I was cooling this i3 on a stock cooler @ 4Ghz 1.21v and it was hitting 65C linpack. CM 212+ will be fine. Yeah it's not a problem hit me up via pm's. Just remember it's not the heat that kills these chips, it's the voltage. Oh and if you can OC an AMD chip you can OC the i3.
With the dark knight at 4.4Ghz 1.32v I hit 54C linpack, current settings stays at around 50C. Personal usage I'd say about 45C load.
