I have a pc with an intel motherboard, D945GTP, and a p4 3.0 GHz, 2 gig or kingston ddr2 800. using onboard video. Running stable. I wanted to overclock. and did. got it to 3.4 and was using memtest to stress it. it was giving me no errors. but I can see the preformance is off. pages load slower and there is some jerky something going on when I try to move things fast to check for just that.I did notice that it was kind of hot.this is at around 45c at idle and gets up to 55c on memtest. this is the fan that came with the processor. I cleaned and reapplied artic 5 paste, not to much. I guess I also wonder how hot is too hot ?
