This research is to investigate the performance analysis of cooling fan of the IT and electronic device with two different blade types and three different blade numbers of the cooling fan. Velocity, and temperature distributions of fluid over the flow domain of the flow channel are numerically calculated for the optimum design of flow channel with uniform inlet velocity. According to the calculations of convective heat transfer coefficient between blade and atmosphere in the flow domain, case 2 with 6 blases type shows highest performance of the cooling fan shapes in the present cooling fan model considering manufacturing process and cost.
