hey, i'm looking to get a 2500+ and run it on the asus ASUS A7N8X board, but i was curious. i've never OC'd before, but i've read that the 2500+ will easily OC to 2.2 GHz. I probably won't push it that hard for my 1st OC, but i wondered if i want to OC to say 2.0 GHz, and eventually 2.2 GHz, is the stock hsf good enough, or do i need an aftermarket one? any reccomendations and/or places to find reviews? thanks
