My friend has a palamino XP 2000+ on a A7V266-E mobo with the stock HSF. The problem is the CPU temp is always at around 60C at idle and at full load shoots up to 71-72C. We underclocked the CPU to run at equivalent to 1800+, still the temp wudnt come down. Even though the Vcore is set at 1.6V in the BIOS, the ASUS Probe shows it to be 1.86V. Is this the cause for the over-heating temp? And is the Power Supply Unit the culprit for this over voltage?
