You can't just get a dimmer switch. You need something designed for AC motors.
I used this device from Amazon:

To control the speed of a bathroom vent fan that I use as a cooling fan for a closet full of computer stuff. It quieted the fan down and still maintains a good speed.
Worked really well for me.
If the motor is a shaded pole motor, which if it's a cheap fan it probably is, you can reduce the voltage to the motor to slow it. One solution is a light dimmer. You might find however that the fan may not turn on if the speed setting is low. You then up the speed, then lower it again.
A better solution is this one., or one like it.
A cheap and dirty alternative is to trim down the tips of the fan blades (in diameter) bit by bit until the noise is acceptable. Obviously reducing the fan effect, but also the noise.
