Systems and methods for absorbing acoustic noise generated by computer cabinet cooling fans are described herein. In one embodiment, an acoustic absorber for use with a fan carried by a computer cabinet in a room includes a first acoustic panel spaced apart from a second acoustic panel. The first acoustic panel is configured to be positioned proximate to an outlet of the fan and at least approximately parallel to a flow of cooling air discharging from the outlet. The second acoustic panel is also configured to be positioned proximate to the outlet of the fan and at least approximately parallel to the flow of cooling air discharging from the outlet. The first and second acoustic panels together form an opening configured to direct the flow of cooling air away from the fan outlet and into the surrounding room. In a further embodiment, the opening formed by the first and second acoustic panels can be configured to extend at least approximately 360 degrees around the fan.
