Strange temp readings.

I was using core temp to watch the heat of my new processor, 17-18 degrees at idle, all normal.
Then I decided to push the CPU to see its max heat, 40 degrees aprox, it was good (For a Stock cooler w/ reduced speed to avoid too much noise)... At the begining.

That's when things went a bit crazy, as soon as the temp passed 40°, it made a jump to 200° and slowley returned to normal.
I decided to use Aida to get a more accurate reading and I noticed that while the CPU temp behaves normally, the core temps are the ones that shows that strange spike.
Also, I've noticed that SpeedFan doesn't seem to find the temp and fan of my processor.

My Pc doesn't shut down or loses performance when this happen, in fact, if it weren't for Core Temp showing the max temp reached, I wouldn't have noticed the change.

I believe that my mobo's heat sensor is busted (After all, I plan to change it since it's not a good one), but I want to see others opinions.

Hardware in question:
- AMD FX-8350 (Stock cooler).
- MSI 760GM-P23.

AMD core temps are only an approximation and at temps below 40, they aren't accurate at all, hence the 17 degree temp. That's probably below ambient and that doesn't happen with stock cooler, or peltier cooling or other stuff. After 40 is when they start to get better and more accurate.

Now with AMD chips there is 2 temps, the core temp, or package temp, and the socket temp, or motherboard temp. the core temp max is 62, socket temp is 72.

download openhardware monitor, hwinfo64, cpuid hardware monitor and try those and see which one gives the better idea of your actual temps.

Actually, it's not below ambient:
I'm freezing my butt right now :D

Now that you mention, I haven't seen Openhardware doing it, I'll reinstall it and see if that's the case.

EDIT:
OH did the trick, accurate info with no crazy spikes... Thanks!
