For cooling of information technology devices, micro fan is installed at narrow and small space in the device. Restricted installation consists of not only high system impedance but also inlet or outlet obstacle that is extremely close to fan inlet or outlet. As a result, performance gets much lower and performance characteristics so called P-Q curve which is provided by fan manufacturer can’t applied to actual cooling design. So it is required to make database of effect of such obstacles on performance. The present study is an attempt to clarify the effect of inlet obstacle to micro axial fan on the performance by experiment and flow simulation. The obstacle was round plate which diameter and clearance to the fan inlet were varied and tested. Key Words : Micro axial fan, Inlet obstacle, P-Q curve, Performance measurement, CFD
