NF-S12B & NF-P12: Technical Backgrounds
In the design and development of axial fans, the three aerodynamic key parameters of airflow, pressure and noise play a major role. Usually, the goal is to achieve the amount of airflow and static pressure required by a specific application at the lowest possible noise emission. The design should hence provide the optimal balance of airflow, pressure and noise for a given application.
However, even in the field of PC cooling, each application has different requirements: Whereas CPU coolers with tighter fin-spacing require high static pressure, it's mostly the airflow to noise ratio that counts when it comes to case fans.
Common fans are usually designed to be all-round solutions with compromises in certain areas in order to achieve solid results in all typical applications.
Noctua, on the other hand, is following a two-fold approach with its S12 and P12 fan series in order to achieve optimal results at various applications: While the NF-S12B was optimized so as to provide a class-leading airflow to noise ratio and therefore makes for an excellent case fan, the NF-P12 was designed to produce high airflow and an outstanding amount of static pressure, which makes it perfect for use on CPU coolers and other high-impedance applications.
The NF-S12B is recommended for the following applications:
- Case ventilation (with the exception of very restrictive fan grills, filters or significant obstruction to airflow)
- CPU coolers with wide fin-spacing
- Water-cooling radiators with wide fin-spacing
- All applications where minimum noise emission has first priority
The NF-P12 is recommended for the following applications:
- CPU coolers with tight fin-spacing
- Water-cooling radiators with tight fin-spacing
- Power supplies
- Storage solutions
- Cases with very restrictive fan grills and filters
- All applications with significant obstruction to airflow
