Product Description
The NF-S12A is one of Noctua's renowned and popular fans. Its outstanding airflow efficiency and superb acoustics make it ideal for case cooling and other low-impedance applications. The chromax.black.swap edition combines the NF-S12A's signature quiet cooling performance with an attractive design and a bundle of swappable anti-vibration pads, that allow the color-customization of the fan to match individual build color schemes. Topped off with Noctua's trusted premium-grade SSO2 bearing and long hours MTTF, the NF-S12A PWM chromax.black.swap is the perfect choice for all users, who value individual, focused build aesthetics just as much as high quality and performance.
Product Summary
The NF-S12A PWM chromax.black.swap comes with anti-vibration pads. By combining the various colors or leaving off the pads on one side, the fan can be coordinated with most popular build color schemes out of the box.
The NF-S12A's Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan's stall margin. This means, that the NF-S12A is even more versatile and can achieve better performance on heatsinks and radiators.
Noctua's AAO (Advanced Acoustic Optimization) frames feature integrated anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan's performance/noise efficiency.
Noctua's Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.
With the tips of the fan blades plowing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
The chromax line fans feature the further optimized Noctua's time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilization, precision and durability.
In order to guarantee the high degree of manufacturing precision, minimum tolerance and excellent long-term stability, the chromax edition fans sport a CNC milled bearing shell made entirely from brass.
Supporting fully automatic PWM speed control, the chromax edition fans use Noctua's custom-designed NE-FD1 PWM IC, that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
