Noctua NF-A20 PWM chromax.black.swap, Case fan, 200 mm, black

Description

Having received dozens of awards and recommendations from international hardware websites and magazines, the NF-A20 has established itself as a default choice when it comes to premium-quality fans. The chromax.black.swap edition combines the NF-A20’s signature quiet cooling performance with an attractive design. The NF-A20 PWM chromax.black.swap is the perfect choice for all users who value individual, focused build aesthetics just as much as superior quality and performance.

• Flow acceleration channels
• AAO frame
• Stepped inlet design
• SSO2 bearing
• Metal bearing shell
• Custom-designed PWM IC with SCD

• Flow acceleration channels
  The NF-A20 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 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.
• SSO2 bearing
  The NF-A20 features the further optimized second generation of Noctua’s renowned, 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 a 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
  By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.
