So recently i INSTALLED the cooler master hyper 212 plus into my gaming pc because i planned on OCing. I FOLLOWED an overclocking guide from http://forums.overclockers.co.uk/showthread.php?t=18338090 and it worked pretty MUCH at 4.5. The only problem is the heat. Running prime95 for a minute got it close to 85c then i turned it off because i thought that was too high. So i started to crank it down and now its at 4.3ghz and about 1 1/2 mins in it goes to 83c and i shut it off. Thats how it currently is atm, idle it stays around 45c. I think this is too hot, is this normal? Thanks Also i forgot to mention, on every game i have tried with low and high settings, i always get around 60c which is high but fine i guess, i just dont want my pc to be too hot this summer.Just undid the overclock and tested prime95 again and now it stays between 72 and 73 c. I think there must be something WRONG or something i did wrong.Sounds as though your cooler isn't doing its job properly if your temperatures are reaching 73C at stock.  I would reseat the cooler to make sure it's making good contact with the CPU and then re-test at stock to check your temperatures are acceptable.  Might also be worth checking what CPU voltage is being applied at stock with CPU-Z, you MAY just have an unusually high stock voltage.
