Abstract: A system may include one or more heat-generating components, a chassis for enclosing the one or more heat-generating components, and a variable-location air mover subsystem comprising at least one air mover, a transmission system for varying a position of the at least one air mover relative to the chassis, and a control system. The control system may be configured to, in response to a condition for activating the at least one air mover, activate the at least one air mover and cause the at least one air mover to move from a first position relative to the chassis to a second position relative to the chassis.
