Embodiments of the present invention provide for a noise-reducing blower structure in which a fan-housing is disposed on an expansion card and juxtaposed to a heat sink. The heat sink is disposed on the expansion card and resides within a rigid frame above a processing unit chip. A fan that circulates air is disposed on the expansion card within the fan-housing. A duct is disposed on the expansion card, covering the heat sink and the fan-housing, and the duct is mechanically separated from the fan-housing for reducing vibration noises. By placement of the fan next to the heat sink, and not on top of it, the fan can be made larger to thereby rotate at slower speeds.
