I finished my system a few months ago, it was a pre-built Acer and I added a 7970 and a new PSU, but when I took out my old PSU i realized that the only fan in my case (non GPU or CPU fan and heatsink) was wired directly to it. I get highs of 85o C and im worried its going to kill my card. i average about 70-75 but games like BF3 and Far Cry 3 make it really hot. Any fan suggestions? I dont have measurements of my case but the fan has to be on the smaller side. Thanks
