Abstract:
1. An automated method for controlling the fan speed of computer system cooling fans with fluid density data from a centralized sensor comprising: determining a fluid density by a centralized sensor within an enclosed area, said enclosed area comprising a plurality of computer systems, wherein said centralized sensor is external to each of the computer systems, wherein each computer system configured to house at least one computer subsystem; conveying the determined fluid density to each of the computer systems which employs at least one cooling fan; in response to the conveying step, each of the computer systems selectively determining a need for adjusting a speed of the at least one cooling fan based on the determined fluid density; and when the need for an adjustment exists, each of the computer systems adjusting the speed of the at least one cooling fan in accordance with the fluid density.
