If you are using the "coretemp" sensor module, the logic by which it
reports "temperature" changed somewhere in the last few kernels. Also,
in many (most?) cases it doesn't report an actual temperature at all
but a relative one on a scale from 0-100 based on some operating range
defined by Intel? or somebody...
