Noctua belongs to the well-known sizes in the silent cooling area. Especially the CPU coolers of the Austrian manufacturer enjoy an excellent reputation. They combine excellent processing quality with high cooling performance and minimal noise. The self-developed fans from Noctua are also responsible for this, which are also available separately in order to serve as a CPU or as a housing fan. The NF-S12A enclosure fan marks the third generation of Noctua’s classic S12 series, which has received more than 250 awards and recommendations in the international press. Now, Noctua has published this popular fan in black – under the name extension Chromax Black Swap – on multiple customer requests. Technically, Noctua has changed nothing. Furthermore, the finely-adjusted blade geometry with anti-stall knobs and the new AAO frame (short for Advanced Acoustic Optimization) of the NF-S12A PWM Chromax.Black.Swap provides an up to 8% higher efficiency in comparison to its renowned predecessor the output as well as the noise development. Its excellent running stability, the SSO2 reference class bearing and Noctua’s proven premium quality make the NF-S12A PWM Chromax.Black.Swap a select choice for noise-optimized cabinet cooling. The NF-S12A PWM Chromax.Black.Swap uses the third evolutionary stage of Noctua’s classic straightblade design, which has received countless recommendations from hardware enthusiasts and journalists around the world for the S12 series. Further optimized for even better airflow / noise efficiency, it makes the NF-S12A PWM Chromax.Black.Swap the ideal silent case fan. The anti-stall knobs of the NF-S12A PWM Chromax.Black.Swap reduce turbulence phenomena in situations with medium to high flow resistance and thus extend the so-called stable margin (flow stop limit). This makes the NF-S12A PWM Chromax.Black.Swap even more versatile than its predecessor and allows better results on heat sinks and radiators. Noctuas AAO (Advaced Acoustic Optimization) frames have built-in vibration buffers, a stepped inlet design, and an inner surface microstructure that allows even better performance / noise efficiency. The stepped inlet area of ??the Stepped Inlet design creates more turbulence in the inflow. This facilitates the transition from laminar to turbulent flow, which is better adhered to the frame (flow attachment) and thus, especially in the case of a limited suction area, increases the suction capacity of the fan. The microstructure inside the inner surface of the frame (Inner Surface Microstructures) creates a boundary layer through which the tips of the fan blades move. This reduces the current dissipation from the suction side of the blade tips, which results in a considerable reduction in the rotary sound as well as an increase in the pressure and air flow efficiency. The NF-S12A PWM Chromax.Black.Swap is equipped with the further optimized second generation Noctua’s proven SSO bearing system. With SSO2, the back magnet is closer to the fan axis, resulting in even better stabilization resulting in further improved precision and durability. The NF-S12A PWM Chromax.Black.Swap can also use the decoupler corners in several colors. The fans are available in black, white, yellow, green, red and blue. Noctuas fans are known for their makellose quality and outstanding longevity. 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 six-year manufacturing warranty.
