What about a little flat spinning disc with slots cut in it, to look like a
fan? The idea is to have the same proportions as the real fan blade, but
with no curvature on the "blades", such as a real fan would have. This
should reduce a LOT of the noise, since your spinning disc won't be
scooping up air and throwing it around like a real fan. 

Place a "pop screen" between this and the microphone, to further cut down
on swirling the air into the microphone. You can also mount the "fan"
(spoked disc) on the end of a rather longish shaft, and place the tiny
motor farther away from the microphone that way.

I would use a second pop filter between you and the spinning disc, if I
planned to sing into the contraption. The pop filters I'm thinking of here,
look like sheer nylon fabric stretched over a hoop, such as used in some
major recording studios in front of expensive condenser microphones.

If you experiment with such things long enough, you might even invent a
"Leslie Microphone", for recording purposes. It would sure be a LOT smaller
and lighter than a Leslie speaker.   :)
