Basically I bought an XClio Windtunnel case around 2 years ago on a whim. I didn't do much research into it and just figured it's a full tower case so airflow will be fine with those huge fans.
I bought a 7950 recently and have been really disappointed with its temperatures. It idle's at around 40c on a cold day, add another 5c for a normal day and it pushes 70-80c when gaming, goes to 90c when overclocked
My i5 is another story, with a Cooler Master V8 heatsink, it's average temp is around 28c (min has been 23c today), and that's with it overclocked to 4.4 GHz, so it's not like warm air is hanging about the case?
Yesterday I took the side case off to rearrange cables a little, and just by chance glanced over at my monitor and saw that GPU-Z was reporting it's temp as 36c, how is it even possible for room temperature air to be cooler than it being pumped in by the fans? I have an exhaust fan on the rear, but no front intake. Would that be the problem? I've never bothered because the gaps for the air to come out of the front are so limited (due to the hard drive tray) I've never seen the point.
Am I better off buying a new case with better airflow or just installing a front fan? I've been eying up the Fractal Design R3 and R4's...
