This may not be relevant to all users here, but after having cooling issues with my i5 system due to a custom mod (passively cooling a 5750 in a half-height case), I found a solution involving switching to positive pressure.
In a vertical orientation, my NSK-1480 has two 80mm fans at the base (one for the 350w PSU), and two 80mm fans at the top. Conventional wisdom suggests intake on the bottom, exhaust at the top.
For awhile, this appeared to work, but I began developing BSODs very frequently a few months ago. I made sure nothing had changed, but something was still wrong.
By changing all four 80mm openings to intake, the majority of the air gets pushed along the video card (whose modded Accelero S1 occupies three slots having been bent into a C shape) and out the expansion slot openings.
My BSODs have disappeared, and I've returned to overclocking the 5750. I can't do much more than 800/1200 with the fans all at the lowest voltage, but at mid-voltage, 860/1260 works fine. At peak (I've only tried with SC2 at 1080p high), the CPU hits around 50C and the GPU hits around 75C, with very little noise produced.
