In this paper, the effect of the configuration of intake/exhaust fans on the cooling performance of CPU was investigated both numerically and experimentally. In the experiment, the temperatures of CPU and exhaust air were measured for various fan-configurations in order to find an optimal fan-configuration when the wall of PC case was in an adiabatic condition and CPU was cooled down by a fan with heat-sink. In the numerical simulations, steady conjugate heat transfer problems, where CPU with heat source is cooled down by both conduction and convection, were solved using a commercial code. The results of simulations qualitatively agreed with those of experiment in terms of cooling performance of CPU and the temperature and velocity fields obtained from simulations with four configurations were discussed.
