Thats really strange mr1c3man...

Looks like you've had a pretty good improvement, but those BIOS temps still look out of line (could very well be a bad sensor!)..

The one thing I don't see in the PIC is your IMC/NB_Vid, is it set really high,
Above 1.3v's? If so that can add alot of heat...

D'l the HWMonitor link I posted above and see what it says.

Double check everything, but it sounds like you've done all you can do...
I still find it hard to believe those temps can be right and you still have a stable system....

If the sensor's bad, you may just need to keep them as low as you can and try to ignore it...

I still find it hard to belive the chip would be stable at >65c under load or for that matter 57c Idle.

Do you have a DMM, or an IR Temp probe? If so check the CPU with that.
