I decided to do the case cooling that you wrote about. I bought the 12v blower today. I have a few questions though. Were did you get the device to down the voltageto 7v and name and model number would help to. Also how do you wire this thing. Do i connect the blower to a molex from like an old fan then plug it into my PSU? Also is a 300 watt PSU enough for this and 2HD 2CD and a duron 750 or do i need a bigger one?
