Even if the thurmo is stuck unles the fans are coming on at that low a temp it will still get hot at idle and not moving , turn the fans off and no thurmo and you will see it heat to boil

Sensor is my guess or big raid and early fans , Not sure what all he has or where he is getting the reading from if he cant datalog
