An on die reading will yeild about a 7-10C difference (hotter) than a compunurse touching the core. The reason is one is measuring the INSIDE of the core (on die) and one is measuring the outer surface of the core.

That's a good point, in many ways.
The original question here was about which one is more acurate: the mobo cpu temp probe, or the compunurse's probe right up against the core?
The compunurse is very easy to check for accuracy, with a glass of water.
Mobo CPU temp probes are not only located on a different area of the CPU than the core, but some mobos actually CALCULATE the core temp based on the reading of that probe, even though it's on the opposite side of the CPU, and is nowhere near the core.
The compunurses probe, as placed here, will measure the temp of th edge of the core, not the temp of the core itself.
So to answer the question, your mobo CPU probe is probably reflecting a temp that is closer to the real core temp, but is not very accurate in that, it may be off by maybe 2 or 3 degrees.
Your compunurse probe however is accurate to +/- 0.1 degrees, but it's not inside the core, and it's not right over the core, so it's probably reading something lower than the actual core temp.
As for the inside case temp, the compunurse is the clear winner here. The mobo probe is probably too close to other components to effectively give you an accurate temp.
