Abstract: A computer system comprises a chassis, an electronic component disposed within the chassis, and a cooling fan that comprises a motor support fixed to a housing that is coupled to the chassis and a hub disposed within the housing. A plurality of blades extend radially from the hub. A motor is disposed within a motor enclosure formed by the motor support and the hub. The hub is rotatably coupled to the motor such that the plurality of blades generates a flow of air around the motor enclosure. The system comprises a motor cooler comprising a flow path through the motor enclosure, where the flow path has a first opening and a second opening, and where the second opening is disposed within an area of lowered downstream pressure so as to develop a differential pressure between the first and second openings and generate a flow of air through the motor enclosure.

Abstract: A modular computer system is provided. In one embodiment, the system includes a computer server having a first printed circuit assembly disposed within a first housing and an expansion connector. The computer server is configured to be coupled to a modular expansion unit via the expansion connector to convert the computer server from a base configuration to an expanded configuration. In various embodiments, the expanded configuration may provide additional processing power, additional memory, or the like. A method of assembling a modular computer system is also provided.

Abstract: A cooling fan comprises an outer housing. A motor support is fixed to the outer housing and a motor is mounted to the motor support. A hub is rotatably coupled to the motor and, with the motor support, forms a motor enclosure that substantially surrounds the motor. A plurality of blades extends radially from the hub and are arranged so as to generate a flow of air around the motor enclosure when the blades are rotated. The cooling fan also comprises a motor cooler comprising a flow path through the motor enclosure, wherein the flow path has a first opening and a second opening, wherein the second opening is disposed within an area of lowered downstream pressure so as to develop a differential pressure between the first and second openings and generate a flow of air through the motor enclosure as the motor operates.
