Things could get a bit hot if you go beyond 3.6GHz on a CM hyper 212 Evo, unless the room temps are real cold.
Huh? I'm quite easily at 4.5 on my 2500K with my
Evo. 64C on the warmest core and 58-62 on the others in Prime 95 (73F ambient). In other words, beyond 3.6 on a 2500K with a 212 Evo is child's play.
4.5 is almost a guarantee, and beyond is attainable.
