USB Powered Chassis Fan [Mod]

post #1 of 8
Thread Starter 
- USB powered chassis fan mod -

Requirements:
  • Soldering Iron
  • Solder
  • Wire Strippers (Something to strip wire)
  • Chassis Fan
  • USB Power Cord (I ripped mine out of an old mouse)
  • Heatshrink or Insulation tape

Instructions:
  1. Set your wires up so that you have: Red and Black wired to the fan, Orange and Blue wired to the usb. If you have any other wires attached to the USB or fan cut them off, It's important that you cut the data wires off the usb (Green and White)


    _____
  2. Cut two pieces of heatshrink roughly 4mm in length. Then put a piece on each wire before soldering.
    _________
  3. Strip all 4 wires so you can solder them together.
    __________
  4. Solder the following wires together: Red and Orange, Black and Blue. Red is your power, black is your ground if you didn't already know.
    _____
  5. Heat up the heatshrink over the wires to tidy things up.


Now just tidy things up, plug in the usb and your fan should spin up @ 5v.
Hope you found my first tutorial understandable and straight forward. Thanks ~Rowey

Use this in many different ways, but the best thing to do with it is strap it to a console and plug it into usb, therefore it drastically cools the console without voiding warranty.
There are also many more uses for this.


Thankyou to: shinji2k, for the reassurance.

My finished result:

The magenta one will be your V+ (connect that to the red wire) and blue will be ground (connect to black). The max current over USB is 0.5A but that shouldn't be a problem for a normal fan. It'll work provided the fan will spin up at 5V, many are not able to.

White and green are data.

i have done this many times, and several usb wires don't contain a blue wire, but rather a black one. i have seen this several times. great guide!

i can't even tell you how many times i have had somebody give me an old laptop cooler with no cord and i find a cord that fits and cut apart a usb to provide correct power. works every time

Haha, i just did this earlier, trying to fix my sisters mouse. But failed so i ripped it apart and wondered what i could power by usb, then i thought FANS! haha cheers for the feedback anyway! ~Rhys

Really the power wires are supposed to be black and red but it seems like some manufacturers just use whatever they can get. Sometimes you just have to use a multimeter to figure it out.
