    摘要: In accordance with embodiments of the present disclosure, an information handling system may include a processor and an air mover control system for controlling at least one air mover configured to drive airflow to one or more components of the information handling system. The air mover control system may be configured to read from an information handling resource of the information handling system, wherein the information handling resource comprises an active cooling system, a fault condition cooling requirement defining a minimum airflow required by the information handling resource from the at least one air mover in presence of a fault condition of the active cooling system. The air mover control system may also be configured to read from the information handling resource a variable indicating whether the fault condition of the active cooling system exists. The air mover control system may also be configured to, responsive to the variable indicating the fault condition exists, determine a speed for the at least one air mover to satisfy the fault condition cooling requirement and cause the at least one air mover to operate at the speed.

    摘要: Thermal conditions at processing components disposed in an information handling system are estimated by applying conservation of energy and component power consumption so that discrete control of information handling system exhaust temperatures is more accurately maintained. For example, a PCI backplane communications card has its power consumption estimated based upon its width so that air flow through the information handling system is adequate to meet an exhaust temperature constraint.

    摘要: A baseboard management control subsystem may determine a fan speed value associated with a fan speed used to cool a particular hardware configuration of an information handling system. The baseboard management control subsystem may further determine a power value associated with a power consumed by a fan running at the determined fan speed value. The baseboard management system may manage power within the information handling system based on the determined fan speed value and the determined power value.

    摘要: An Information Handling System (IHS) and method provide for a thermal controller receiving from a temperature sensor a current operating temperature of the at least one functional device. The thermal controller determines a first rate of an air mover based at least in part on the current operating temperature sensed by the temperature sensor and the instantaneous component maximum temperature. The first rate prevents the at least one functional component from exceeding the instantaneous component maximum temperature. The thermal controller determines a second rate of the air mover based at least in part on lifetime average temperature and the long-term average temperature target that is selected for the reliability level. The thermal controller controls the air mover to operate at a higher one of the first and second rates.

    摘要: 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.
