Hello, I'm sorry if someone has posted this before, but I cannot find any reference to optimal operating temps for the new AM2 processors. I think on AMD's website says the max. temp is upto 70 something but I was wondering if my temps are too high? Now I am using some Antec silver-based thermal paste and I'm not sure if I applied too much or not. It was thicker in some places than others, not uniformly smooth and it covers a lot of the whole die, but not the edges. So should I reapply it? I also initially used an oil-based nail polish remover to clean the cpu and heat sink but have since removed all that and re-cleaned with isopropyl alcohol and reapplied the paste. The heatsink (Thermalright Ultra-120) came with some white paste which I believe would be silicone based, not metallic, which I did not use. Should I use that instead? I'm averaging between 38-48 or so from idle to load. By load I mean I"m recording 2 channels at once from my tv tuner while watching one of them on vista media center. When I stop media center, the temps still stay around 38 and I think they should be lower. I've only done this 2 days ago and maybe I should wait longer for the temps to get lower? BTW, the heatsink is barely warm to the touch, shouldn't it be quite hot? A friend of mine says his are 26 or so at idle and that sounds too low! Mind you, he has extra fans on his case and I'm trying to keep mine quiet. Maybe I need better airflow for my case? I've currently got a 120mm fan on the heatsink and 1 more 120mm fan in front of the case, blowing air outwards. I've read in many places that this is wrong and it should be *sucking* in air from outside, not pushing it out? I'm also supposed to add 1 more fan to the back of the case?
