU loop has dual pumps and dual XSPC RX360x60 v3 rads, along with a Heatkiller IV TR CPU block. The GPU loop also has dual pumps, but uses triple XSPC RX360x60 v3 rads. As you're planning to run the system under what sounds like fairly heavy load 24hrs, it is also not just a question of controlling peak temps, but also heat soak > plenty of rads with big surface area and volume

The short answer is "all of them". As many as your case and wallet can support.

My advice:

-480mm on front -Intake
-480mm on the side - Intake
-420 on top - Exhaust (140mm fans)
-As many bottom fans as you can fit as intake
-Rear 140mm fan as intake? (get a dust filter). Maybe exhaust, I would play with that one to see if there is a difference. I'll ultimately depend on the case static pressure.

For maximum radiator efficiency, run the heat load to your exhaust radiators prior to your front intake radiators.

Hardware Labs Nemesis GTR and Hardware Labs Nemesis GTS recommended. GTS is more for air flow and GTR is more for performance. Maybe two GTR's for intake and a GTS on the top as exhaust to keep case pressure ideal.

Many thanks. Seems so my initial plan of two 360 rads (1 x 60 mm, 1 x 36 mm) might be not so good. Will start with them once the components and case arrived and then see how much space is left. According the case's specs it should swallow plenty of rads but need to see it hands on first to get a feeling.
Damn, feeing so noob at the moment :)

2x360 will work but the fans will need to be at higher RPM (guessing 1500-2000)

You don't need a 60mm rad. Its only useful if you can't fit anymore rads in the case and but you need more surface area.

If you can fit 3 slimmer rads, that would be more ideal. Looking at that rad - 2 x 360 slim + 1 480 slim rads can fit. Or 2 x 480 + 360 slim rad (but it looks more challenging).

But you're right - wait till the case is there and you're able to visualize the space you need + what rads can fit by measuring.

No way will one 360 be enough. That system is going to put out some heat. I would want a 360 per component or you could go external with the mora radiator.

It's an oldie, but here is a straight comparison of XSPC RX360 (approx 55mm thick) and its thinner 360 brother, the XSPC ES360 (approx 35mm thick):

http://www.xtremesystems.org/forums/showthread.php?279985-XSPC-RS360-vs-RX360-360-Radiator-Shootout-Part-1

...obviously, the RX360 holds substantially more cooling medium, contributing to improved results. But at the end of the day, it comes down to available space, fan type and arrangement etc. Given the planned load, it is worth reiterating that a dual D5 type pump arrangement (in sequence) is used 'for insurance'.

...would be nice if the OP can do a build log :)

Everyone always rags on them, but I love my external rads

My two phobyas have served me very well over the years. 18x120 of external rad space is lovely, lol. (The additional 7x120 internally is nice too, haha)

Rediator requirements

You need two morah 420 if You go fanless, and add fans if you are going to add two more GPUS in time..
You will need at least 2 DDC pumps, if you run the radiator next to the desk, and 3 if you decouple it as You should outside eg on Your balcony.
The advantage of placing ur rads outdoors is that You wil get basically only get the pSU heat indoors, and in winter, as long as You are nto below 0 temperatures be able to run yoru gpus at 30 35 c and the CPU at full load around 55c...this wil give you a perfomance boost of minium 5% more likely 10% compared to a in case radiator set up..
The same is true also in the summer season, but if temps get crazy hot you can then move yoru rads indoors in air conditioning....just keep in mind that summer days where temps are realy bad is july and some of august, unless u live near the tropics.

Keep also in mind that if u run Your GPUs in parallel which would be Ideal for this kind of worlkoads you gonna need two ddc pumps feeding right before the gpus inlets, and another DDC pump soemwhere else , preferably form the rads to the CASE...you can opt for an Iwaki pump if u need more power in the flow and head pressure and ur loop exceeds 7 8 meters.(iwaki will use 50 watts easilly, so do ur math properly before u choose what do use).

With this kind of set up you are going to get almost zero component degradation in time, and be able to safely run this system for 15 years or more without any failure of perfomance loss.

I wish to end by saying that I have the same job and it is unthinkable to keep a workstation with its cooling solution in the same working enviroment or anywhere ur desk, for the dust and noise and heat it generates... You want your system to be 100% inaudible when at full load.

You also will want to buy a motherboarrd with overkill VRM so to keep those temps indoors low as possible fans feeding the case that will stay below 20 decibel noise out as few as u can and seal any holes or gapsarpudn teh case , so you wil force the dust regardless if positive or negative prssure into the dust filter only....it appears that from a linus video actually having negative presure pulling air ONLY from the botomn psu filter was the least dusty solution and might be ideal set up as u dont realy need to cool much inside teh case but rather recycle the air in it.

The true problem is cooling a 64 core..whiole it ca run properly with water cooling, it should ideally have a 2 kilowatt chiller running under loads to be used in summer time, and in winter as expained, use outdoors temperautres to keep the cpu cool.

You need tomake sur eyou have a decent airconditioner in you rworking space that is capable of running demositoruszing too..so to keep the ambient dry, so you wil lnever have dew point condensation issues...I never had any condensation issues even when outdors temperatures wehre close to zero and indoors at 20....but if u run masive radiator set up this is a possibility, so it helps to keeep teh rubber tubes goiugn form ur pct to teh rads likned together firmly with some zip ties, so that the heat wil keep the tubes dry.....(You dont want the cool tube to run far from the hot tube).
2 morah 420 will cool 5000 watts with fans and a third without fans keeping teh watwr temperature AlwAYS at the same as ambient which is what you want with systems ruynning 2 3 4 weeks in a row at full load non stop it is not uncommon for me to run my system for a whole working week at full load non stop, and im running two TITAN V and crappy 980ti.
Another alternative is the Airp;lex gigant , get the massive copper version, its easier to move aorund and you can install as many pumps you want in all that space.....and keep them coverd from rain ....if u do wanna rn fans run them in pull...its much faster to vacumm clean the rads lik ethat and u can beep teh fans as thilthy a su want as anyhow they wont degrade in any manner airflow even with mssive amount of crap and crusts deposited on them....rads wil always stay super clean as teh dust wil deposit only on the surface and it wil be super easy to use vacuum cleanr with a brush to clean then im less than 120 seconds eg once every two or 3 months.

Bottom Line...radiators inside a case for 3D animaiton a rendering at work is for noobs and incompetent....especially when you use for this kind of workloads at least 1 hefty CPu, two hefty gpus and ONE more gpu to run ur monitors and viewports, while multitaksing as u rendering.

Speaking of incompetent noobs... You did a good job reviving this dead post :p
