Ok so i have this little cpu fan im going to use to vent my grow box, but i cant get it to work. It has 3 wires (black red white). I know the black is - and red is + but what doed the white do? Also, how can i get it to run ( ive hooked up red and black to a battery but it wontstart without the white)... Any help needed/wanted on this.
