On the electronic component 82. The fan 30 includes a square frame 31 and an impeller 32 received in the frame 31. The square frame 31 is evenly provided with four through holes 31 at four corners for the fasteners 36 to pass through. Referring to FIG. 2, the fan fasteners 2A each include a rectangular sheet-shaped body 22'. Two opposite sides of the body 22 extend perpendicularly to two hook pieces 227, and the body 22 is adjacent to the hook piece 227. A square lug 223 and a square fixing piece 225 are spaced apart from each other. The lug 223 extends horizontally from the edge of the body 22. There is no circular boss 224 thereon. The center of the boss 224 is provided through the boss 224. And a fastening hole 226 of the lug 223; the fixing piece 225 extends vertically downward from the edge of the body 22, and a through hole 228 is defined therein.
