you know that you can run a +12 volt and use the +5 volt for negative you get 7 volts right? that is if that is a computer power supply.

Don't do that on these power supplies: The 5 volt probably has little or no current sinking ability, so you're bound to mess things up if you connect it that way!

It can be done on a computer supply if you want to run a fan slowly, but thats entirely different as long as you have the computer connected: That will draw so much power from the +5 volt line that sinking the current from the fan is no problem.. the computer sinks that current, NOT the power supply.

Another video added. My friend lend me his HD camera and we made a small video with it running in the night.
