I just had a thought. M106 Sn where n = 0 to 255 normally sets the fan to the specified PWM value. How about M106 S-1 to set it to auto?

It cant be that hard to use the existing thermistor to trigger a switch/relay.
more investigation to do it think.

The problem I see with that approach is that the voltage at the non-ground end of the thermistor is very close to the +3.3V supply voltage at low temperatures. So you really need to have that voltage available to compare it with - and you definitely need it if you want to detect an open-circuit thermistor, which I think is a necessary safety precaution.
