3x 6970's and 2600K, how many radiators?

post #1 of 8
Thread Starter 
Up in the air build.
Raven RV02
3x 6970s
1x 2600k

I can mount 3x120 rad and a 1x120 rad internally. Both are single height. Will these keep the CPU/GPUs cool under overclocking or will I need more/bigger rads?

Usually you want at least one 120 worth of rad for each thing that needs cooling. So I think you'd be fine with that using some quality rad/fans.

I run a triple RAD for my set

I think a 480 RAD would be ok with a good pump

I think the single slot radiators will be pushing it, depends on how much OCing room you want, and the fans you are using.

With that radiator size you could either have great temperatures or a disaster. What speed of fans will you be using?

I like and use Martin's (@skineelabs) radiator estimator (can be downloaded HERE for some radiator manufacturers). This can then be used, along with info of other components in your loop, to estimate GPu and CPU temps.

Below are estimated temps of your setup, with 1x, 2x and 3x XSPC RS360 rads and decent waterblocks and TIM. Hopefully I got the calculations right



For 1x 360mm XSPC RS360
Assume ambient temp (fan air in temp) is 25C
Thermal Resistance of 1x RS360 rad is 0.0147C/W
Thermal Resistance of good TIM averages around 0.02C/W
Thermal Resistance of good CPU waterblock averages around 0.04C/W
Thermal Resistance of good CPU waterblock averages around 0.05C/W
TDP of 2600k is 95w
TDP of 6970's is 300w

Some calculations:
Tc = Estimated CPU Temperature
Ta = Ambient Temperature
Rfa = Thermal Resistance of Radiator(s)
Rsf = Thermal Resistance of CPU waterblock
Rint = Thermal Resistance of GPU Waterblock(s)
Rtim = Thermal Resistance of TIM
Qcpu = TDP of CPU
Qgpus = TDP of all GPUs
Qgpu = TDP of GPU
Qpump = TDP of Pump(s)

Tc = Estimated CPU Temperature at 100% load
Tg = Estimated GPU Temperature at 100% load
Ta = 25C
Rfa = 0.0147C/W
Rsf = 0.04C/W
Rint = 0.05C/W
Rtim = 0.02C/W
Qcpu = 95W
Qgpus = 900W
Qgpu = 300W
Qpump = 15W

Tc = Ta + (Rfa x (Qcpu + Qgpu + Qpump)) + ((Rsf + Rint + Rtim) x Qcpu)
Tc = 25C + (0.0147C/W x (95W + 900W + 15W)) + ((0.04C/W + 0.05C/W + 0.02C/W) x 95W)
Tc = 25C + (0.0147C/W x 1010W) + (0.11C/W x 95W)
Tc = 25C + (14.847C) + (10.45C)
Tc = 50.297C

Tg = Ta + (Rfa x (Qcpu + Qgpu + Qpump)) + ((Rsf + Rint) x Qgpu)
Tg = 25C + (0.0147C/W x (95W + 900W + 15W)) + ((0.04C/W + 0.05C/W + 0.02C/W) x 300W)
Tg = 25C + (0.0147C/W x 1010W) + (0.11C/W x 900W)
Tg = 25C + (14.847C) + (33C)
Tg = 72.85C



For 2x 360mm XSPC RS360
Assume ambient temp (fan air in temp) is 25C
Thermal Resistance of 2x RS360 rad is 0.0073C/W
Thermal Resistance of good TIM averages around 0.02C/W
Thermal Resistance of good CPU waterblock averages around 0.04C/W
Thermal Resistance of good CPU waterblock averages around 0.05C/W

Rint = 0.05C/W
Rtim = 0.02C/W
Qcpu = 95W
Qgpus = 900W
Qgpu = 300W
Qpump = 15W

Tc = Ta + (Rfa x (Qcpu + Qgpu + Qpump)) + ((Rsf + Rint + Rtim) x Qcpu)
Tc = 25C + (0.0073C/W x (95W + 900W + 15W)) + ((0.04C/W + 0.05C/W + 0.02C/W) x 95W)
Tc = 25C + (0.0073C/W x 1010W) + (0.11C/W x 95W)
Tc = 25C + (7.373C) + (10.45C)
Tc = 42.82C

Tg = Ta + (Rfa x (Qcpu + Qgpus + Qpump)) + ((Rsf + Rint) x Qgpus)
Tg = 25C + (0.0073C/W x (95W + 900W + 15W)) + ((0.04C/W + 0.05C/W + 0.02C/W) x 300W)
Tg = 25C + (0.0073C/W x 1010W) + (0.11C/W x 300W)
Tg = 25C + (7.373C) + (33C)
Tg = 65.37C



For 3x 360mm XSPC RS360
Assume ambient temp (fan air in temp) is 25C
Thermal Resistance of 3x RS360 rad is 0.0049C/W
Thermal Resistance of good TIM averages around 0.02C/W
Thermal Resistance of good CPU waterblock averages around 0.04C/W
Thermal Resistance of good CPU waterblock averages around 0.05C/W

Rint = Thermal Resistance of GPU Waterblock(s)
Rtim = Thermal Resistance of TIM
Qcpu = TDP of CPU

Qgpu = TDP of GPU
Qpump = TDP of Pump(s)

Tc = Ta + (Rfa x (Qcpu + Qgpu + Qpump)) + ((Rsf + Rint + Rtim) x Qcpu)
Tc = 25C + (0.0049C/W x (95W + 900W + 15W)) + ((0.04C/W + 0.05C/W + 0.02C/W) x 95W)
Tc = 25C + (0.0049C/W x 1010W) + (0.11C/W x 95W)
Tc = 25C + (4.949C) + (10.45C)
Tc = 40.40C

Tg = Ta + (Rfa x (Qcpu + Qgpus + Qpump)) + ((Rsf + Rint) x Qgpus)
Tg = 25C + (0.0049C/W x (95W + 900W + 15W)) + ((0.04C/W + 0.05C/W + 0.02C/W) x 300W)
Tg = 25C + (0.0049C/W x 1010W) + (0.11C/W x 300W)
Tg = 25C + (4.949C) + (33C)
Tg = 62.95C







EDIT: The above are at stock CPU and GPU speeds using stock TDP values. If you overclock the CPU or GPUs, the TDP will be high and you'll have to redo the calculations.

By single height you mean that you don't have room for the thicker radiators and need to use the thinner ones? I think you will be okay with a 360 radiator combined with a 120 radiator with 3x6970's and a 2600k CPU. if you have clearance, the thicker radiators will give additional cooling power. Either way, you will be much cooler than trying to overclock everything on air.
