I just checked my CPU temperature using Abit uGuru and it's running at around 60 degrees Celsius at idle! I've got a Q6600 with a Thermalright Ultra 120 Extreme and a 120mm fan. It used to be around 27 degrees at idle, so obviously something is wrong.
I need ideas for troubleshooting this. Is it likely to be that the heatsink is not making good contact with the CPU heatspreader? The Ultra 120 Extreme is an extremely heavy heatsink and i've always been concerned that the wieght of it would prize it away from the CPU do to the motherboard being vertical and the HSF being horizontal in the case.
