This works for some kinds of fans and not others. Foir AC
fans, you can just pick a slower fan or one with a lower
decibel rating.
Your best options are being able to compare airflow (cfm)
and noise level(db) ratings when selecting a fan.
Unfortunately, many sellers don't give specs for the fans
they sell. That's one reason I like to shop at Mouser.com
for fans.
