The appropriate file is:

Commenting coretemp out has no change.

Sensors produces the following output:

inxi -s produces the following:

fancontrol gets me the following:

Which brought me to sensors-detect to find the sensor at issue,
coretemp, and get the driver for that sensor loaded at startup in

But, adding that driver did nothing -- the sensors, inxi -s, and
fancontrol commands produce the same output as indicated above.

And, I cannot understand why a recovery boot has the fans running
normally but a regular boot has the fans running full speed. Any
explanations about the difference between the two kinds of boot?

take care,
