The noise of a fan can be measured in decibels using a sound pressure level meter. Knowing the level of noise allows people to classify as pollution or conducive.
All fans will make a "whooshing noise" If there is a squeaking or grinding noise the fan motor needs to be replaced/refurbished.
CFM stands for cubic feet per minute. It's a measure of how much air the fan will move, but a higher CFM also means more noise.

replace the fan. They're cheap.
if fan make a loud noise your fan clutch is bad
grinding noise from the fan is a bad bearing on either the fan or the water pump.have it checked before it lets go and goes thru radiator
Change the blower fan speeds to see if the noise changes. It is possible that the fan is still running while the heat is off, and the fan is rubbing.
IT CAN BE CALLED ALSO AS HUMMING DUE TO INDUCTION OR POOR INSULATION. NOISE CAN BE MEASURE USING DECIBEL METER.
It may not be the fan making "more" noise when you turn on the lights. It may actually be the bulbs making noise. Incandescent bulbs when operating on a dimmer make a high pitched noise - it is the filament vibrating. Try just the lights without the fan and see if you hear anything.
