Noctua NF-S12A PWM Chromax.Black.Swap PC fan (W x H x D) 120 x 120 x 25 mm

The NF-S12A has received more than 100 awards and recommendations from international hardware websites and magazines and is one of Noctua's most renowned and popular 120mm fan models. Thanks to its excellent volume flow efficiency and excellent acoustics, it is ideally suited for use as a housing fan and other applications with low back pressure. The Chromax.black.swap edition combines the unique silent cooling performance of the NF-S12A with an attractive, completely black design and exchangeable anti-vibration pads in red, white, blue, green, yellow and black – in this way the fan can be individually color-coded and adapted to specific color schemes. Additional accessories, such as colored cables, additional anti-vibration pads or anti-vibration mounts, can be used for even more complete customization. With Noctua's proven SSO2 premium warehouse and more than 150,000 hours MTTF, the NF-S12A PWM chromax.black.swap is the perfect choice for users who place just as much emphasis on individual, focused esthetics as on first-class quality and performance.

Award-winning NF-S12A design
With more than 100 recommendations and awards from the international trade press, the NF-S12A has become a reference in the field of high-quality 120mm fans. Its outstanding efficiency has already convinced tens of thousands of customers around the world.

Chromax.black.swap Edition
Maximum color selection! Noctuas chromax.black.swap fans can be customized with the help of the accompanying, replaceable anti-vibration pads as well as optional anti-vibration attachments and cable: Perfect for enthusiasts who are looking for real premium fans, which can be adapted to different color schemes (e.g. complete black, black/white, black/red or black/blue).

Exchangeable anti-vibration pads in 6 colors
The NF-S12A PWM chromax.black.swap is supplied with 4 black, white, red, blue, green and yellow NA-AVP1 anti-vibration pads. By combining the different colors with black or by leaving the pads on one side of the fan, the fan can be adjusted ex works to most common color schemes. Additional NA-SAVP1 sets can be purchased separately to provide the same color on both sides of the fan.

Anti-stall knobs
Those of the NF-S12A reduce eddy-release phenomena in situations with medium to high flow resistance and thus extend the so-called stall margin (flow-reduction limit). This makes the NF-S12A even more versatile than its predecessor and enables better results on heatsinks and radiators.

AAO frame system
Noctuas AAO (Advanced Acoustic Optimization) frames have integrated vibration buffers, a stepped inlet design and an internal surface microstructure (Inner Surface Microstructures) that enable even better performance/noise efficiency.

Quilted inlet design
The stepped inlet area of the Stepped Inlet Design creates more turbulence in the supply. This facilitates the transition from laminar flow to turbulent flow, which is better attached to the frame (flow attachment) and thus increases the suction capacity of the fan, especially with a limited suction area.

Inner Surface Microstructures
The inner surface microstructure (Inner Surface Microstructures) creates a boundary layer through which the tips of the fan blades move. This reduces the current separation from the suction side of the blade tips, resulting in a significant reduction of the rotating tone and an increase in the pressure and air flow efficiency.

SSO2 bearings
The fans of the chromax line are equipped with the second, further optimized version of Noctua's renowned SSO bearing, which has been proven over many years. With SSO2 the rear magnet sits closer to the fan axis and thus causes an even better stabilization, which leads to a further improved precision and durability.

Bearing shell made of metal
In order to guarantee the greatest possible degree of manufacturing precision, minimum tolerances and excellent long-term stability, the fans of the Chromax line use a CNC machined bearing shell made of brass.

PWM IC WITH SCD
The fan supports fully automatic speed control via PWM and uses Noctua's specially designed NE-FD1 chip for this purpose. This new PWM IC integrates Noctuas Smooth Commutation Drive (SCD) technology, which minimizes PWM switching noise and makes the fan quieter at low speeds.

Stops at 0% PWM
The fan can be brought to a complete standstill by being controlled by the mainboard or a fan control with a PWM duty cycle of 0%. This makes it ideal for semi-passive systems, which switch off the fans under low thermal load and thus run completely silently.
