Description

technical field

[0001] The invention relates to the computer field, in particular to a device and method for monitoring the state of a computer power supply fan. Background technique

[0002] In modern computer systems, the system power supply (Power Supply) provides the necessary power supply voltage for the computer system. The stability of the computer system is closely related to the stable operation of the power supply.

[0003] As an electrical device that directly converts alternating current into direct current, the power supply has a relatively large thermal efficiency, so the heat dissipation requirements of the power supply itself are also very high. The heat dissipation of the power supply is directly completed by the power supply fan. The power supply fan mainly meets the heat dissipation requirements of the power supply and also provides the cooling requirements of the system (such as: heat dissipation of the graphics card). Therefore, to some extent, whether...
