I have a temperature display. Its one that connects via a 4-pin molex. Where is the best place to put the thermometer part to get cpu readings? I currently have it slightly wedged in between my cpu and heatsink. Should I put it in between them more? Or a different place because of the contact between the cpu and heatsink?

Asking because the temperatures between CoreTemp and the temperature display are about 15C different.

Thank you :)
 
shounds about right, coretemp is reading the temperature in the DIE of the processor cores which will be hotter than the socket temp or I would imagine the heatspreader
 
First off don't put it in between the cpu and heatsink. That will ruin your contact and then the temps. The correct way is to mill a tiny channel in the IHS. Not very practical I know. The best you can do is epoxy it as near as possible to cpu on the heatsink copper. And the temperature on the IHS called Tc or case temp is meant to be higher than the temperature inside the chip called Tj tjunction, referred to as core temp. So thats expected.
 
For reading temps I would just use coretemp :) rather than faff around with a sensor :)
Probes have their uses for verification. Coretemp isn't that accurate from chip to chip. It uses the same assumed base Tjunction value for each delta calculation. Unfortunately the actual thermal activation point TCC is an unknown and factory set for each chip. What is accurate is the delta value to the TCC point.
