This paper describes the relationship between fan performance and configuration factors such as flow inlet porosity of an electronic enclosure, or flow obstacles which imitate high-density packages and restricted flow area configurations for a development of a fan performance prediction model. We focus on an electronic enclosure or an obstacle in front of the fan individually as factors which have dominant effects to the fan. First, we installed an enclosure model in front of the test fan and measured its P-Q curves while operating it in an enclosure. Secondly, we installed a perforated plate in front of the fan as an obstacle and investigated the P-Q curve changes as affected by the position and distance between the adjacent area and the fan. When the perforated plate was located in front of the fan, the P-Q curves were adversely affected, and the flow rate was determined by the open area ratio in front of the fan.
