Abstract
A fan structure includes a fan rack including an accommodation open chamber, a center base suspended at the center of the bottom side of the accommodation open chamber and a plurality of connection ribs radially connected between the center base and the inner perimeter of the fan rack, and a fan including a fan body made from a hard plastic or rubber material and rotatably mounted at the center base of the fan rack and a soundproofing molding made from a flexible plastic or rubber material and directly molded on the fan body. Thus, during rotation of the fan to induce currents of air, the flexible material property of the soundproofing molding reduces air resistance and wind noise.
