My Athlon 64 3800+ (skt 939) keeps overheating. It has Cool N' Quiet enabled and Smart Fan. It's not overclocked and is on the standard Heatsink and TIM. I managed to catch EasyTune5 before it crashed and it says the fan had stopped and the CPU was up to 61°c. But when I turn it back on 5 mins later the fan is working and will carry on working for 15 mins, then it will crash again, then turn off. Is there any damage done to the CPU and how can I stop it happening? Dave EDIT: It's happened 3 times now!
