Indeed.

AMD CPU sensors are notoriously off, and even more so in low
temperature ranges. Do not see the above as 10.2°C but just as "there's
a lot of thermal margin up to the high limit" i.e. your CPU cooling is
very efficient.

I'd say it's not used indeed.

You can't, k10temp is a digital sensor inside the CPU, there's no type
to change.

> What about the temp1 and temp2 sensors on it87?

You can try putting some load on the CPU to see if any of these
correspond to the CPU temperature (it would rise faster.)

No idea. Some boards use multiplexing for that but I am not aware of
Asus doing that. There could be another chip for fan speed
monitoring/control on the board. Or the IT8721F chip is improperly
configured (after all the chip _does_ support up to 5 fans...)

Do you see all fan speeds in the BIOS? If you do, and go from the BIOS
to Linux directly (assuming the system support that), does it help?
