I see. The fan sensors block is disabled, which is why sensors-detect
doesn't pick it up...

Please look in your BIOS if there is any option to enable fan speed
monitoring and/or control. BTW, does the BIOS display any voltage,
temperature or fan speed data?
If you can't find a suitable option in your BIOS, we can try to
manually enable the fan sensors block. However, in most cases disabled
sensors block are disabled because they are effectively unused
(physically not wired on the board.) So there are good chances that
this will not lead us anywhere. Do you have any reason to believe that
fan speed can be monitored and/or controlled on this system in the
first place?
If you want to continue, I will need the output of the following
command:
isadump -k 0x55 0x2e 0x2f 0x0a
