Claim 9:
10. A method for cooling a computing device, comprising:
receiving, by a fan control system from at least one high temperature component temperature sensor that is included in a chassis, a first high temperature component temperature that exceeds a first high temperature component temperature threshold and that is associated with at least one high temperature component that is housed in the chassis, that is coupled to at least one heat dissipation device that is housed in the chassis by at least one heat transfer device, and that is configured to generate and transfer a first amount of heat to the at least one heat dissipation device via the at least one heat transfer device;
operating, by the fan control system at a first fan operating level in response to receiving the first high temperature component temperature that exceeds the first high temperature component temperature threshold, a first fan system that is included in the chassis and that is configured to generate a component cooling airflow past the at least one heat dissipation device and out of the chassis housing to dissipate the first amount of heat generated and transferred by the at least one high temperature component to the at least one heat dissipation device via the at least one heat transfer device and reduce the high temperature component temperature of the at least one high temperature component;
receiving, by the fan control system from the at least one high temperature component temperature sensor, a second high temperature component temperature that exceeds a second high temperature component temperature threshold that is associated with the at least one high temperature component and that is higher than the first high temperature component temperature threshold;
operating, by the fan control system at a second fan operating level that is higher than the first fan operating level in response to receiving the second high temperature component temperature that exceeds the second high temperature component temperature threshold, the first fan system;
receiving, by the fan control system from the at least one high temperature component temperature sensor, a third high temperature component temperature that exceeds a third high temperature component temperature threshold that is associated with the at least one high temperature component and that is higher than the second high temperature component temperature threshold;
determining, by the fan control system in response to receiving the third high temperature component temperature that exceeds the third high temperature component temperature threshold, that the second fan operating level for the first fan system is a maximum fan operating level for the first fan system; and
operating, by the fan control system in response to receiving the third high temperature component temperature that exceeds the third high temperature component temperature threshold and determining that the first fan system is operating at the maximum fan operating level for the first fan system, a second fan system that is included in the chassis and that is configured to generate a chassis surface cooling airflow into the chassis housing and through airflow apertures defined by the chassis that are sized to create a positive pressure volume in the chassis housing that operates to reduce the chassis surface temperature of the at least one chassis surface and dissipate a second amount of heat that is less than the first amount of heat and that is generated by at least one low temperature component that is included in the chassis housing and that is not coupled to the at least one heat dissipation device to reduce a low temperature component temperature of the at least one low temperature component.
