Noctua NF-A20 HS-PWM chromax.black
Noctua's NF-A20 has received numerous awards and recommendations from international hardware websites and magazines and is considered the reference for high-quality 200mm fans. The HS-PWM (High-Speed-PWM) version offers an attractive, all-black chromax.black design and an increased Speed of 1200rpm. Compared to the regular PWM version with 800rpm, it achieves over 40% higher flow rate and over 90% more static pressure.
Award-winning NF-A20 design
With dozens of recommendations and awards from the international trade press, the NF-A20 has become a reference in the field of high-quality 200mm fans. Its outstanding efficiency has already convinced tens of thousands of customers all over the world.
154mm, 110x180mm and 170mm hole spacing
In order to ensure the widest possible compatibility with today's PC cases, the NF-A20 has three different hole spacings: While the 154x154mm and 110x180mm dimensions allow the replacement of most common 200mm fans, the 170x170mm dimension is used for many 230 and 250mm fans. which can also be replaced by the NF-A20.*
Flow Acceleration Channels
The impeller of the NF-A20 is equipped with so-called flow acceleration channels on the suction side. By accelerating the air flow in the critical outer regions of the fan blades, vortex shedding on the suction side is reduced, which leads to higher efficiency and lower turbulence-related noise emissions.
AAO frame system
Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated vibration buffers as well as a stepped inlet area (Stepped Inlet Design) and an inner surface microstructure, which enable even better performance/noise efficiency.
Stepped Inlet Design
The stepped inlet area of the Stepped Inlet Design creates more turbulence in the inlet. This facilitates the transition from laminar to turbulent flow, which adheres better to the frame (flow attachment) and thus increases the suction capacity of the fan, especially when the intake area is limited.
Inner Surface Microstructures
The microstructure in the inner area of the frame (Inner Surface Microstructures) creates a boundary layer through which the tips of the fan blades move. This reduces the flow separation from the suction side of the blade tips, resulting in a significant reduction in the rotational noise and an increase in pressure and airflow efficiency. has.
SSO2 storage system
The NF-A20 is equipped with the further optimized second generation of Noctua's proven SSO bearing system. With SSO2, the rear magnet is positioned closer to the fan axis for even better stabilization, resulting in further improved precision and durability.
metal bearing shell
In order to guarantee the greatest possible degree of manufacturing precision, minimal tolerances and excellent long-term stability, the fans in the chromax line use a CNC-milled brass bearing shell.
PWM IC with SCD
The fan supports fully automatic speed control via PWM and uses Noctua's specially designed NE-FD1 chip. This new PWM IC integrates Noctua's Smooth Commutation Drive (SCD) technology, which minimizes PWM switching noise and makes the fan even quieter at low speeds.
6-year manufacturer's warranty
Noctua fans are known for their impeccable quality and outstanding durability. Like all Noctua fans, the NF-A20 has an MTTF specification of over 150,000 hours and comes with a full 6-year manufacturer's warranty.
Technical data:
*As there is no binding industry standard for the size and hole spacing of 200mm, 220mm, 230mm or 250mm fans, please consult Noctua's case compatibility list and carefully check the hole spacing of your case and the available space (the NF-A20 is 30mm deep, whereas some other 200mm fans are only 20mm deep!) to make sure the NF-A20 is compatible with your case. If in doubt, please contact your case manufacturer.
