Abstract:
An electronic system includes a fan and a fan controller connected to the fan to control a speed of the fan. The fan controller has storage locations for storing thermal data used by the fan controller to control the speed of the fan. A thermal sensor generates a first portion of the thermal data, which is readable by the fan controller, and which the fan controller stores in a first portion of the storage locations. A device generates a second portion of the thermal data, which is not readable by the fan controller. An agent writes the second portion of the thermal data to a second portion of the storage locations.
