Suppressing Acoustic Noise in PWM Fan Speed Control …
Fan speed control extends fan service life and decreases acoustic airflow noise and average fan cur-rent. The most efficient way to implement fan speed control is to use low frequency pulse width modulation (PWM). However, PWM fan speed control can some-times introduce unwanted acoustic noise at a fre-quency equal to that of the PWM itself. This is
