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
26.05.2015 - Tweak.dk NF-A9 PWM
Test verdict: "Endnu en gang har Noctua leveret varen. De har modificeret og moderniseret en allerede god blæser til at blive om muligt endnu bedre. Denne blæser er blevet forbedret på flere områder, både når det gælder ydelse kontra støjforholdet, nyt og forbedret kugleleje og tilbehør. Alt i alt en rigtig god blæser, som flytter en masse luft uden at larme som en flyvemaskine." (Kim Monberg, Tweak.dk)

26.05.2015 - kingdomgame.it NH-L9x65
Test verdict: "Noctua ha ancora una volta dimostrato la sua capacità nel creare un prodotto di altissima qualità, questa volta però in spazi contenutissimi. L'NH-L9x65 è incredibilmente piccolo e versatile nelle più svariate configurazioni e capace di dissipare per bene anche i processori più esigenti. Se state pensando ad una build che occupi davvero poco spazio e trovare un dissipatore ideale è stato un problema, l'NH-L9x65 potrebbe essere la vostra soluzione definitiva."
