This is all very interesting theoretical stuff, but I'm not seeing what relevance it has to making RealTemp, which only reads the DTS info from the chip and doesn't read temps at all, more accurate in reporting the actual chip temperature. Other than at low-end calibration, how does any of this information or speculation help? Is it changing the top point of the graph in any meaningful way?

I thought the only practical value of note was the TjMax one, which is what RealTemp uses to convert the DTS to a temp reading. How is Tcase or anything else useful? Once I've put a heatsink on my chip, I don't give a flying f* what temperature the IHS or the heatsink is at, as long as it's keeping the processor cool...

I'm just wondering how this information will help us get a better value for TjMax? Short of us all drilling holes in our CPUs to calibrate each one accurately, I thought we were all stuck with the +/-20 degree inaccuracy inherent in these sensors and in the original per-chip Intel calibration. To a casual onlooker, it seems we are pretty much back to square one right now, to what unclewebb was saying about a year ago in threads here, that the only useful info is the DTS reported distance from TjMax and that as long as you're not throttling you shouldn't really care too much.
