hi. Currently i have my heatsink positioned so that the fan blows upward (my reasoning is that since hot air rises, it might push the hot air out faster). However i get the feeling most people have it blowing towards the rear. Which position is optimal for good air flow?
I have my cooler oriented vertically to take advantage on the large fan at the top of my Antec 900 cases. I plan on tearing down one of my systems and experimenting one of these days, but there is no hurry.
I have three highly overclocked Intel Core2 systems and they have all reached CPU core speed limits without exceeding Intel's recommended voltage or thermal limits.
