I am trying to re-setup my fan configuration to help keep my graphics card cooler. I have EVGA GeForce GTX 970 4GB SC GAMING ACX 2.0. It's loud and while most games on high settings don't heat it up. Newer games are starting to put it at load even on lower settings. It doesn't really get higher than 72C but that puts the fan at 60% and anything higher than 50% is to loud.

I read that most people average 80C at load with there cards so I figure I have it pretty good right now. My PC case is a COOLMASTER it has 1) 120mm in front. 2) 80mm on the side of the case blowing into the motherboard. 2) 80mm fans on top but one is blocked by power cables. 1) 80mm fan on the back.

I have 4)80mm and 1)120mm currently.
120mm in the front is pulling air in
2)80mm on the side the bottom one pulling in air and the top pushing out air.
1)80mm on top pulling out air
1)80mm fan on the back pushing out air.

My original thinking was having all the lower fans pull in air and the top fans push out air. Though I am not sure if my graphics card pulls or pushes the air and I was thinking I should make the lower side fan go with either pulling in more air or pushing out the hot air depending. Any thoughts or suggestions on reorienting my setup. Or is there an AC for computers to cool the air it pulls in ;P.

Air flow is a bit of a headache to be sure. see if you can confirm that it is pulling in air (maybe gointo video card settings and jack up the speed. place a pice of paper the size of the vent if it sticks WINGO you have a pull..

as for air in the case..... it always bugged me that the gpu put hot air in then the the cpu gets all hot and gerrr dumb cases.... sooo.... if the video card is a suxer ;) and the cpu is a blower then we have a lot of hot air in the case. a fan blowing out at the top and a fan suxing in from the botem would be good. maybe a fan blowing in from the bottom front of the case. ? and if looks are not a big hang up for you. cut away a perigees can the bottom and stick it on the cpu fan as a bezel (hopeing you...

looks like you have a blower with means the hot air is vented outside the case. I am pretty sure (could be wrong but the look of it seems to be a blower) Hold a pice of paper up to the back end dose it move ? get pushed away , then blowing out, gets suxed to it then it is suxing.

as for fan set up hot air rises so a blowing out the top and taken in from the bottom is the way to go. make sure fans are clear of cables as well.

I just checked and I am pretty sure air is being pulled in from the back. Right now at idle it wasn't doing enough to move paper but I did the super scientific lick my finger then hold it by the vent and the side facing away got cooler not the front so yea pretty sure its pulling in air which means I need to put that fan on the lower side of the case to also pull the hot air away right? Because I currently have the card in the lower slot to give more room between it and the CPU heat sink and it is also facing fans down.So the GPU is just pushing hot air into the lower case so the lower side case fan is also pushing that air back into the GPU.
Though I also think my CPU heat sink pulls air away from it so would it be better to have both fans on the side facing the motherboard also pulling away the hot air generated by the GPU and CPU?

we used to have bezels in a TON of cases but then enyone was like eww they are not pretty ( -_- )
