which shuttle are you using? something doesnt add up. I have a Shuttle XPC SN95G5 with an A65 3500+ (using the ICE system). Idle temp is 31c on a cool day. 40c under regular usage and 50c after running doom 3 for a few hours. Whas is your fan settings? are you using the auto fan?, AMD Cool and Quiet ? Are you sure the heat sink is firmly mounted? My fan is running at ~1000rpm
