I have a gable fan that is very loud. I'd like to slow it down via a
rheostat/potentiometer. Is this possible? Is it advisable? If so,
can anyone suggest a rheostat that is adequate for the job?

TIA

Many fractional HP motors can be controlled by a rheostat, similar to a
light dimmer switch. Be sure you have one that can handle the HP of hte
motor.
