I have a desktop installed under a desk in a wall unit. We are going to cut two ventilation openings to enable convection circulation. I would like to put a small fan inside the case to blow air out (and pull cooler air in). And I would like to have the fan turn on and off with the computer.
Is there any sort of fan that could draw its power from a USB 2.0 connection? Since the USB 2.0 can charge an iPod or Blackberry, I should be able to cut the end off of a USB 2.0 cable, solder on a connector, and then connect a box fan. I will make sure that the fan matches the voltage of the USB 2.0
I have several internal fan kits that cool hard drives. I would use one of those fans.
I would rather not run a wire into the case.
