Really? Surely, if a slight amount of additional hardware (think 1x transistor or Mosfet) was added to invert the drive signal to the fan and the PWM output signal inverted then the default (ie power down situation) would drive the fan off rather than to 100%. Speed control of the fan would remain operational "as-is"Firmware has little part to play when the power is off...
