PC fans have electronics in them so reversing polarity would be like reversing polarity on LEDs- It won't work. (some times it might turn in the same way no matter what the polarity. this is a protection feature on some fans)

Umm, it doesn't matter which direction the fan is facing because you can just reverse the polarity of the wires.

If you reverse polarity your fan will also go reverse.

I meant fan, not motor. Sorry.

Hmm, weird because all of my motors go reverse then. Also no need to call me a fool and break the "be nice" policy, I may be wrong.
