About four months ago, I had an overheating issue with my PC. I narrowed it down to the three extra hard drives I installed which was causing more heat then what my box could get rid of in turn was overheating my CPU and shutting it down. So, I bought a better heatsink and fan, plus a new box with a 120mm intake fan and two exhaust fans 1 - 120mm and 1 - 140mm. It seemed to solve the problem with having a max running temp of around 65C with a max load. Now four months later with no issues my tower gets knocked over and now my overheating issue is back. All fans seem to be running fine, I go into the cmos then to PC health to check the system temps and here are the read outs. CPU Temp - 28 C System Temp - 24 C CPU Fan - 2250 RPM Chipset Fan - 5625 RPM System Fan - 5625 RPM CPU Vcore - 1.42V Hyper Transport Vcore - 1.18V Memory Vcore - 2.65V Chipset Vcore - 1.47V +3.3V - 3.21V +5V - 5.08V +12V - 11.64V 5VSB(V) - 4.89V VBAT(V) - 2.83V I'm not sure what all of this means accept that after 7 minutes before the PC shutsdown the CPU Temp is 85 C and the System Temp is 30 C and this is all while I'm in just the cmos using no processing power. So, is my processor getting old and need a new one or maybe do I just need to clean the thermal grease off and put fresh on, or from the tower being knock over did the impact harm the CPU but it seems to work fine I can get far enough to login to windows. Any help would be appreciated. By the way the CPU is an AMD Athlon 64 3400+
try reseating your cpu heatsink fan assembly as it has been knocked slightly off the cpu causing an air gap between heatsink & cpu thereby causing your overheat problem.
The CPU should be ok; it is not a bare core like some of the older ones. Make sure that you put new thermal paste on while you are reseating the heatsink.
Thanks for the replies I put new thermal grease on and reseated the heatsink and that seemed to fix the problem. I overlooked that possibility, thinking it was something more serious. Thanks again
