Quick Answer
Neither matters more universally. Specific use dictates priority. Static pressure overcomes impedance across radiators, heatsinks, and dense filters. High airflow moves maximum volume through open, unrestricted case spaces. Higher pressure blades generate more acoustic noise. Check published mmH2O and CFM ratings, then match fan capability to airflow resistance and noise limits.

Static pressure matters more than airflow only when the airflow path is restrictive. Where the path is open, airflow matters more. Fan datasheets quote two numbers, maximum volumetric flow at zero back-pressure and maximum static pressure at zero flow, and a fan never operates at either point in a real enclosure. The operating point is the intersection of the fan’s pressure-flow (P-Q) curve with the system impedance curve of the heatsink, radiator, filter or enclosure it serves. This guide covers how to evaluate that intersection, where each metric dominates, how to read specifications, and how to select fans.
Airflow vs Static Pressure: The Underlying Physics
Airflow (Q) is the volume of air moved per unit time, expressed in CFM (ft³/min), m³/h or L/s. Conversions: 1 CFM = 1.699 m³/h = 0.4719 L/s. Static pressure (ΔP) is the pressure differential the fan can sustain across a restriction, expressed in mmH2O, inH2O or Pa. Conversions: 1 m
