I am a total noob on building and OCing. Here is my spec and I ran Prime95 for 1 hour with no problem so far but the problem is the temperature is really high with core temp (highest is getting to mid 70s) tried lowering the CPU voltage but fail really fast. Any suggestion? Thanks for all your help in advance!
