A cooling fan with shapes, sizes, and placements of frame and supporting ribs tuned to reduce operational vibration and noise includes a fan frame, a supporting base, and a plurality of ribs. The fan frame includes a bottom plate and a sidewall connected to the bottom plate. The supporting base is formed at the bottom plate. The plurality of ribs extends from an outer circumferential surface of the supporting base to the sidewall. At least one of the plurality of ribs and the fan frame is asymmetrical with respect to the supporting base.
