This paper introduces a brief review about the way of heat extraction enhancement from heat sink using fins of different types and different shapes and also with different shape of perforation. Extended surfaces from the base plate or heat sink is nothing but they are FINS. There are various types of fin exits. They are Rectangular, Square, Annular, Elliptical, Cylindrical or Pin fin which is utilized with different geometrical combinations. To achieve maximum temperature droop from the base surface or heat sink by using fins numerous trials are completed or being carried out for designing optimized Fin. The optimization of Fin can be achieved by increasing surface contact area with the atmospheric air. In these days there are numbers of experiment is done on fins like Solid fin, Porous fins and Solid fins with perforation, has also been brought off. The various design modifications which are implemented and studied analytically and experimentally by the researchers using ANSYS Work bench is been discussed in this review paper.
