Did you even took the time to read the entire thread, or what ?
I know what TAT and CoreTemp read, and what Speedfan and Probe II. And, by the way, you're wrong. Probe reads from the thermal diode under the IHS, in
the cpu. The C2D has both the DTSs in the cores and
the classical thermal diode under the IHS. PECI uses the DTS values to determine the required fan speed (that is, if you're using the stock heatsink/fan).
And yeah, it's quite expectable for the thermal diode reading to be lower than the DTS, except that it wasn't for me before enabling PECI in the bios, in fact, it was almost ten degree higher
. The problem here is that PECI shouldn't have anything to do with the thermal diode readings, espacially considering that I'm not using the stock hs/fan...
