NF-A12x25: Performance comparison to NF-F12 and NF-S12A

Unlike the award-winning NF-F12 and NF-S12A models, which are specialised solutions for specific applications, the NF-A12x25 has been conceived to be a true all-rounder with superior performance in most common configurations: Whereas the NF-F12 is optimised for maximum static pressure and the NF-S12A is optimised for maximum airflow, the pressure to airflow (P/Q) curve of the NF-A12x25 has been carefully fine-tuned in the mid-section that is critical for achieving the best results in all common applications.

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.
