First Custom Loop - x99+SLI Rad thickness

[Lathlaer]

Hello,

 

I have a question to those of you who are running a multicore CPU's with SLI and have it all on water.

 

I decided to LC my setup which is i7 6950X and Asus Strix OC 1080ti in SLI. I think I will buy most of my stuff from EK to ensure less headaches with compatibility.

 

I have a question about rad thickness though - I will be running 2x 360mm rads and I was wondering if EK Coolstream PE will be enough for overclocked system (CPU to 4.2-4.4 if I can, GPU as much as I can) - so basically, will 2xPE (40 mm) be enough or do I have to go for the 60mm?

 

FPI of 40mm: 19 (split fin)

FPI of 60mm: 16

 

I don't want too thick rad because I want some air to go to the chasis as well but if 2x360 40mm will not be enough, then I will go for 60

 

Thanks in advance!

for gpus even a 240 would be enough , the problem you have with cpu overclcoking is the bad thermal conductivity of your TIM/solder between your die and HS, maybe you can do 200mhz oc, but dont expect much.

What do you mean the problem I have with the CPU? I was under the impression that doing 4.0-4.2 isn't that hard for i7 6950x, definitely can be done more than 200 mhz oc
