Advise: I bought this CPU Cooler

[kaigen]

man use orthos or prime 95 for check if you did an OK overclock. I have a E8500 at 3.9Ghz with a sun beam tech cooler. You shouldn't arrive to 80ºC. I don't pass 56 on zero core and 51 on the first. Then you shouldn't try to use it with a multiplayer higher than x9,5. If you don't do any stress test FFT you won't know never if it's stable.

First learn then read again and be sure what are you doing...
