Abstract: Disclosed are systems and methods for independently cooling each of a plurality of zones of a computer system in relation to their respective zone power consumptions. The power consumption of heat-generating devices is monitored at each of a plurality of zones of a computer system. The cooling fluid flow rate to each zone is independently controlled. When an increase in power consumption is detected in a zone, the cooling fluid flow rate to that is increased in response. The temperature of each zone may also be monitored and the cooling fluid flow rate increased to stop the temperature rising above a present temperature.

Abstract: Disclosed is a heat sink with a set of fins that can be positioned in a plurality of orientations relative to a heat-generating electronic component to which the heat sink is thermally coupled. The heat sink has a base engaged with a rotary member with the fins. A drive member is coupled to the rotary member to rotate the rotary member relative to the base in response to a control signal. The drive member may engage the rotary member via a gear. The heat sink may have a temperature sensor coupled to the base and a controller. The controller may generate the control signal to the minimise the temperature of the base by aligning the fins with the airflow. The drive member may be an electric motor.
