Sensor and voltage readings are suspect unless verified.
That said,do also consider that thermistors are inherently tied to Vref .
The "on board"  Vregs also can compensate for incredible out of ranges
HIGH but not so much LOW being largely "linear" as opposed to Switchers.
Then also consider  Vcore being clock and duty cycle subjective in REAL
value as to it's impact. All this may tie into the rest of your situation.
