A fan frame includes a housing (), a supporting base () and a plurality of ribs () connecting the housing with the supporting base. One of the ribs includes a bottom wall (), and first and second lateral walls () extending from two opposite sides of the bottom wall, respectively. A receiving groove () is defined between the bottom wall and the lateral walls. A securing tab () extends from an outer end of the first lateral wall towards the second lateral wall. A securing finger () extends aslant from a free end of the tab towards the second lateral wall. A slot () is defined between the finger and the second lateral wall with a width thereof gradually decreased inwardly. The tab, the finger, the bottom wall and the first lateral wall cooperatively define a gap () therebetween for extension of power wires () of the fan.

A cooling fan includes a fan housing () having a central tube () extending upwardly therefrom; the central tube has a bottom, annular protrusion (). A bearing () is received in the central tube and mounted on the protrusion. A stator () is mounted around the central tube. A rotor () includes a shaft () having a free end () extending through the bearing and defining a notch () therein. A locking washer () engages into the notch of the shaft to limit movement of the shaft along an axial direction thereof. A balance structure () is arranged between the locking washer and the bearing. The balance structure is made of magnet and exerts a downwardly pulling force on the shaft to prevent the rotor from moving upwardly when the rotor is rotated.
