Step 2Build a 50mm USB powered Fan
Here is a link to an instrucatable about building a usb fan.
http://www.instructables.com/id/USB-Desktop-Fan/
This is how I did it.
A 50mm usb fan will fit over these louver vents.
Make sure to use a usb plug with a 1" long protrusion from the device. Anything longer that that wont fit between the router and the cabinet. I found a retractable usb extension cord made by ZIP LINQ that works great.
Cut the plug from the fan and the female end from the usb plug. Make sure to cut the other two data wires at different lengths so they don't touch. It will cause problems if they touch. Also cut the foil and shielding wires back.
Before soldering the wires together slip one 3/16" full tube over all the wires and two 3/32" pieces of shrink tube over the small wires . Make sure to pull the tube back far enough so they don't start to shrink while soldering. Solder the red with the red and the black with the black. After soldering shrink the small tubes over the small wires soldered areas using a heat gun or even a lighter. Be careful not to burn or melt the wire sheathing and be sure to cover all the exposed wires. Then shrink the larger tube over all of them. This will make the wiring safer and better looking.
