A computing device having a housing; a temperature monitor to monitor a temperature within the housing; a cooling fluid drawing mechanism to draw cooling fluid into the housing; a cooling fluid drawing controller, when the computing device is installed within an enclosure as one of plural computing devices, to obtain a value representing the temperature, and if the value is within a predetermined range, to select an operating state for the mechanism from among a first state in which the mechanism draws fluid into the housing at a first rate, and a second state in which the mechanism draws cooling fluid into the housing at a second rate lower than the first rate, and to run the mechanism in the selected state; where the selection of the state is based on demand for cooling from other computing devices from among the plurality of computing devices.
