Problems solved by technology

Due to the link delay between the fan speed increase and the CPU temperature change, when the system is pressurized from the idle state to 100% instantaneously, the fan speed cannot respond in a short time, and the CPU temperature may approach or reach the frequency reduction temperature. Heat dissipation risk

Abstract

The invention discloses a server fan operation control method. The server fan operation control method comprises the following steps: the maximum CPU power consumption Pidle of a server CPU in an idle state is obtained through testing; a temperature adjusting point T1 of a fan in a pressing state and a temperature adjusting point T2 of the fan in an idle state are set; the power consumption Pcpu of the server CPU is obtained; the magnitude relation between Pcpu and Pidle is judged; if Pcpu is higher than Pidle, a CPU control temperature T control is set as T1; and if Pcpu is not higher than Pidle, the CPU control temperature T control is set as T2. As two control points are set, on the basis of satisfying the system heat dissipation and power consumption demands, the CPU superheating risk caused by instant pressing is prevented, and the stable system operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electronic heat dissipation, in particular to a method for controlling the operation of a server fan. Background technique [0002] Relying on the advantages of high reliability, easy maintenance, and low cost, fan cooling has become the main heat dissipation method used by servers. During the working process of the server, the fan speed is not constant, but is adjusted by the environment and the temperature of internal components. The control logic of this fan speed becomes the fan control strategy. The fan control strategy must not only meet the heat dissipation requirements of the server in a steady state, but also ensure that the fan speed can respond in a timely manner to avoid system overheating when the system pressure changes instantaneously. In order to achieve the above purpose, it is necessary to set a reasonable control point for the CPU in the fan control strategy, that is, the target contro...
