Thermal Control Systems And Methods For Information Handling Systems

摘要

Systems and methods are provided for information handling system thermal control that employ configuration-based temperature feedback, e.g., by using configuration-based fan speed control based on real time individual measured component temperatures. In one example, the disclosed systems and methods may be implemented to allow inputs from one or more hardware temperature sensors to set cooling fan speeds and/or power capping levels in a closed loop fashion, rather than relying solely (or at all) on system inlet ambient temperature.

主权项

1. An information handling system, comprising:
an enclosure; one or more heat generating hardware components contained within the enclosure; and thermal management circuitry comprising at least one processing device coupled to non-volatile memory, the non-volatile memory including thermal configuration information stored thereon, and the processing device being configured to access the stored thermal configuration information and to perform thermal control by controlling at least one of cooling or power capping for the one or more heat generating hardware components based on the accessed stored thermal configuration information in combination with feedback of the sensed temperature of at least one of the hardware components; where the thermal configuration information comprises a defined functional relationship between at least one of cooling fan speed level or power capping level and the sensed temperature of the at least one hardware component in the feedback to the processing device; and where the processing device is configured to compare a system inventory of hardware circuitry components of the information handling system that are coupled to the processing device against configuration entries in a configuration table of the thermal configuration information to determine matched configurations for use in the thermal control.
