Intel has been using bits [22..16] of MSR 0x19C to store the DTS temperature data for all Core based processors including the mobile chips and even the early single Core chips.

As far as I know they started using the DTS sensor and 0x19C in the late P4 series but I don't have one of those ovens handy to confirm this. All my info comes from the publicly available Intel documentation:

13.5.5 On Die Digital Thermal Sensors

Now that we know how to get this information out of a Core processor and we know that CPU-Z is capable of reading the model specific registers (MSR), maybe someone could convince Franck Delattree, programmer of CPU-Z, to include a real time DTS reading on the main CPU page of his excellent program.

UnSeenSVK: Read post #730:
"Using the DTS to report idle temperatures has always resulted in readings that are too low at idle."
