Problems solved by technology

Compared with the similar curve 1' specified by the CPU thermal energy data specification, the actual CPU temperature curve 1 is slightly higher than the curve 1' below Tcontrol when the power is constant, and when the CPU temperature exceeds Tcontrol, the fan has been running at full speed, So curve 1 is much lower than curve 1', causing excess power output and increased noise

Abstract

The invention discloses a control method for a server fan. The control method comprises the steps that the temperature and the current of a CPU are monitored; when the temperature of the CPU reaches a first threshold temperature value, a slope parameter in the power and temperature relation function is set to a first slope value; when the temperature of the CPU reaches a second threshold temperature value, the slope parameter is set according to the change amplitude of the current of the CPU; the operation power of the fan is determined according to the set slope parameter and the real-time temperature of the CPU; and the second threshold temperature value is larger than the first threshold temperature value, and when the real-time temperature of the CPU is the second threshold temperature value, the operation power, obtained according to the first slope value and the second threshold temperature value, of the fan is smaller than the maximum output power of the fan. The method can reduce noise and reduce power output. The invention further discloses a control device for the server fan and equipment and a computer readable storage medium which all have the technical effects.

Description

technical field [0001] The present application relates to the technical field of servers, and in particular to a method for controlling a server fan; it also relates to a control device, equipment and a computer-readable storage medium for a server fan. Background technique [0002] The temperature of the chassis increases with the temperature of the CPU. It is very important for the operation of the server to monitor and adjust the CPU temperature in time to reduce the temperature of the chassis to a safe standard. Currently used methods for fan control such as figure 1 As shown in the figure, Min represents the minimum output power of the fan, which is determined by the minimum voltage required to start the fan; Max represents the maximum output power of the fan, which is the power when the fan operates at full speed with the working voltage. Tambient is the temperature value when the fan starts to run, Tcontrol is the temperature value when the fan is required to run at ...
