Noctua Case Fans : 140mm Noctua NF-P14 FLX Round Quiet Case Fan

Noctua NF-P14 FLX

Following in the footsteps of the successful NF-P12, the Noctua NF-P14 is a highly optimised, premium quality 140mm fan with Vortex-Control Notches for superb quietness and outstanding aerodynamic efficiency. Metal reinforcements, SCD2 technology and Noctua’s premium grade SSO-Bearing guarantee exceptional running smoothness and excellent long-term stability. Using the same hole-spacing as common 120mm fans and achieving a superior airflow/noise ratio, the NF-P14 is ideal for upgrading 120mm CPU or case fans.
 

Using a round frame with the same hole-spacing as common 120mm fans and producing more airflow due to its larger diameter, the NF-P14 is a perfect upgrade for 120mm CPU or case fans. Thanks to the supplied adaptors, the NF-P14 also fits common 140mm mounting holes.

Blade Design With Vortex-Control Notches

Many 140x140x25mm axial fans tend to suffer from low static pressure, making them less suitable for use on CPU coolers or watercooling radiators with tight fin spacing. The NF-P14 on the other hand features a highly optimised nine blade impeller design that’s following in the footsteps of Noctua’s successful NF-P12 and has been carefully fine-tuned for both airflow/noise efficiency and outstanding static pressure. As a result, the NF-P14 lends itself not only to use as a case fan but also to high-impedance applications like CPU cooling.

Thanks to the use of Vortex-Control Notches, an advanced design measure first introduced with the NF-P12 fan, the NF-P14 is surprisingly quiet despite of its impressive airflow and pressure performance. The two Vortex-Control Notches at the trailing edge of each blade make the flows along the suction and pressure side mix more smoothly, allowing for less turbulence and velocity loss, which leads to increased efficiency as well as a significant reduction in noise emission.

Staggering of Vortex-Control Notches

Vortex-Control Notches not only allow the flows to join less abruptly at the trailing edge, but also serve the purpose of psychoacoustic optimisation by making the fan’s acoustic profile more pleasant to the human ear: Due to the Vortex-Control Notches, trailing edge vortices are split up into several smaller vortices, each having slightly different tonal characteristics. The fan’s airflow noise is thereby spread over a wider range of frequencies and, as a result, perceived as much less annoying.
 

	140mm Impeller with Vortex Control Notches Thanks to its psycho-acoustically optimised nine blade impeller with staggered Vortex-Control Notches, the NF-P14 combines superb quietness with exceptional airflow and static pressure.
	Metal Reinforcements Both the impeller hub and the bearing shell of the NF-P14 are metal reinforced in order to achieve ultimate manufacturing precision, high durability and vibration-free running.
	Round frame with 120mm mounting holes Using a round frame with the same hole-spacing as common 120mm fans and producing more airflow due to its larger diameter, the NF-P14 is a perfect upgrade for 120mm CPU or case fans. Thanks to the supplied adaptors, the NF-P14 also fits common 140mm mounting holes.
	3 speed settings for full flexibility Providing 1200, 900 and 750 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-P14 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.
	Smooth Commutation Drive 2 The latest version of Noctua’s advanced SCD drive system ensures superb running smoothness by eliminating torque variations and switching noises.
	SSO-Bearing Noctua’s time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability.
