    Be careful when connecting a motor/fan to the power from a USB port. It could blow out your USB port. To make it more safe, connect another USB plug to the fan in parallel so it can draw enough current to safely power the motor/fan.

    Well, a fan will draw quite a bit of current. If you are not careful, it could make your USB port break from trying to draw more current than available. Although, you would probably be okay as long as you put a diode across the power wires (black and red) like the schematic shown:
