Abstract
Automated control is provided of rotational velocity of an air-moving device cooling an electronics subsystem of an electronics rack. The automated control includes: automatically responding to a failure event associated with the electronics subsystem of the rack by setting rotational velocity of the air-moving device to a first upper limit (RPM) above a normal operating limit; sensing motor temperature of a motor of the air-moving device; automatically increasing rotational velocity of the air-moving device to a second upper limit (RPM) if the sensed motor temperature is below a first predefined temperature threshold (T), wherein RPM>RPM; maintaining rotational velocity of the air-moving device at the second upper limit while the sensed motor temperature is below a second predefined temperature threshold (T), wherein T>T; and returning to normal operating rotational velocity of the air-moving device subsequent to servicing of the electronics rack responsive to the event.
