I take it youre not overclocking?
a lot of people automatically suggest things like a SLK900, which is a superb heatsink but very probably far more expensive and troublesome than necessary if your not cranking the speeds up.
I can reccomend my Taisol GCK670 hsf, got good temps on my 1600+ and 2400+, and is cheap, easy to install and fairly quiet.
I probably pimp
this hsf roundup every time i post in the cooling forum, its kind of huge though so maybe best idea is to scan the column on the right for "0.65" and below [a bit higher should be fine, but no need when there's coolers cheap + quiet that are 0.65c/w or below] or just use to refer to when you pick a few options
