Need a 40x40x10 3.3v 2 wire fan

The point is I didn't need to drop, I needed more.

The situation has changed though - somehow I misread the voltage from the rail and it's actually putting out 16v. I have NO idea how I read 3.2 before.

Anyway, I put in a 7805 voltage regulator that brought it down to 5v, but the fan still doesn't spin up for some reason, not sure why. It just jumps for a moment. I tried a larger 12v fan and it spins fine, so I'm just going to stop in at compusa and get a smaller 12v fan to fit.

The 5v fan tested ok, it spins on AA cells fine.
