With the rapid development of technology and the Internet, large-scale integrated circuits such as servers tend to be highly integrated, and the operating frequency of components such as a central processing unit (CPU) and a hard disk array in a server is increased. The higher the speed, the higher the heat generated by the entire server chassis. If the heat in the server chassis is not exhausted in time, the accumulated heat will cause the devices or components in the system to fail to work properly due to continuous heating, and may even cause malfunction or damage to the device or component. In order to ensure the normal operation of the server, a cooling fan must be used and heat exchange through the air duct to discharge heat to the outside of the server chassis as soon as possible. However, how to control the operation of the cooling fan is the key to effective heat dissipation.

In order to improve the heat dissipation capability of the system, in addition to the temperature sensor in the heat sink, a temperature sensor is also installed in the appropriate position in the server chassis to measure the operating temperature of the heat source and the server. The difference or change in the internal ambient temperature is used to further control the speed of the cooling fan, thereby effectively improving the heat dissipation capability of the server chassis.
