Abstract
A predefined mathematical relationship that is stored in the memory of a computing system is accessed, wherein the relationship refers to temperatures of a number of points in the system, wherein the points together define a zone. The mathematical relationship yields a representative temperature for the zone. Temperature data from sensors in the system is obtained and applied to thermal models, to estimate the temperatures of at least some of the points that define the zone. The representative temperature for the zone is computed using the estimated temperatures as input to the mathematical relationship. A decision is then made on whether or not to change a power consuming activity limit in the system, based on the computed representative temperature. Other embodiments are also described and claimed.
