The A7V333 also reports the in-socket diode temperature and it typically sits at 10C higher than the CPU diode. Of course none of this stuff is calibrated properly, but it is good enough to pick up differences.

Compression would occur from resistance in the traces. Not uncommon if mobo mfgr crosses pcb layers or runs them too long. 0.4-0.8C per ohm for maxim ics; prolly similar for Asus. Shifting C/W numbers (not constant with watts) is symptomatic of trace lengths being longer than recommended by ic mfgr:

Would it surprise anyone if there were issues with an Asus onboard temp monitoring device?
