Abstract: Information handling system thermal conditions are controlled by hybrid interaction between a system thermal manager and a power supply thermal manager. The system thermal manager sets a speed for system cooling fans and for a power supply cooling fan. The power supply thermal manager determines a speed for the power supply cooling fan and also receives the speed for the power supply cooling fan determined by the system thermal manager. The power supply thermal manager commands the power supply fan to run at a selected of the determined speeds based upon one or predetermined conditions, such as by the selecting the greater of the determined speeds.

The processor is configured to determine a user-selected performance setting for the information handling system; determine a fan speed limit corresponding to the user selected performance setting; limit the speed of the cooling fan based on the determined fan speed limit; and in connection with limiting the speed of the cooling fan, control an operational parameter of the memory to reduce cooling demands generated by the memory.

Abstract: A method for managing the power consumption of an information handling system including a processor and an associated cooling system. The method may include providing power to the cooling system based on a performance/power balance setting, accepting a user input to adjust the performance/power balance setting, and adjusting the power provided to the cooling system based on the adjusted performance/power balance setting. The performance/power balance setting may define a balance between performance of the processor and power consumption of the associated cooling system.

The information handling system can include a power trace operable to produce a temperature differential in response to a current change within the reduced trace width region. A thermistor may be provided in close proximity to the reduced trace width region and can be operable to detect the temperature differential provided in response to the current change.

Abstract: A heat sink is disclosed that includes a set of horizontal fins that are coupled to multiple solid vertical panels. A fan is located near the heat sink to direct air across the surface of the horizontal fins. Vertical panels may be located on the opposite ends of the heat sink to prevent air from exiting from the heat sink in a direction that is perpendicular to the axis of the fan. The presence of the vertical panels within the interior of the heat sink is advantageous because the vertical panels direct the forced air from the fan so that the air flows through the fan in the direction of the axis of the fan.

Abstract: An escape sequence coded in power commands from a system controller, such as a BMC, to a cooling fan controller directs the cooling fan to send identification information coded in tachometer readings to the system controller for use by an information handling system. Electronic confirmation of the cooling fan identification ensures compatibility of the information handling system and cooling fan at initial manufacture or subsequent repair. Communication of information over existing power and tachometer wires supports the electronic confirmation without adding additional communication lines. Further, once a communication link is established between an information handling system controller and a cooling fan, other functions are enabled, such as a reflash of the cooling fan controller firmware.

A feedback communications link may be provided between the thermoelectric cooler and the heat source to regulate the operation of the thermoelectric cooler so that the temperature in the vicinity of the heat source is regulated within a temperature range.

Abstract: When a power supply of a redundant power supply array fails or is removed from the computer system, the operating speed of the processor is modulated or throttled, thereby reducing the rate of power consumption by the processor. Each power supply in the array is rated to a power delivery capacity that is less than the maximum power draw of the computer system.

Abstract: An active heat sink is disclosed that includes a fan elements between two sets of fins. When activated the fan forces air through the fins in a transverse direction across the length of the fins. Because the blades of the fan are bracketed on both sides by the fins of the heat sink, a fan guard is not necessary or installed over the blades of the fan.
