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?

It is going to depend on the type of motor used in the fan.

Don't try a light "dimmer". They are not designed for motor control.

Is it direct drive, or belt driven? If belt driven, you could change pulley
sizes to change the speed.
