Go with a Taurus 2 speed fan or the Mark8 fan. You can find a Taurus fan for $30/$40 and any junkyard and they pull up to 3900 CFM on the high setting. Forget the Black Tragic/ Proform fan. They'll give it up on you. Couple the Taurus fan with a DCcontroler and your set. check them out. http://www.dccontrol.com/ They do sell fan controler combos, but it is cheaper to just find a fan in a junkyard. (A lot of old Taurus's out there. You'll be looking for a late 80's to early 90's model) If you have a Taurus or Mark 8 fan you would then use the FK-35 controler. This really is the best setup for the money.
