It seems the fan parameters are incorrect, and have been copied from the Drive Bay fan (RPM, not present on rm31) of the legacy therm_pm72 driver. This patch changes the parameters to match the Slots fan (PWM) of therm_pm72. With the patch, slots-fan speed drops from 99% to 19% during normal use, and slots-temp settle to ~42'C.
