 NOTE: There's a bug in the fan controller; if you enable automatic fan control it will forget any previously-set target despite it appearing to be set correctly (i.e. `cat /sys/class/hwmon/hwmon5/fan1_target` will display the correct value).
 When you disable automatic fan control, you will need to set the fan RPM again.
