1. A computing system comprising:
a chassis comprising a base and a pair of walls coupled to a peripheral side of the base;
a plurality of rotational drives disposed in the chassis;
an acoustic absorber frame comprising:
a frame comprising a support sheet, a pair of support walls spaced apart from each other and extending from the support sheet along a longitudinal direction of the chassis, and a plurality of first openings formed in the support sheet, wherein the support sheet is disposed perpendicular to a coolant air flow direction and coupled to the pair of walls; and
a first acoustic absorber comprising an acoustic material and a plurality of second openings formed in the acoustic material, wherein the first acoustic absorber is non-removably attached to the frame such that the acoustic material extends along a lateral direction of the chassis and covers an upstream surface of the support sheet, and each second opening is concentrically aligned with a respective first opening; and
a plurality of fans disposed downstream relative to the acoustic absorber frame, wherein the pair of support walls is coupled to a fan cage of the plurality of fans via a pair of fasteners such that the acoustic absorber frame supports and holds the plurality of fans,
wherein each fan is aligned with respective first and second openings, to draw the coolant air via a panel of the chassis to cool the plurality of rotational drives, and wherein the acoustic material absorbs a portion of reflected airborne noise from the plurality of rotational drives.
