Which 120mm fan?

Noctua’s 120mm fans are premium quality solutions that have been thoroughly optimised to achieve the best possible results in specific fields of application. Each of the three models works fine in all typical environments, so you can’t go wrong with either of them, but choosing the model that is best suited for your application can help you to obtain even better results:

NF-S12A NF-P12 NF-F12
Case Ventilation
Heatsink & Radiator Performance

NF-S12A: The NF-S12A has been optimised for “low impedance” applications that don’t require high static pressure and thus combines moderate pressure with outstanding airflow and superb quietness of operation. Choose the NF-S12A for case ventilation, applications with little or no obstruction to airflow as well as all other applications where minimum noise emission has first priority.

NF-P12: The NF-P12 has been designed with more pressure demanding “high impedance” applications in mind. It provides an even balance of high static pressure, high airflow and excellent quietness, which has made it a standard choice for low noise CPU cooling, cases with tight fan grills and other low noise cooling applications with mid- to high airflow resistance.

NF-F12: The NF-F12’s unique Focused Flow™ system produces extremely high static pressure and focuses the airflow in order to achieve even better results on air cooling heatsinks and water cooling radiators. With a top speed of 1500rpm, it also offers more performance headroom for less noise-sensitive applications. Choose the NF-F12 if you’re looking for the best possible performance on heatsinks and radiators.

Noctua 120mm Fans Comparison

13.10.2015 - NH-D15S
Test verdict: "Just like the change from the NH-D14 to the NH-D15 seemed minor physically, closer inspection and testing revealed bigger changes than what can be observed by merely unboxing. It feels like Deja Vu with the NH-D15S but the improvements are surprisingly even more profound." (Ron Perillo,

12.10.2015 - NH-D15S
Test verdict: "En conclusión, ¿Compraríamos o recomendaríamos el Noctua NH-D15S? Definitivamente. Noctua es el Rolls Royce de las soluciones de refrigeración y no dudamos un solo instante en recomendar este producto a ojos cerrados." (Sebastian Rodriguez Ayala,

12.10.2015 - NH-L9x65
Test verdict: "Noctua has always been at the forefront of cooling prowess and engineering new methods to enhance the size to performance ratio. While the NH-L9x65 is larger and less versatile, there’s no denying the impeccable advancements in heat dissipation. The performance numbers are stunning and it’s crystal clear that the NH-L9x65 is a pioneering product and the best cooler I’ve encountered for use in exceptionally small cases." (John Williamson,

12.10.2015 - NH-U9S
Test verdict: "No geral, a Noctua presenteia-nos com mais dois coolers de qualidade, como já é habitual da marca." (Pedro Fernandes,
