What is static pressure important for?
Static pressure is important for cooling performance in situations where completely free air circulation is not possible. This can be a narrow-meshed housing inlet, or radiators and heat sinks with their closely spaced cooling fins. To guarantee a high air circulation through these resistors, the highest possible static pressure is required.https://www.arctic.ac/en/What-is-static-pressure-important-for
Without a correspondingly high static pressure, the desired air circulation can not be achieved, which means that cooling capacity is lost.
