Ok i have a strange question ( i think ) if you take a fan and change the 12volt and ground wires over, presuming its safe ( dont see why it wouldnt be in thie case, as it just makes an electromagnet? ) - this would cause the blades to spin the other way? BUT would this give the same CFM levels in the other direction? i ask because i want the fans to point the other way, but blow the oposite way - hope this makes sence!
thanks for any help
