Noctua chromax NF-A14 PWM, Case fan, 140 mm, black

Description

The NF-A14 is one of Noctua’s renowned and popular fans. Its square frame makes it ideal for use on water cooling radiators or as a case fan. The chromax.black.swap edition combines the NF-A14’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-A14 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.

• Swappable anti-vibration pads
  The NF-A14 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.
• Square frame
  The NF-A14’s square frame with mounting holes makes it a premium grade replacement for common ase fans and perfect for use on the water cooling radiators, where its square shape will ensure full coverage and optimal pressure performance.
• Flow Acceleration Channels
  The NF-A14 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise.
• AAO frame
  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.
• Stepped Inlet Design
  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.
• Inner Surface Microstructures
  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.
• SSO2 bearing
  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.
• Metal bearing shell
  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.
• Custom-designed PWM IC with SCD
  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.
