Abstract

Systems and methods of adaptive thermal control are provided for information handling system platforms that may be implemented to automate and scale fan control settings by making the fan control settings relative to a reported component thermal control parameter value from a component of an information handling system platform, such as a CPU or other heat generating component. In one example, bounds for system use of vendor or component manufacturer-reported thermal control parameter values may be set for system cooling so as to confine use of these values within information handling system platform limits characterized by a manufacturer of an information handling system platform.
