Abstract: A fan silencer module includes a housing having a first end of the housing, a second end of the housing, and an interior surface between the first end of the housing and the second end of the housing. Acoustic absorbing material is disposed on the interior surface. A honeycomb air flow director is disposed at the second end of the housing. And an electromagnetic interference gasket surrounds an outer edge of the honeycomb air flow director. In an embodiment, a depth of the electromagnetic interference gasket is at least as deep as a depth of the honeycomb air flow director. Also provided is a handle, and a latch actuator, to enable removal and replacement of the fan silencer module and an associated fan module from a chassis.

Abstract: Presented herein is a cold plate assembly including a sub-plate and a vapor chamber for use as part of a remote fin cooling system for an electronic device. The sub-plate includes a first surface, a second surface, and a plurality of pipes. The vapor chamber includes a first wall and a second wall opposite the first wall. The first wall and the second wall define an interior cavity having a first depth for one or more first portions of the vapor chamber and a second depth for one or more second portions of the vapor chamber. The second surface of the sub-plate is attached to the first wall of the vapor chamber.

Abstract: Aspects described herein include an apparatus comprising a receptacle comprising a cage dimensioned to receive a pluggable optical module into an interior volume, An opening is defined in an exterior surface of the cage. The apparatus further comprises a heat sink assembly rigidly attached to the cage. The heat sink assembly comprises a thermal interface material extending through the opening into the interior volume. The thermal interface material is configured to compress when the pluggable optical module is received into the interior volume and contacts the thermal interface material.
