I have a couple of small 60mm 12V fans. I'll call them blowers as they function a bit differently. The intage is from either side of the fan fan blades (parallel to the motor shaft) and the air flow is through a single port that is perpendicular to the fan blades. It works fine in this capacity. However, I was hoping to reverse this operation, pulling the air from the single port and blowing it out of the former intake. Just reverse the source polarity, right? Wrong. It doesn't run!
But why? Could there be an internal diode or something inhibiting reverse polarity operation? What is your take?
The fan has only two wires, red and black.
Thanks
