But the problem here is that temperatures are ridiculous and definitely not real. During OCCT stress test or wPrime 1024M run CPU package quickly reaches over 75C and soon I can see it dropping clock speed from 3.9GHz to 1.7GHz or at least it shows that. Even during idle, what software reports as CPU package is very high. I found this problem while I was monitoring PC with HwInfo64 software. What happens is that CPU is misreporting temperature. Unfortunately, if it isn't the heatsink, there is no easy user fix other than replacing the offending part.I'm having a weird CPU reporting problem with my computer.
If the readings are OK, I would suspect your processor, if they are off as well, then suspect the parts on the board. This can help point to where the problem lies. Try installing a different processor and see if the readings are still incorrect. It is possible for these temperature sensors to fail although I haven't seen it personally.
Ran the stress test and it went up to 94 degrees before being 100% throttled. After powering it up, there was no noticeable change in the temp - ideling at 74. I polished the surface, re-applied some new paste, and reseated the heat sink. I removed the heatsink and cleaned off the original thermal paste (which was somewhat crusty). So that leads me to believe it's a CPU seating issue (even though I used thermal paste to seat it two years ago when I built the machine)
Is there such a thing as a CPU temp sensor showing the wrong readings? To top it off, I removed the cover of the box and felt the cpu heatsink and it wasn't even warm. System remains stable though.įor over a year now, my CPU has run very cool (40's) with a large commercial copper heatsink/fan that I bought separately.
When I stress-test the machine, the temp goes up to 91 degrees and the CPU actually throttles. Everest Ultimate is suddenly telling me that the CPU temperature (and core temps) for my E6850 Core 2 Duo is 72 degrees Celsius.
