Suspect CPU temp sensor is wrong, how could you diagnose?

[gboucher]

CPU temps shows 90s from a cold boot at idle. Doesn't seem to change much not matter what is running (games). Pretty sure the cooler is mounted correctly, and strongly suspect the sensor is wrong. How would I go about finding out if this is the case?

 C or F?

 

You can fell the chip by touching the heatsink of back of board, 90c will fell buring hot.

 

Also check thermal paste and mounting pressure.

Good point, but if the heatsink is not contacting properly (but I thin kit is) it would be cool(er), wouldn't it?

Try on a another motherboard, cpu, or one of those temperature guns

good ideas, but i do not have any of those. (spare cpu, mobo, or temperature gun) This is for a PC i sold to some guy on kijiji (like craigs list in canada) Loves the PC, but is worried about the CPU temp, which is understandable, but I don't want to go to a lot of time or expense for this. I wonder what a mobo like this would cost. Would prob be the cheapest diagnostic solution.
