1. A self-cooling system, comprising:
a housing configured to enclose at least one rotating component configured to rotate relative to the housing, wherein the housing comprises:
at least one inlet bore; and
at least one exhaust bore, wherein the at least one exhaust bore is disposed radially outward from a radial position of the at least one inlet bore with respect to an axis of rotation of the at least one rotating component, and wherein the at least one inlet bore and the at least one exhaust bore are positioned to establish a pressure differential to circulate a fluid into the at least one inlet bore, through the housing, and out of the at least one exhaust bore;
wherein the self-cooling system does not comprise a dedicated fan or additional rotating component configured to drive the fluid into the at least one inlet bore, through the housing, and out of the at least one exhaust bore; and
wherein the at least one inlet bore and the at least one exhaust bore are disposed in an axial end of the housing with respect to the axis of rotation, and the at least one inlet bore and the at least one exhaust bore extend from an exterior of the housing to an interior of the housing.
