Operating Point - Thermal Design
The two figures below show the nonlinear relationship between airflow and static pressure for a typical fan. The performance of a fan in a specific application is determined by the intersection of the System Impedance Curve and the Fan Characteristic Curve. The System Impedance Curve is a property inherent to an individual electronics enclosure. This curve can easily be generated experimentally, by testing the enclosure pressure at various airflow rates.
