ON. This is a very important point. Since that the G90 spin detection hardware
is sometime lacking of the SilenX mis-rotation signal detection, this could let
the unit running while the blade is stopped by the 'miss-cut' front plastic part

That's it! The fans should all run fine when the unit is powered up. The big
difference being how G90 is now even quieter than before (-7dBA) Enjoy!
