AiO loop for my CPU and GPU

H6NS · August 25, 2020

Hello,

since my original cooling solution on my Gainward RTX 2080 GS is currently broken I'm beginning to think about buying an AiO from brand Alphacool. Specifically Alphacool Eiswolf 240 GPX. And I don't end there. I thought since Alphacool is making these "quick release" tubes so you can easily expand your loop, I would like to buy also Alphacool Eisbaer LT120 for my CPU Intel Core i7 8086K. I know that 120mm rad is not enough, but if I connect it to the loop for the GPU, which has 240 rad, it should behave like a single 360 radiator.

Or am I totally wrong?

It's not quite that simple, but it's close... It's going to be slightly worse cooling than a 360 if you're putting the 240 in the front of your case, and 120 in the rear or top. It'll be significantly worse if you do the 240 in the rear/top and 120 in the front/rear. You also have to make sure you position it all so that all that air bubbles go into one of the radiators instead of one of the pumps. (which is much harder with the two interconnected, and dual pumps) You'll also have increased evaporation of the fluid due to more tubing, meaning the air that will form in the loop will be increased, which could theoretically hurt performance sooner than if they were seperate loops.
