You mean in the BIOS?

The National Semiconductor PC87360 Super-I/O chip only has 2 fan speed
monitoring inputs, not a full hardware monitoring block as the PC87365
and PC87366 have.

And nothing beyond EEPROMs on your SMBus.

The i2c-i801 driver seems to be well loaded, as seen in the i2cdetect
output above.

No, it is not. Apparently your hardware doesn't include hardware
monitoring features except for the 2 fan inputs on the PC87360. If the
chip is properly wired on the motherboard you may be able to also
control the speed of these fans, but that's about it.
