NF-S12 / NF-P12

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 following illustration shows how this approach differs from common all-round solutions:

While the NF-S12B delivers less static pressure, it provides a better airflow/noise ratio. Therefore, it's perfectly suited for case ventilation as well as all applications which don't demand high static pressure and where maximum quietness is the first priority. The NF-P12 on the other hand provides a better pressure/noise ratio and should therefore be the first choice for all applications which demand high static pressure such as CPU cooling.

Noctua
22.10.2014 - El Chapuzas Informático NF-A4x10 5V
Test verdict: "Los ventiladores Noctua NF-A4/A8/A9 demuestran una vez más el buen hacer de Noctua, pues ofrecen un gran rendimiento con una sonoridad mínima. Además, llegan acompañados de un excelente kit de accesorios, algo de lo que pocas marcas pueden presumir." (Iván Martínez, El Chapuzas Informático)

Test verdict: "The NH-D15 is a great option for those chasing a super quiet rig and builders who don't want to use closed loop water coolers but still want to chase heavy overclocks. It isn't cheap but it's build to last and performs well at a whisper. This is a well finished and thought out cooler and a worthy successor to the iconic NH-D14." (Phil Carroll, PCGamers.net.au)

Test verdict: "Noctuas nye topmodel lever uden problemer op til forventningerne. Et lækkert kvalitetsprodukt som leverer hele vejen igennem, især når det kommer til køleevne. Det er desuden rigtigt flot at se hvor meget Noctua har forbedret sig i forhold til den gamle topmodel, NH-D14, som stadig er en god køler, bare ikke helt så god som den nye NH-D15."
