Ohh and btw theres differwnt sms coms i beleve. The expensive ones use a variac which controll the mains input voltage resulting is less ressonence. (Im a terrible speller)..... and the less expensive ones basicly swicth on and off your fans really fast in the ms. Whicth causes the fan to hum.
So to sum it up variac vased fan controllers are the best ones.
