Planning to build an E6500/P45 system for my folks. I think running it @ 11x333 instead of the stock 11x266 should be easily accomplished. I've read that the stock HSF is both inefficient and noisy. Can you guys recommend a HSF that is: 1) Quiet (120 mm fan probably) 2) Mounts using a backplate to minimize flexing of the MB 3) Relatively inexpensive My only experience with cooling C2D/C2Q chips has been using a TRUE-120+expensive 120 mm fan which is too expensive for this application and probably overkill. Thanks!
