Hi.
A big IF, but if you do have room for two of them I have found that =
wiring a
pair in series will reduce their speed and noise significantly with no =
Ill
side effects.  Alternatively a resistor in series (sufficient wattage) =
often
works well.  And if you put the resistor in the airflow it will reduce =
the
needed size somewhat.  I've used this trick on Yaesu FT-101 transceivers
where the TR relay was used to bypass the resistor when transmitting =
(full
speed) and the fan ran at slower speed when listening.=20

Is there a simple way to reduce the speed of a 115VAC
muffin fan so it runs about 1/2 its normal RPM?=20
