How To Make a USB Fan: Retrieve computer fan

Step 1: Retrieve computer fan

Look online or at your local computer-repair shop for a plastic computer-cooling fan. Or, dismantle an old computer and unscrew the fan inside. Disconnect the two wires that attach it to the computer – one red, one black. The wires will remain connected to the fan.

Cut off one end of the USB cable and strip away two inches of the outer casing. You should see four wires inside – green, white, red, and black. Slice off the green and white wires up to the casing. All you need are the red and black wires.

Create a stand for your fan. To start, get about 18 inches of sturdy electrical wire and bend it into a square “U” shape the same width as the fan.

A modified wire coat hanger can also serve as a suitable stand.

Push each end of the wire through the bottom screw holes in the fan. Bend and push the rest of the wire up, around the fan, and through the top screw holes. Bend the ends of the wire to secure the stand, and cut off any excess. Rest the stand on a flat surface.
