摘要:
A method for cooling system components of information handling systems may include generating a first pulse width modulation (PWM) control signal for controlling at least one cooling fan configured to cool a system component, filtering the first PWM control signal, and applying the filtered first PWM control signal to the at least one cooling fan. The first PWM control signal may be used to control a component fan and then filtered to generate a filtered first PWM control signal used to control a system fan. The filtering of the control signal may include dampening the control signal such that the control signal is less responsive to temperature changes as the temperature nears a set temperature.
