PROCESSOR SKIN TEMPERATURE POWER MANAGEMENT BASED ON MULTIPLE EXTERNAL SENSORS

Abstract:

A processing unit manages temperature by correlating readings from a plurality of external temperature sensors to a skin temperature of the processing unit, wherein the correlation is based on characteristics of a computer chassis that is to include the processing unit. The processing unit is mounted on a printed circuit board (PCB) or other substrate that is to be placed in a computer chassis. Each of a plurality of temperature sensors is placed at a different location of the PCB to provide temperature readings from a variety of locations of the PCB. A temperature controller of the processing unit receives temperature readings from the plurality of sensors and correlates the temperature readings with a skin temperature of the processing unit based on a plurality of correlation values.
