Do that with caution.  Static can fry things, you want to be sure you
don't blast air across the electronics.

I'm told you don't want to whiz the fan around with air flow, either, it
can act as a dynamo and generate electricity into the circuitry
controlling it.  Hold it in place with something, so it can't spin.

Though I can't say I've been able to detect a problem when I
deliberately did that to a PSU fan until it made noises like a
fairground siren.  ;-)  I'll have to put a meter on the fan and see if
it really does generate any power while spinning.  I've yet to come
across a fan that will spin backwards if plugged in the other way, I
suspect there's a diode inside them.
