what are you doing with the fans???
just get yourself a 12VDC adapter... they are common with electronics, just read the plugs, it's the one used by time warner cable for their modems, and the motorola surfboard modems use them also
just plug the red into the red, black into black, and leave the yellow alone.... plug it in and it'll turn on....
and get some CFL's in there.... research LST and Screens to give you better yield
