Abstract
Parametric study is conducted for optimizing the fan arrangement of the electronic equipment with several fans inthe equipment. Those fans are cooling for central processing unit (CPU), for power supply unit (PSU), and for the other devices in the equipment (system exhaust fan). We have used the Taguchi method of the experimental design for finding the optimal arrangement of those fans. The result shows system fans with high wind capacity does not always mean to enhance the cooling performance of the electronic equipment. When there is a system exhaust fan, it is recommended to set flow direction of CPU fan to up-flow, it is just opposite to flow direction of commercial CPU fan. This setting enables to exhaust the hot wasted air from CPU very efficiently. It is also found that the separation of the CPU from the PSU cooling system is an effective way to cool both components respectively.
