Abstract- The appropriate operating temperature of the processor depend upon its manufacturer and processor speed where the sensor is to be found and what programs is currently running. In the present work the studies were performed in order to optimize geometrical fin parameters for natural convective heat transfer from continuous and discontinuous heat sink installed at North and south bridge and at CPU main processor in computer system and discontinuous heat sink proposed for geometrical and cost effective material optimization. In the present work it has been observed that the interrupted fins exhibit a thermal boundary layer interruption which helps increase the heat transfer rate. The study aspires to deal with shortcoming by investigating the effect of fin interruption on the efficiency with which the heat is transferred from the heat sink to the environment. In addition fin interruption leads to noteworthy weight reduction which can lower the manufacturing costs. In contrast adding up interruptions that reduce the heat transfer rate which decrease the total heat transfer rate from the surface area. These two opposing effects clearly indicate that an optimum fin interruption provide the maximum heat transfer rate from naturally cooled heat sink.
