A cooling system includes a primary heat sink including a primary top base plate, a primary bottom base plate and a primary fin pack including a plurality of fins, where the primary fin pack is disposed between the primary top base plate and the primary bottom base plate. The cooling system further includes secondary heat sink including a secondary top base plate, a secondary bottom base plate and a secondary fin pack including a plurality of fins, where the secondary fin pack is disposed between the secondary top base plate and the secondary bottom base plate. A heat pipe extends between the primary top base plate and the primary bottom base plate, where the heat pipe further extends from the primary heat sink and couples with the secondary heat sink.

An apparatus includes a housing, one or more storage drives, one or more fans, and one or more acoustic barriers. The housing includes a bottom side bounded by a front side, a back side, a first side, and a second side opposite the first side. The housing may further include a top cover removably attached to the housing. The storage drives may be disposed within the housing at a first location. The fans may be disposed within the housing at a second location spaced from the first location. The fans may generate a flow of air through the housing, while simultaneously generating sound waves that travel throughout the housing. The acoustic barriers may be disposed between the storage drives and the fans, and configured to attenuate the sounds waves prior to the sound waves reaching the storage drives in order to reduce the throughput performance degradation of the drives.

Attenuation of acoustic pressures in rackmount servers to reduce drive performance degradation

An expansion card bracket for a computer server has an expansion card support attachable to a motherboard and an expansion card accepting portion disposed near a top of the support. The expansion card accepting portion is configured to support an expansion card at an acute angle of inclination with respect to the motherboard. The acute angle of inclination is substantially equal to an angle of inclination of a connector for receiving the expansion card.

The present invention is a method and apparatus for unidirectional coolant flow control unit for pressurized cooling systems. The invention comprises a valve on a coolant flow control unit. The valve remains in the open position during normal function of the coolant flow control unit. If the coolant flow control unit fails, the valve closes. Thus, the cooling system performs better than prior art cooling systems in the event of a failure of one or more coolant flow control units. In one embodiment, multiple improved coolant flow control units can be implemented wherein a flow of coolant enters one side of the system and exits the other side. In the even of a failure, the closure of the valve is caused by the shifting pressure within the system, which forestalls the cooling problems associated with prior art redundant coolant control flow systems.
