Tjmax is the upper limit at which the CPU forces the throttling (AFAIK). The exact value varies between CPUs, in you case it should be 101ÂC; the DTS reports a negative value (or rather a positive margin) relative to TjMax, the driver converts it to an absolute temperature.

I should be :) For some desktop CPU the exact value for TjMax is not known and is assumed to be 100ÂC; in this case the driver emits a warning in the log.
