The fans are controllable through command line. There's a Python script for it out there somewhere.If you do wind up getting an SA120, make sure to get a 2nd p/s so that the fans will slow down. Makes a huge difference. You can get the higher wattage p/s for much cheaper that works just fine.

Unfortunately the days of cheap SA120's seems to be over.
