I overclocked my AMD phenom II x6 1055t from 2.8 to 3.8. Then I ran prime95 for 5 hours without error reaching a max temp of 60 celcius. I have come accross alot of conflicting info on if this is acceptable or not. Some threads have said anything over 55 celcius is too much. And others have said since prime95 pushes the cpu to temps that gaming will never reach that 60 celcius is fine. Also even though it did hit 60 it usually was hovering between 56 and 58 celcius. So who is right?
My celeron reaches temperatures of 75 celcius in just 5 minutes of Prime95 and I haven't had any problems with it...yet. It's slightly overclocked (from 2.6 to 3.0) with stock cooler so I guess you're ok
