An impeller (16) of a fan assembly (10) moves air along a secondary flow path (36) when driven by a motor (14). The motor also drives a fan rotor (12) to move air along a primary flow path (24) of the fan assembly. Air moving along the primary flow path moves in a first direction (D P ). Air moving along the secondary flow path moves in a second direction (D S ) opposite the first direction. A fan shroud (44) communicates air used to cool the motor into the primary flow path of a fan assembly. The shroud communicates the air into the primary flow path so that the flow of air is at least partially aligned with air moving through the primary flow path of the fan assembly.
