It means just what the message says: your Super-I/O chip is not
configured to monitor and control your fans. The pins are used for a
different functions.

Do you have any reason to believe that your fans are actually connected
to this chip?

Jean, hi,

Honestly speaking I have no other reference (e.g. Windows) than this
installation to see what the chip is capable of reporting.

I'm assuming that, besides FAN-speeds, it also monitors and reports voltage
levels, etc... But I couldn't find any datasheet to support those thoughts.

So probably that leaves me with a motherboard of which I cannot monitor
anything... Or do you have any other suggestions to get readings of, let's
say CPU core temperature, etc...

Kind regards,
