that doesn't look like a DC motor. It's a brushless motor.

Changing polarity shud work if its just a normal dc fan...
unless it is connected to a circuit board with ic n stuff...

most fans have diode so that it will not turn backwards.
u can try to remove the fan diode if it has one.
or simply turn the fan itself upside down to reverse the air flow direction.
