description The utility model relates to the technical field of fans, in particular to a light-weight noise reduction fan which comprises a support body, a cooling fan, a light-weight structure used for reducing the weight of the cooling fan and a noise reduction structure used for reducing noise of the cooling fan, and the cooling fan comprises a rotating body rotatably installed on the support body and fan blades fixedly arranged on the rotating body. The fan blade is provided with a cavity used for reducing the weight of the fan blade, and the lightweight structure comprises the cavity. The noise reduction structure comprises noise reduction grooves formed in the fan blades and noise reduction bosses arranged on the fan blades, and the noise reduction grooves and the noise reduction bosses are both used for reducing noise generated by the vortex. According to the cooling fan, the fan blades are of a cavity light-weight structural design, so that the overall weight of the cooling fan is reduced, the light-weight coolin
