How to Change the Direction on DC Fans
- 1). Disconnect the fan's wires from the power wires. Remove the DC fan from the electronic device and lay the DC fan on a flat, clean surface.
- 2). Connect the positive wire on the DC fan to the negative power wire on the electronic device. Connect the negative wire on the fan to the positive power wire on the device.
- 3). Replace the DC fan to the electrical device the opposite way that you remove it. Turn the electrical device on and the fan will blow in the opposite direction.
