Abstract

An impeller, fan assembly, and associated methods are shown. Selected configurations are shown that include a circumferential feature formed within a plate of an impeller and spaced apart from edges of the plate. A centrifugal fan impeller, comprising: a number of circular plates, including a back plate, and a ring shaped front plate; a number of blades coupled between the back plate and the front plate; and a circumferential feature formed within at least one of the plates and spaced apart from edges of the plate, the feature extending outward in a direction normal to a plane of the plate.
