A heat dissipating fan includes a housing (201), a stator (21), a rotor (27) and a buffer structure. The housing defines an accommodating space (202) and includes a hollow tube (201b). The tube encloses first and second bearings (22, 23) therein. The stator is arranged in the accommodating space and around the tube. The rotor has a shaft rotatably disposed in the first and the second bearings. The buffer structure includes at least a pair of magnets (25, 26) received in the tube and located between the first and second bearings. Repellent force is generated between the magnets, thereby preventing at least one of the first and the second bearing from being damaged by an accidental force acting thereon.
