Interesting and useful information. Not sure if/how we can use that to write
an actual driver for it; fan control on the chip seems to be handled outside
the NCT chip.=20

Copying the mailing list for input.

You set the desired limits in /etc/sensors3.conf and then execute "sensors =
-s"
to write the limits into the device.
