In-Line Fan Resistor

Using the in-line fan resistor can reduce the noise and vibration generated by PC cooling fans significantly.

However, using the resistor will drop the voltage to the fan to approx. 7.5VDC (commonly called 'under-volting').

3-pin in-line resistor for running PC fans quietly.

This will also reduce the power consumption, the rate of spin (RPM), the static pressure generated by the fan, and therefore the airflow.
