Abstract
Computing devices have fan speeds governing airflows through the computing devices. The rack has a maximum airflow associated with a cooling component for the rack. The computing devices transmit their current airflows. A sum of the current airflows is determined. Where the sum is greater than the maximum airflow, the fan speeds of one or more selected computing devices are decreased. The fan speeds of lower priority computing devices may be reduced before the fan speeds higher priority computing devices are reduced. Fan speed reduction may be achieved in a centralized manner, by employing a centralized management component, or in a decentralized manner, without employing a centralized management component.
