Icrontic's EPIC Socket 775/AM2 Heatsink Roundup Part 2
 

Put simply, the Noctua NH-U12P is a fantastic heatsink. It is a phenomenal performer on both LGA775 and AM2 platforms, is not overly large or heavy and has the best mounting system I have seen to date. The lower fin density of the NH-U12P means that it performs remarkably well with near-silent fans.
