Description of the Invention: [Technical Field of the Invention] [_] The present invention relates to a fan module, and more particularly to a fan module provided with a temperature sensor. [Prior Art] [0002] With the continuous development of computer hardware technology, a considerable part of the hardware operating frequency is getting higher and higher, so that the temperature inside the computer case rises faster and faster, if the heat cannot be taken away in time It will have a serious impact on the entire hardware system, and even lead to hardware burnout. In general, there are CPUs (Central Processing Units) fans and power supply fans in the computer chassis to accelerate the air flow inside the chassis. This reduces the temperature of the CPU and other components. The faster the fan speed, the better the heat dissipation effect. However, based on the energy consumption and noise factors, if the fan speed can be appropriately reduced, the power consumption of the system can be saved, and the noise of the computer can be reduced. Therefore, it is especially necessary to control the rotational speed of the fan within an appropriate range. [〇〇〇3] The conventional fan speed control function basically senses the temperature of the fan by a temperature sensor mounted on the fan, and then adjusts the speed of the fan according to the temperature, thereby realizing the instantaneous fan speed. Control, but the structure of commonly used fixed temperature sensors is more complicated. SUMMARY OF THE INVENTION [0004] In view of the above, it is necessary to provide a fan module that can easily and conveniently fix a temperature sensor. [0005] A fan module includes a fan and a temperature sensor for sensing the temperature of the fan, and a shield is fixed to the fan.
