In the present work the experimental, numerical and analytical studies have been carry out with the purpose of optimization of geometrical fin parameters for heat sink of North Bridge used in personal computer system based on natural convective heat transfer. It has been observed that the perforated heat sink indicates the thermal boundary layer interruption which helps to increase the heat transfer rate. The main objective of this work to deal with deficiency by investigating the effect of heat transfer rate in actual as well as interrupted heat sink. it have been also observed that the interrupted heat sink has less bulky means contained less material which may also lower its manufacturing cost. by using the interrupted design of heat sink it is also revealed that the total heat transfer rate increases from the surface area. results indicates, the proposed design in present work of Northbridge heat sink is giving better performance compared to the actual heat sink.

Keywords- Keywords: Northbridge heat sink, natural convection, heat transfer rate, thermal Analysis etc.
