Improve GPU temps(blower fan)

post #1 of 6
Thread Starter 
Hello,

I recently got 2x760's in SLI and I am trying to improve my gpu temps a bit. They reach 80-82c max and although that's within the limits I want to try to improve it so that they don't throttle/downclock.

They are blower fan style so the heat goes off from the back. I am using a Corsair 650D case with:

1) Front intake fan
2) Top exhaust
3) Rear exhaust - 2 fans radiator (H80)

What I tried already:

1) Remove the pci things that are not in use
2) Remove one of the Hard drive cages(top one)

Anything else I can try to improve temps? Would one fan blowing air on the gpus help at all?
Like so:

Front fan -> Hard drive cage - > 14mm fan -> GPUS

You need positive air pressure in the case.

I would intake from all fans and exhaust through the two gpu fans

Wouldn't that cause hot air from motherboard/cpu go through the cards? Also dust would be a problem too.

Filters can be purchased if you don't want to clean your case as regularly.

Hot air is less dense than cold air, change your configuration wont help in this case, is just right what you have.
but adding CAI is a must so I would add intakes at the bottom with a plate-filter.

I had seen users with sealed water coolers on GPUs, that's a viable way if price matter.
Also, what's your ambien temperatures? do you play open or close side-panel? those things helps when ambient temperatures are high.

Ambients are about 26c and I am playing with closed panels. I'll try a bottom fan I suppose.
