N2 - This study presents the optimization of the geometry of pin-fin heat sink with un-uniform fin dimensions. A procedure is presented to find the optimum geometry of pin-fin with un-uniform fin heights and widths. It is concluded that the highest temperature is lower and the temperature gradient is smaller in the optimum geometry, and the fin heights and widths near the central part of the heat sink are higher and wider than the fins at the edge. As the total volume of fins increases, the entropy generation decreases while the decreasing rate slows down.
