Abstract

This paper investigates desktop computer system power optimization with Modelica. Firstly, microprocessor power equation is modeled with voltage and temperature dependency. Secondly, steady state heat transfer path is modeled as a variable thermal resistance with fan power change and is combined with microprocessor power model to discuss optimum working point of fan which minimizes power consumption of the system. After that, transient heat transfer path modeling is explored as Cauer thermal network creation.
