Did you read the suggested steps?

Mmm, does not look good.
You can try to load the latest SystemRescueCD (a livecd) which has the
latest version for "lm-sensors" package. If running "sensors-detect"
there either works, then... dunno :-/

Ouch :-(

Thermal zones are "points" defined to "ring the bell" (getting an alarm
and provide an event → i.e., activating or speeding up the fan) to avoid
overheating, but provided that your ACPI detection is not very accurate,
I won't take that values very seriously.

Yes :-(
