This universal power adapter I bought at the Depot for $12. This allows me to power the 'puter fans with a standard wall outlet via the adjustable power output on the front. Without it, the fan blows up. I know, I tried it already. What this does is decreases the power from the wall to the fan. A standard outlet is 15 - 20 amps, my 'puter fan only needs .12 amps.
