Título: (EN) Server fan regulation and control method effectively reducing device temperature margin and reducing cooling power consumption
(ZH) 一种有效减少器件温度余量降低散热功耗的服务器风扇调控方法
Resumen: front page image
(EN) 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.
