The above chart compares the P/Q curves of the three fan models and maps them on sample impedance curves of a typical PC case, heatsink and radiator in order to demonstrate how much air the fans can push through when working against the airflow resistance that these applications represent. As can be seen from the chart, the NF-F12 produces higher maximum static pressure (top left) and the NF-S12A produces higher maximum airflow (bottom right), but at the relevant operating points, namely the impedance curves of the three sample applications, the NF-A12x25 provides a better balance of static pressure and airflow than the other two fans. This is the cornerstone of the NF-A12x25’s superior real-world performance.
