Abstract

The application discloses a method for controlling a fan speed. The method is applied to a server including a power supply unit, a first fan, and a second fan. The method includes: obtaining a first current control data and comparing the first current control data with a second current control data. A next-stage control data of the second fan is determined according to the first current control data and an increment if it is determined that the first current control data is greater than the second current control data. The second current control data is determined to be the next-stage control data if it is determined that the first current control data is less than or equal to the second current control data.

Dependent claims

A method for controlling a fan speed that is applied to an electronic device, the electronic device comprising at least one power supply unit, at least one first fan, and at least one second fan, the at least one first fan being configured to generate airflow passing through the electronic device, the at least one second fan being configured to generate airflow passing through the at least one power supply unit, a speed of the at least one first fan being controlled according to a first current control data, and a speed of the at least one second fan being controlled according to a second current control data, wherein the method comprises:

obtaining the first current control data and the second current control data;
comparing the first current control data with the second current control data;
determining a next-stage control data of the at least one second fan according to the first current control data and an increment if it is determined that the first current control data is greater than the second current control data;
and
determining the second current control data as the next-stage control data if it is determined that the first current control data is less than or equal to the second current control data.
