CPU temp reading

[dakingen]

Hi

The cpu temp reading in Freenas/Truenas seems to be wrong with my system on both 11.3 and 12.
It reports 87C with no cpu load. BIOS reports 54C and cpu stress with ultimate boot cd sensors reports 58C.

Cool & Quiet and C6 disabled in BIOS.

Any ideas on what might be wrong?
