Could my Motherboard/Cpu temp Sensors be broken?

[Erick Aguilar]

So I finally went away and upgraded my hardware from FM1 to FM2, the performance is great as stock. However, since I got an unlocked chip, I want to overclock it.

Before this I wanted to stress the CPU to be sure it would be stable in it's stock core with it's turbo functions and such.
However, there is something funny. I use OCCT for tests. It was reporting that the CPU temperature was 0C unless there is load.

HWMonitor which supposedly reads from the motherboard directly (and OCCT doesn't?) says that on -idle- the CPU sits around 35 which seems okay and accurate, but if I select another window it randomly jumps to to 46 or 57 whereas OCCT only jumps up to 6C.

So I begin the stress test. OCCT is reporting temperatures of 30 Celsius under load, but HWMonitor reports that the temperatures are 77C? That's too close to what the CPU maximum temperature is registered at by the software, Max temperature should be 80, however in comparison to my older APU I would prefer to keep it under 65. With realistic readings of course.

The heatsink is as warm as the case, and the air being pushed away by the heatsink fan is colder than the air expelled from the PSU.

Would this mean my sensors are shot? And do you believe it would be a good reason to either replace the motherboard OR CPU?

EDIT: While looking at the motherboard temperatures, there is a reading that fluctuates around 43-45 which would seem more adequate to the CPU, could it also be that monitoring programs still don't offer support for this chip? Or Could it be reading the chipset which is included within the CPU?

Generally the bios doesnt lie and software can/does

Try some other software too see if you get two programs to agree

It appears that the motherboard included software to read temperatures, which is peculiarly called HW Monitor as well... I don't think CPUID and Gigabyte are the same company though. But Easy Tune lists that the CPU temperature is almost identical to that of HWmonitor's TPMIN2 reading. I suppose the other reading under the CPU section of the temp reading software is not correct in this case.

I tried various different softwares for monitoring and each one always had a reading that was odd/wrong. So i tried http://www.hwinfo.com/ and that has been the best so far (For me anyway).
You probably already know this but don't run 2 different softwares that monitor the same thing together as it cause's missreadings.
