Abstract:
A multi-radial-zone varying blade density fan system includes a fan in a fan chassis including a plurality of fan blades. A first radial fan zone on the fan includes a first fan blade density provided by fan blades located in the first radial fan zone. A second radial fan zone on the fan is located adjacent the first radial fan zone and includes a second fan blade density that is greater than the first fan blade density and that is provided by fan blades located in the second radial fan zone. A third radial fan zone on the fan is located adjacent the second radial fan zone and includes a third fan blade density that is greater than the second fan blade density and that is provided by fan blades located in the third radial fan zone.
