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.
