What to look for

Impeller

The shaped blades push air as the hub rotates. Blade geometry balances airflow, pressure and noise.

Frame and mounts

The square frame supports the motor and provides corner mounting points. Mounting stability helps limit vibration.

PWM connection

A four-pin fan connection carries power, ground, a speed signal and a control signal. PWM lets a compatible controller adjust fan speed.
