Summary:A method and apparatus for controlling fan speed are provided. The method obtains a first PWM value and a second PWM value of the fan based on the temperature of the server component respectively through a PID regulation algorithm and an open-loop control algorithm, and controls the fan speed based on the larger value of the first PWM value and the second PWM value.
