No, it just makes it two 100w CFL's...

And the pc fan is simple wiring. If it's non-polar then you can use any 2 prong extension cord and just wire the wires together. If it's polar, the fan will still spin but maybe the wrong way. If that happens, just switch the wires.

Good luck!

Just cut the extension cord's insert or the cell phone's adapter part off and expose the copper wires, then use the copper wires from your pc fan and tie them together. Simple stuff.

Click to expand...

If your fan is 12V, which most are, then it will be enough to power it... just not at full speed. I tried using a 5v cell charger and barely got half speed on a 12v fan, however, I'm now powering two 12v fans with a 15v transformer and they are running at full blast.

As for the wiring, just use red and black.

i think the yellow was a wire for a switch of some sort but yea my fans had a yellow wire too but all i did was pull the whole wire out and only used the black (ground) and red (power)
