Problems solved by technology

If it is divided linearly, there will be two possible results. One is that the fan noise is very small, but even if the temperature reaches the upper limit, the fan cannot adjust the maximum speed, and the temperature will exceed the range.
The second is that the fan can be adjusted to the maximum speed when the temperature reaches the upper limit, but the fan noise is too loud at room temperature
[0008] In short, the existing fan speed control method causes the fan speed to change unevenly, and the balance management of noise and heat dissipation is not ideal

Abstract

The invention provides a fan speed control method and device and a server. The fan speed control method comprises the steps of acquiring the temperature at the current moment; acquiring the fan speedtarget value corresponding to the temperature at the current moment; and adjusting the fan speed at the current moment according to the fan speed target value corresponding to the temperature at the current moment and the fan speed at the last moment. Through the fan speed control method, balance control over heat dissipation and noise of a fan can be realized, the basic heat dissipation effect isensured, and the noise can be minimized and stabilized as well.

Description

technical field [0001] The present invention relates to the technical field of server heat dissipation, in particular to a fan speed control method, device and server. Background technique [0002] In order to improve the heat dissipation capacity of ordinary servers, high-power and high-speed fans are usually used for heat dissipation, which also brings about the problem of huge noise. In order to reduce the impact of noise, server manufacturers have introduced PWM (Pulse Width Modulation, pulse width modulation) speed-regulating fan technology to adjust the fan speed through PWM waves. [0003] Currently, there are two ways to adjust fan speed based on temperature: [0004] Method 1: Divide the temperature into several intervals, each interval corresponds to a speed, the system reads the temperature regularly, when the temperature changes, look up the table to get the corresponding speed, and adjust it. [0005] Method 2: The temperature and the fan speed are equally div...
