Therefore, the fan speed regulation scheme is provided, the running power consumption of the fan can be reduced, and the PUE of the system is reduced.
Referring to fig. 1, an embodiment of the present application discloses a method for regulating a speed of a fan, including:

After the first rotating speed is determined, the rotating speed of the fan is controlled by adjusting PWM (Pulse width modulation) output to the fan, so that the fan runs at the first rotating speed, and the working temperature of a system chip is ensured to be in a reasonable range. Of course, the number of fans can also be taken into account when determining the first rotational speed.
step S12: and judging whether the current system heat dissipation state meets a preset condition.
in a specific implementation manner, the present embodiment may determine whether the current environment temperature information meets a preset environment temperature condition, whether the current temperature information of the target component meets the preset target component temperature condition, and whether the current first rotation speed meets a preset rotation speed condition, if both the current temperature information and the current first rotation speed meet the preset rotation speed condition, it is determined that the current system heat dissipation state meets the preset condition, and if not, it is determined that the current system heat dissipation state does not meet the preset condition.

In a specific embodiment, if the second power consumption is less than or equal to the first power consumption, that is, the power consumption after turning off one fan is less than or equal to the power consumption when not turning off the fan, the process goes to step S12, that is, if the system heat dissipation condition is satisfied, the fan may still be turned off, and if the second power consumption is greater than the first power consumption, that is, the power consumption after turning off one fan is greater than the power consumption when not turning off the fan, the fan in a turned-off state is controlled to be turned on, and the process goes to step S11, and the fan is turned off when the system satisfies the system heat dissipation condition, so that the fans in the system can be operated at the lowest power consumption of the system by comparing the power consumptions of different numbers of fans at corresponding rotation speeds, thereby reducing the PUE of the system and improving the energy utilization rate.
