A system for protecting a hard disc drive (HDD) from acoustic energy in a chassis comprises a set of foam strips formed from acoustically absorptive material. Each foam strip has a thickness such that, when the HDD is installed in a chassis, the acoustically absorptive material is in a substantially uncompressed state. Foam strips are separated by an airflow path width, wherein two foam strips, a first surface of an HDD and a second surface form an airflow path. The second surface may be a surface of an adjacent HDD or a wall of the chassis. Each foam strip has a width and length configured for absorbing acoustic energy that would otherwise propagate through the airflow path.

An information handling system includes multiple hard disk drives, a central processing unit (CPU) and memory complex, a graphics processing unit (GPU) and input/output (I/O) complex, multiple cooling fans, and first and second airflow vanes. The cooling fans pull in airflow through the hard disk drives and push the airflow through both the CPU and memory complex and the GPU and I/O complex. The first and second airflow vanes are located between the hard disk drives and the cooling fans. The first and second vanes are in a first configuration when the information handling system is in a CPU and memory centric configuration, and in a second configuration when the information handling system is in a GPU and I/O centric configuration.

A fan carrier includes a fan mounting section, a connector mounting section, and a connecting section. The fan mounting section is placed in physical communication with a fan of an information handling system. The fan mounting section has both structural rigidity and vibration rigidity. The connector mounting section is placed in physical communication with a fan-side connector of the information handling system. The connector mounting section has structural rigidity to properly align the fan-side connector with a motherboard-side connector of the information handling system. The connecting section is in physical communication with and located in between the fan mounting section and the connector mounting section. The connecting section has structural rigidity and vibration flexibility, and the vibration flexibility reduces vibrations from the fan before the vibrations are transmitted to the fan-side connector.

A fan carrier is to be placed in physical communication with a fan-side connector of an information handling system. The fan carrier includes a plunger assembly and multiple isolators. The plunger assembly is biased toward an at-rest position. The plunger assembly is in physical communication with the fan-side connector when the plunger assembly is in a deformed position. The isolators are mounted on the fan carrier, and dampen vibration energy in the fan carrier and prevent the vibration energy from being transferred to the fan-side connector. The isolators enable the fan-side connector to float within the fan carrier.

A cooling system for cooling a set of components in a compute module and an array of storage devices in a storage module, the array of storage devices comprising rows and columns. The storage module is wider than the compute module to accommodate a larger backplane. The backplane has large vertical vent openings for accommodating connectors of storage devices connecting to the backplane. Pairs of divider walls positioned between adjacent columns of storage devices form large channels for increased airflow between columns of storage devices and reduced airflow between adjacent rows of storage devices. The design allows for increased cooling performance and reduced acoustic energy (noise).
