I overclocked my q6600 from 2.4 to 3.0 ghz without changing any voltages. The strange thing about this is, sometimes the temps will be around 57-63 on core temp and other times it will be as high as 77 - 84.
The temps randomly jumped up and down. Is this normal? I am looking at it right now and it doesn't go over 30% load. Seems like the average load right now is areound 17-20 ish.
Temps will randomly jump with processor load no matter what you are clocked at. Chances are you never paid much attention to your templs until after you overclocked and noticed these "spikes". This is a normal phenomenon.
Even though you should probably invest in some kind of after market cooling if your running on the stock cooler.
