TUAW reader and Flickr user sninesix posted this snapshot of the USB CPU fan he rigged up to cool his PowerBook. When the original fan died, sninesix found an old fan he had lying around, removed the wires and hacked a USB cable onto it.

He then removed laptop's keyboard and positioned the fan just above the CPU. With a USB keyboard connected, he was back in business. Well done! You can watch a video explanation here.

If you'd like to see your own rig featured here, simply upload photos into our group Flickr pool. Each Sunday we'll comb through the most recent entries and declare a "Rig of the Week!"
