How To: Make a USB fan

Make a USB fan

If things are getting a bit stuffy at your desk, don't fret. A cool breeze is just a USB slot away. Watch this video to learn how to make a USB 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.

Step 2. Strip fan wires

Using wire cutters or a wire-insulation stripper, strip off a half-inch of the protective coating from the two wires.

Step 3. Strip USB cable

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.

Step 4. Strip red and black wires

Strip a half-inch of the protective coating from the red and black USB wires.

Step 5. Connect wires

Twist the exposed USB wires to the exposed wires from the computer fan – red to red, and black to black.

Step 6. Tape wires together

Wrap the two individual sets of connected wires separately in electrical tape. Then, tape and wrap both sets together to form one cable.

Step 7. Build stand

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.

Step 8. Install 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.

Step 9. Plug in fan

Adjust and angle the fan as desired and plug the USB cable into your computer. Ah, feel the refreshing breeze.

I LOVE THIS!!!!! will do nxt time i have free time

what I'm more interested in knowing is, if I connect 4 fans in either a 2x2 or 1x4 formation, bunch up the respective black and reds with the USB black and red, place each of the fans blades in the same start position (so that they all start in sync) and connect it to my laptop USB, would I face any problem like overload?

nice fan manufacture..............
