| ABSTRACT:-In this paper an investigation of five lengths of three different materials (steel, copper and aluminum) of one quadrate type of heat sink (which commonly used in earlier high performance graphic cards of built-in motherboards) to measure its conductivity and ability of emitting heat when the chipset works at its maximum performance (reaches a temperature of nearly 60o C) and to investigate the relationship between the heat sink length ,material and its performance taking cost into consideration. It's known that for emitting heat copper came 1st then aluminum and steel in 3rd place, which conform the results, but if we take cost into consideration the aluminum model takes the lead, the results also shows the effect of fins length upon heat sink ability of dissipation heat and it conclude that an aluminum heat sink of 2 -2.5 cm fins length is the best.
