Radiator requirement for new Threadripper content creation PC ?

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).

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 ). 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.

Asus Prime Z370, Intel 8700k @5.0Ghz, Nvidia GTX 1080 Ti, 16GB @3400 CL14, Watercooling: x2 MCP355 pumps, x1 280 on front of case, x1 360 on top of case, x1 140 on back of case, x1 240 on bottom of case

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.
