Well I'm using PC Alert 3 to obtain these temps, I don't know how accurate these are to begin with. If I start compiling something, in Worldcraft for example, which I think brings me to full system load, temps get to 140 F. (I'll have to switch to Celcius, I know, damn Americans) I have never had a lock-up, system crash, (well, I am running windows) or anything to make me suspect there is a temp problem. I just got a little concerned after reading some articles and posts here about tempratures in general. I am using the Arctic Silver, also using a slightly better than stock fan. Rellly waiting to get my new sink and fan, I'll update when I get it all switched out. Thanks again, Cya
