Server fan regulation and control method effectively reducing device temperature margin and reducing cooling power consumption

Abstract

The invention provides a server fan regulation and control method effectively reducing device temperature margin and reducing cooling power consumption. The method comprises the steps that the component temperature is controlled through server working state detection and a novel fan regulation and control method, and the temperature of a server designed inlet air temperature sensor is read by determining linear changes of the device temperature along with the environment temperature through tests, so that the system fan rotating speed linearly changes along with the temperature linear changes. According to the server fan regulation and control method effectively reducing the device temperature margin and reducing the cooling power consumption, compared with the prior art, the system fan rotating speed linearly changes along with the environment temperature, the device temperature margin can be effectively reduced, and the fan power consumption is reduced; the control process is not affected by the external environment and load condition, and the cooling regulation and control effect is improved.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a server fan control method which can effectively reduce device temperature margin and reduce heat dissipation power consumption. Background technique [0002] The power consumption of the whole server is related to the temperature of the components and the power consumption of the fan. In order to reduce the power consumption of the whole server, today’s server products put forward higher requirements for the power consumption of each component. It is necessary to have a large temperature range of the internal components of the server to regulate the fan speed. Therefore, when the workload of the server is low, there is an excessive heat dissipation problem, which is manifested by a large margin between the actual temperature of the components and the temperature specification. As a result, the proportion of fan power consumption in the whole machine power consumption incre...

[0002] The power consumption of the whole server is related to the temperature of the components and the power consumption of the fan. In order to reduce the power consumption of the whole server, today’s server products put forward higher requirements for the power consumption of each component. It is necessary to have a large temperature range of the internal components of the server to regulate the fan speed. Therefore, when the workload of the server is low, there is an excessive heat dissipation problem, which is manifested by a large margin between the actual temperature of the components and the temperature specification. As a result, the proportion of fan power consumption in the whole machine power consumption increases at low load. In order to reduce the device temperature margin and reduce heat dissipation power consumption, we need a new way to regulate the fan. Through in-depth analysis, we have summarized an effective A server fan control method to reduce device temperature margin
