A vented cover includes a pair of cross-flow ventilation ducts each including an acoustic noise reduction lining. The ducts are "cross-flow" in that they cross and bypass one another. The cover is affixed to an enclosure containing components of a computer system and abuts against a panel of the enclosure having an airflow aperture. An air moving device (AMD) passes air through the enclosure from the ducts if the cover is an intake cover, and/or into the ducts if the cover is an exhaust cover. The ducts increase the air path length, and the acoustic absorbing surface, thereby increasing acoustic attenuation. Airflow resistance is reduced by reducing surfaces perpendicular and close to the area where air enters and by reducing sharp turns in the ducts. The cover has a relatively thin depth because the ducts cross and bypass each other in a very space efficient manner.

What is claimed is: 1. A computer system, comprising: an electronic component package; an enclosure for containing the electronic component package, the enclosure including a front panel, a rear panel, a top panel, a bottom panel, and two side panels; an air moving device for passing air through the enclosure; a vented cover affixed to the enclosure and abutted against a selected one of the panels having an airflow aperture, the vented cover including a pair of cross-flow ventilation ducts, wherein one of the cross-flow ventilation ducts crosses the other of the cross-flow ventilation ducts, and wherein at least a portion of each of the cross-flow ventilation ducts includes an acoustic noise reduction lining, wherein the vented cover has a first cross-section in which the cross-flow ventilation ducts are generally triangular, a second cross-section in which the cross-flow ventilation ducts are generally rectangular, a third cross-section in which the cross-flow ventilation ducts are generally triangular, and wherein the second cross-section is between and parallel to the first and third cross-sections. 2. The computer system as recited in claim 1, wherein the cross-sectional area of each of the cross-flow ventilation ducts remains substantially constant throughout and between the first, second and third cross-sections. 3. A computer system, comprising: an electronic component package; an enclosure for containing the electronic component package, the enclosure including a front panel, a rear panel, a top panel, a bottom panel, and two side panels; an air moving device for passing air through the enclosure; a vented cover affixed to the enclosure and abutted against a selected one of the panels having an airflow aperture, the vented cover including a pair of cross-flow ventilation ducts, wherein one of the cross-flow ventilation ducts crosses the other of the cross-flow ventilation ducts, and wherein at least a portion of each of the cross-flow ventilation ducts includes an acoustic noise reduction lining, wherein a first one of the cross-flow ventilation ducts has an intake port that is generally coplanar with an intake port a second one of the cross-flow ventilation ducts, and wherein the first one of the cross-flow ventilation ducts has an exhaust aperture that is at an angle with respect to an exhaust aperture of the second one of the cross-flow ventilation ducts. 4. The computer system as recited in claim 3, wherein the exhaust aperture of the first one of the cross-flow ventilation ducts is generally triangular and the exhaust aperture of the second one of the cross-flow ventilation ducts is generally triangular and in a complementary orientation with respect to the generally triangular exhaust aperture of the first one of the cross-flow ventilation ducts. 5. A computer system, comprising: an electronic component package; an enclosure for containing the electronic component package, the enclosure including a front panel, a rear panel, a top panel, a bottom panel, and two side panels; an air moving device for passing air through the enclosure; a vented cover affixed to the enclosure and abutted against a selected one of the panels having an airflow aperture, the vented cover including a pair of cross-flow ventilation ducts, wherein one of the cross-flow ventilation ducts crosses the other of the cross-flow ventilation ducts, and wherein at least a portion of each of the cross-flow ventilation ducts includes an acoustic noise reduction lining, wherein a first one of the cross-flow ventilation ducts has an exhaust port that is generally coplanar with an exhaust port a second one of the cross-flow ventilation ducts, and wherein the first one of the cross-flow ventilation ducts has an intake aperture that is at an angle with respect to an intake aperture of the second one of the cross-flow ventilation ducts. 6. The computer system as recited in claim 5, wherein the intake aperture of the first one of the cross-flow ventilation ducts is generally triangular and the intake aperture of the second one of the cross-flow ventilation ducts is generally triangular and in a complementary orientation with respect to the generally triangular intake aperture of the first one of the cross-flow ventilation ducts.
