I need a little help with my dimmer switch

[Beeblebrox.420]

my method works just fine with a bathroom exaust fan or any other 120v ac fan.

Yes, but he's using two 12 VDC computer fans. A solid-state AC motor control is not going to work for DC induction motors.

no thats when you get a fan controll for a car and just use that. they are made for 12 volt dc current and will only give 3 settings. I just think it is easier, cheaper and better and safer using 120 volt ac stuff.

I've decided to just go with a controller intended for computers, since i am trying to do this with computer fans anyway. Great feedback though, thanks

well I will bet just a straight up normal dimmer like mine will work for your 12v fans too. it will limit current for you. just hook your red wire to one of the blacks on the dimmer and the other black to your motors and the green dont worry about. are you using a pc power supply? it would prolly be safer than a wall wart.

radio shack also has wall warts with adjustable voltages that would work also
