A friend mentioned reversing the airflow on his heatsink, I've heard the idea tons of times but I never considered trying it for whatever reason. Anyhoo, I turned the fan over tonight so it pulls air up through the heatsink and out the top instead of the other way around. The 140mm PSU fan and 120mm case fans pulls the hot air right out as soon as it leaves the heatsink. The improvement in airflow dropped my case temps 5C and my CPU temp 4C, I was a bit startled at first.

Depending on your case setup,fans, cpu, etc, I would strongly urge you guys to give this a shot, its extremely easy and you don't have much to loose! I would imagine this is a best case senario and others could easily have the opposite effect. Eitherway, try it!

heres a picture of my case setup before the change, there is a second 120mm fan mounted to the drive case for intake and cross flow thats out of the picture also.

I tried it, and always try it out in different case/fan configurations. On a P4/SP94 setup a while back, I got a 3C-4C change in the wrong direction on "pull", but in other systems I've gotten better results on "pull" rather than "push".
