Okay, I recently upgraded from a stock cooler which was giving me completely HORRID temps (up to 95c) while rendering some things with my trusty i7 4790k (running at stock speeds). I upgraded to a Cooler Master Hyper 212 EVO which was recommended to me by an immense number of people, and it seems to be a pretty solid cooler according to the internet, lol. Well, I booted up after installing (no problems, because I'm a pro B) ) and I ran prime95 to torture my cpu with my newly installed cooler and in about 10 mins I hit 77c, but it stayed there, went down, and then came back up. It did not go above that. Are those okay temps for a Cooler Master Hyper 212 EVO with Arctic Silver 5 thermal paste?
