While running the Prime95 Torture test for max heat and power consumption, the CPUTIN gets as high as 83 C according to HW Monitor, while the hotter of my two cores only gets to a max of 75 C (the other is a max of 66 C). I read online that CPUTIN is the temp of the surface of the CPU itself that touches the cooler. So ASUS Probe and RealTemp/CoreTemp measure two different values. No wonder there are some discrepancies between the two.
Correct. And, IMO, the temperature that ASUS Probe is measuring (which is a motherboard temp sensor in the CPU socket) is much more accurate. I have always gone by this temperature because I feel it's the most realistic. In testing, it has also proven to be most realistic as my OC generally fails Linx when temps get past 80C (as read by ASUS Probe), however, all the other temp programs supposedly reading "core temp" (which should be higher), were, in fact, about 6-10C lower.
The reason for the inaccuracy is that "core temps" are calculated
off distance to TJmax, a figure that, it is supposed, Intel often lies about. The TJmax sensor is also grossly inaccurate at anything more than a few degrees below its trip point (which in our case is waaaay up 105C), which makes this an inherently inaccurate way to measure temps. The temp probe on your board, however, is designed to read normal running temperatures and is also generally more accurate because it's designed for temperaturing monitoring over a range, not just as a thermal switch for one given temperature.
Hope that makes sense.
