Case with supposed better airflow and my temps are worse?

post #1 of 5
Thread Starter 
I am not 100% sure this is where this belongs but I've been having this problem for awhile but it has been mostly noticeable since I bought a 2nd 980 Ti. My temps are always high when playing demanding games, even when running everything on 100% fans.

CPU ~ 65-70C
GPU1 ~80-85C
GPU2 ~80-85C

I had a Corsair 750D with my Predator 360 mounted in the roof and the CPU was running cooler @ ~50-60C while gaming but then I swapped to the Fractal Designs Define S I have now and mounted the predator in the front and now I am getting higher CPU temps but the GPU didn't change. I thought originally it was because the 750D had poor airflow and I had heard good things about the airflow in the Define S but now I am worse off but I am not 100% sure why. Does the Define S really have that bad airflow or is it something else? I am planning on buying some watercooling parts in a few weeks to add my 2x 980 Ti in the loop and a 280mm radiator in the roof, but I would prefer to make sure its not the case before I spend that money. I guess what I am really asking is if the Define S has bad airflow or not or if I should just buy a different case with better airflow.

It's not the case it's your front rad blowing warn air on your already toasty air cooled GPUs. The Define S is known as one of the best cases for water cooling. Move the rad back to the top as exhaust for now and when you add the GPUS and new rad make both rads intake and you should be good imo.

Well I figured out the issue, apparently I forgot to reswap my fans on the radiator to intake so I only outgoing air. Makes sense as to why my CPU saw a spike. When running both rads as intake as you described, would you still have exhaust fan as a outgoing or just leave it off the case?

I would still use a rear exhaust fan.

Thanks for the input! Out of curiosity, what part of Texas are you from? I'm in Dallas myself
