A first outlet opening (ot1) provided on a housing of the first fan can be located relative to a second outlet opening (ot2) provided on a housing of the second fan such that a flow pattern of the first fan overlaps at least partially with a flow pattern of the second fan when viewed from a direction of a rotation axis of an impeller of the first fan.
