Further, the fan 1 is arranged on the fan support 2 to form an integrated structure. The fan support 2 is further provided with an NTC support 21, which is an integrated structure with the fan support 2, so as to realize modular installation and improve assembly efficiency. Further, one end of the NTC support 21 extends to an air inlet surface 11 of the fan 1, and an NTC element 3 is arranged on the one end of the NTC support 21. The NTC element 3 is used for detecting the ambient temperature of the air inlet surface 11 of the fan 1. Further, an air inlet of the fan 1 is arranged on the air inlet surface 11. The fan assembly proposed by the present application realizes fixed installation of the NTC element 3 by arranging the NTC element 3 on the NTC support 21 of the fan support 2, so as to improve assembly efficiency. By extending the NTC support 21 to the air inlet surface 11 of the fan 1, the NTC element 3 can accurately detect the ambient temperature of the air inlet surface of the fan, so as to express the ambient temperature of the air inlet of the fan, and avoid that the NTC element 3 cannot accurately detect the temperature of the air inlet surface of the fan due to the influence of the distance between the rear shell and the fan 1. The fan assembly proposed by the present application has a reasonable NTC element mounting structure, which can effectively improve the accuracy of the fan ambient temperature detection.
