The problem: So I built this system about a year ago and it ran fine except for some software issues about 11 months ago. Now i have a problem that has to be related to hardware. To put it simply the CPU is idling at 60C. I noticed it when Fallout NV started to lag randomly (run fine, then jump, then run fine again, every few seconds), and i had some issues with minecraft lagging after 5 minutes. So it has been happening for about a week now.
So i checked HWmonitor to see what my CPU temp was idling at. 60C. which is very high. The case temp was 32C though it was a hot day. When i checked in BIOS, it said 97C!! I understand that the BIOS temp will be higher due to the OS not having frequency scaling control. Though not that high right?
But here is the strange thing... When I was in BIOS i had the case open to check if the fans were spinning (They all spin) and i put my hand near the heatsink, and it did not feel that hot (not 97C hot)
it has stock heatsink and fan that came with CPU. No overclock on either the CPU or the GPU. And i cleaned the fans and heatsinks for CPU and GPU, with no change.
My question: Could it be caused by a faulty heat sensor? I dont know too much about such things so I wonder if it is a heat sensor what do i try to return, the CPU or the Motherboard or both? Could it be an issue with the thermal paste, though that does not deteriorate that fast, or at least it should not.
I just bought some thermal paste and I will reseat the heatsink. It is strange that the paste would fail after a year, the only computer I had that happen on was 10 years old and it sat in a closet for about a year. I will come back to post results.
Is Core Temp another utility for checking the sensors?
