An improved structure and method for mounting a fan, particularly a miniature fan ( 3 ), in a supporting wall ( 4 ), both facilitates a mounting operation and minimizes noise conduction after the mounting operation. An elastomeric overcoat ( 1 ) at least partially surrounds the fan ( 3 ) and is preferably integrally formed with a plurality of mushroom-shaped mounting elements ( 7 ) adapted to engage in a corresponding plurality of mounting holes ( 41 ) formed in the supporting wall ( 4 ). Each mounting element has a shaft portion ( 71 ) and a head portion ( 72 ) with an internal channel ( 74 ) starting in the shaft portion ( 71 ) and ending in the head portion ( 72 ). Rapid mounting of the fan ( 3 ) to the wall ( 4 ) can be accomplished by inserting a respective tool ( 10 ) into the channel ( 74 ) of each mounting element ( 7 ), to elongate the mounting element and reduce its diameter, passing the elongated mounting element into its mounting hole ( 41 ), and withdrawing the tool, permitting elastic relaxation of the mounting element to restore its original diameter, thereby forming a sere, vibration-damping engagement with the periphery of the mounting hole.
