Using the --thermal flag, framework_tool reports appropriately three fan RPM values for the Framework Desktop, corresponding to the PWM inputs for APU fan, Sys1, and Sys2.

Issues are:

1. Fans aren't labelled, all three outputs just show up as 'Fan Speed'
2. If only the APU fan is plugged in, the RPM reading corresponds to the second readout, but if a fan is plugged into Sys1 then APU fan becomes first readout and the Sys1 fan becomes the second one. This behaviour is a potential source of confusion / error. I don't have a fan to put into Sys2 so I don't know what the behaviour will be if that slot is occupied.
3. The --autofanctrl flag resets all of the fans. There is no way to only reset a single fan.

I imagine these are novel issues as the average laptop user doesn't tend to have to worry about multiple fans, but I'd be grateful if they could be looked at.
