also you can hook them up either way, red to remote and black to ground or black to ground or red to remote, only thing that will happen is it will spin the other direction. You should position them so you have 2 pushing and 2 pulling probably

If you connect a DC fan up backwards (black to +12V and red to Gnd) it will do ....... NOTHING, it won't spin. AC Fans will run backwards, which will still be useless becasue the blades are set a certain way. The way to decide whether a fan is a push or a pull is look for the arrows on plastic casing, one has the rotation direction and the other has air flow direction - mount the fan so that the arrow points in the direction you want the air to flow.

not thinking completely clear ATM, but this applies only to brushless fans because they do not have a commutator or armature.
