|Reducing noise from fan-cooled equipment|
|Keywords: Noise, Design, Fan|
|The ever-increasing power consumption of IT equipment, especially rack-scale datacenter and telecom equipment, is approaching a point of crisis. Significant amounts of cooling air flow are required, but the equipment form factor leads to air mover selections that are unnecessarily noisy. Other design constraints and early decisions conspire to further increase the noise output. A variety of coping strategies will be reviewed, along with their pros and cons and potential benefit. These will include overall design, fan selection, inlet flow management, lined ductwork, enclosures, and active noise control. Concepts for a form factor more amenable to high cooling flow and reduced noise will be discussed.|
