Now, before you all recommend the obvious choices for a new hsf, hear me out. I have an Arctic Cooler 64 Pro that previously was keeping my overclocked 90nm X2 5600+ cool - to typically around 30c idle / 50 load. Which is now being replaced with a Phenom II 940, that I'm awaiting in the mail. So, I was wondering, since the 940 BE is 45nm -- half the size of the 90nm die of my previous cpu, couldn't it cool the 940 BE just as efficient, given that it's only 45nm? I figured since it'd cool that whoppin', heat-hungry 90nm that good, then certainly it's gonna cool a 45nm better? Granted, 4 cores, but still.
