To make the USB fan Just grab any usb cable. All usb connections carry 5 volts always. The idea of this mod is to use those 5 volts for something useful, to power a fan. Take a fan and any old usb able, obviously a cheap one not some $20(sucker must be written on your forehead to pay that much) monster cable or something. Actually that's how companies can get the highest profit cables cost less than a buck to make then it's flopped and your pay 10 dollars, but that's for another time. Next just go ahead and splice one of the ends off of the cable hopefully you should see the ground cable and a red and black cable at least, for a normal cable there should be for wires but some only have 2. A typical fan has three cables on it a molex fan might have 4. Look for the red and the black cables on both the fan and the usb connector. simply connect the red to red and the black to black. It's that easy! now just plug it in an the fan blades should spin. that's all look at the picture and you can see the one I made hooked up to the IBM P.O.S. Simply as clean up you could definitely put some heatshrink on it but that's optional as long as a complete circuit is always made it will be fine. :-)
