Naw, I have good airflow. It's just very CPU dependant. My 65nm Quad@4Ghz drains about 125 to 130A current, and that is 24/7 due to it crunching for WCG.
Now, your little 45nm Dualcore drains 40-50A at most - see the difference? ;)
Same goes for G0 Dualies.
Slap a Kentsfield in there, OC it that high and you'll be seeing that temp as well.
I still think 60C is impressive though, any other mobo would have died long since (actually, 2 Abit IX38 did...)
