Abstract

The invention provides a method for flexibly adjusting rotating speed of a server fan. According to the method, switching between server control and manual control is achieved through a dial switch, the rotating speed of the fan can be adjusted and controlled in real time through the design of manual control and introduction of the process of manually adjusting the rotating speed of the fan, a large amount of code development and debugging tool preparation do not need to be additionally carried out, and when a BMC and a CPLD break down, or relevant firmware development is not perfect, or no relevant debugging tool exists, control over the rotating speed of the fan can be conveniently and rapidly achieved, code development pressure is shared, fan noise is reduced according to the using condition, power consumption is reduced, and stable system operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of server fan adjustment, in particular to a method for flexibly adjusting the rotation speed of a server fan. Background technique [0002] Servers are often loaded with electronic devices such as CPUs, network cards, hard disks, and GPUs. These devices not only consume a lot of power during operation, but also emit a lot of heat. If the server system cannot be cooled in time, various components will continue to operate at high temperatures, which will not only affect the life of components and system performance, but may also cause damage to components and bring unnecessary economic losses. [0003] Currently, fans are mostly used in servers for heat dissipation, and fans need to have different speeds in different system environments. Generally, the adjustment of the fan speed is based on the input PWM signal. PMW (Pulse Width Modulation), that is, pulse width modulation, a complete time period T1 of a P...
