Abstract: A management controller is configured to determine a thermal resistance of a heat sink, and determine a thermal resistance curve that includes the thermal resistance. The management controller may also determine a fan speed setting corresponding with the thermal resistance, and set a speed of the fan based on the fan speed setting.

Abstract: A closed-loop control system may include an integrator configured to, based on an error between a setpoint temperature and a measured temperature, determine an integrated error indicative of a time-based integral of the error, a proportional-integral controller configured to, based on the integrated error and the error, generate a proportional-integral output driving signal, and control logic configured to control power consumption of a component based on the proportional-integral output driving signal.

Abstract: Systems and methods of controlling the fan speed of one or more secondary variable speed cooling fans of an information handling system in real time by dynamically and adaptively shadowing the fan speed of another primary variable speed cooling fan or by so shadowing the fan speed of the variable cooling fan/s of a primary cooling fan zone including other variable speed primary cooling fans of the same information handling system.

Abstract: An information handling system includes a first fan in a first location for cooling a first component of the information handling system, a second fan in a second location for cooling a second component of the information handling system, and a management controller. The management controller determines that the first fan has experienced greater stress than the second fan, and recommends that the first fan be placed in the second location and that the second fan be placed in the first location.

Abstract: A system may include a plurality of temperature sensors configured to sense temperatures at a plurality of locations associated with an information handling system, a cooling subsystem comprising at least one cooling fan configured to generate a cooling airflow in the information handling system, and a thermal manager communicatively coupled to the plurality of temperature sensors and the cooling subsystem. The thermal manager may be configured to, based on at least a power provided to a subsystem of the information handling system, estimate a thermal condition proximate to the subsystem and set a speed of the at least one cooling fan based on the estimated thermal condition and a required cubic airflow rate associated with the subsystem, wherein the required cubic airflow rate is determined based on a required linear airflow velocity associated with the subsystem and a net cross-sectional area through which the cooling airflow travels.
