Noctua NF-S12A PWM chromax.black.swap fan - 120mm [NF-S12A PWM CH.BK.S]

Noctua is one of the well-known sizes in the silent cooling sector. The Austrian manufacturer's CPU coolers in particular enjoy an excellent reputation. They combine excellent processing quality with high cooling performance and minimal noise development. The fans developed by Noctua, which are also available separately, are also largely responsible for this, in order to serve as CPU fans or, as here, as case fans.

The NF-S12A case fan marks the third generation of Noctua's classic S12 series, which has received more than 250 awards and recommendations in the international trade press. Now, in response to multiple customer requests, Noctua has released this popular fan in all black - under the name extension Chromax Black Swap.

Fortunately, Noctua has not changed anything in terms of technology. Furthermore, the finely tuned blade geometry with anti-stall knobs and the new AAO frame (short for Advanced Acoustic Optimization) of the NF-S12A PWM Chromax.Black.Swap ensures up to 8% higher efficiency compared to its renowned predecessor the conveying capacity as well as the noise development. Its excellent running smoothness, the SSO2 reference class bearing and Noctua's proven premium quality make the NF-S12A PWM Chromax.Black.Swap a fine choice for noise-optimized case cooling.

The NF-S12A PWM Chromax.Black.Swap uses the third evolutionary stage of Noctua's classic straight blade design, which has earned the S12 series countless recommendations from hardware enthusiasts and journalists around the world. Further optimized for even better airflow/noise efficiency, it makes the NF-S12A PWM Chromax.Black.Swap the ideal quiet case fan.

The anti-stall knobs of the NF-S12A PWM Chromax.Black.Swap reduce vortex shedding phenomena in situations with medium to high drag and thus extend the so-called stall margin. This makes the NF-S12A PWM Chromax.Black.Swap even more versatile than its predecessor and enables better results on heatsinks and radiators.

Noctua's AAO (Advandced Acoustic Optimization) frames have integrated vibration buffers as well as a stepped inlet area (Stepped Inlet Design) and an inner microstructure (Inner Surface Microstructures), which enable even better performance/noise efficiency.

The graduated inlet area of the stepped inlet design creates more turbulence in the inlet. This facilitates the transition from laminar to turbulent flow, which adheres better to the frame (flow attachment) and thus increases the suction capacity of the fan, especially where the suction area is limited.

The microstructure on the inside of the frame (Inner Surface Microstructures) creates a boundary layer through which the tips of the fan blades move. This reduces the flow separation from the suction side of the blade tips, resulting in a significant reduction in torsional noise and an increase in pressure and airflow efficiency.

The NF-S12A PWM Chromax.Black.Swap is equipped with the further optimized second generation of Noctua's proven SSO bearing system. With SSO2, the rear magnet sits closer to the fan axis for even better stabilization, resulting in further improved precision and durability. With the NF-S12A PWM Chromax.Black.Swap, the decoupler corners can also be used in multiple colors. They come with the fan in the colors black, white, yellow, green, red and blue.

Noctua's fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-S12A PWM Chromax.Black.Swap has an MTBF specification of over 150,000 hours and comes with a full 6-year manufacturer's warranty.
