Seriously, the Alpha PAL8942 is hands down the best air cooling heatsink i've ever used. In combination with AS3 and a YS tech 80mm variable, i've been able to drop cpu temps from (idle/load) 42C/59C to an incredible 32C/45C overclocked to 2.88ghz! It's a bit on the pricey side, but i don't regret one penny. Thanks to ChampionatTufshop, OulOat and RalfHutter for helping me choose a combo
Edit: I just checked temps again with prime95. It seems that the AS3 has 'set' and now my temps are 28C/41C now. Amazing! (I might mention, also, that it is especially cold this morning.)
