Certainly, I recommend Quiet PC.

I am very happy with Quiet PC. My package arrived in Spain in only a few days, and everything was just fine. They offer good... (14th November 2017 via Trustpilot)

Noctua NF-A20 PWM 200mm x 30mm PWM 4-pin Fan

Noctua have crammed all of their expertise in to this exceptionally quiet new 200mm PWM fan.

The NF-A20 is a highly optimised, premium quality quiet 200mm fan. Featuring an AAO (Advanced Acoustic Optimisation) standard frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A20 brings the renowned quiet cooling performance of Noctua's award-winning A-series to the increasingly popular 200mm form factor. The PWM version uses Noctua's custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers, which allows it to strike a perfect balance between quietness and ventilation performance in each given situation. Its superb running smoothness, reference-class SSO2 bearing and Noctua's trusted premium quality make the NF-A20 an elite choice for the highest demands.

Award-winning Noctua quality in 200mm size

While more and more PC cases support 200mm intake, side-panel or exhaust fans, many of the bundled stock units and available aftermarket options are of questionable quality. By contrast, the NF-A20 is a true premium grade solution worthy of Noctua's award-winning A-series.

154mm, 110x180mm and 170mm hole spacing

In order to ensure broad compatibility with today's PC cases, the NF-A20 features three sets of mounting holes: While the 154x154mm and 110x180mm spacing allow it to replace most 200mm fans, the 170x170mm spacing is used by many 230 and 250mm fans, which can thus also be replaced by the NF-A20.*

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 (Advanced Acoustic Optimisation) 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 ploughing 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.

Integrated anti-vibration pads

Integrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems.

Custom-designed PWM IC with SCD

Supporting fully automatic PWM speed control, the fan uses 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.

Low-Noise Adaptor

The NF-A20 PWM is supplied with a L.N.A. that reduces the maximum fan speed from 800 to 550rpm. The L.N.A. can be used either to run the fan at a fixed speed of 550rpm or to cap the maximum speed when using automatic PWM control.

Extensive cabling options

The fan's short 200mm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary. Both cables are fully sleeved and a 4-pin y-cable allows the connection of a second fan to the same PWM fan header for automatic control.

SSO2 bearing

The NF-A20 features the further optimised 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 stabilisation, precision and durability.

6-year manufacturer's warranty

Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A20 features an MTTF of more than 150,000 hours rating and comes with a full 6-year manufacturer's warranty.

  • *As there is no fixed industry standard for the size or hole spacing of 200mm, 220mm, 230mm or 250mm fans, please carefully check both the hole setup of your chassis and the available space (the NF-A20 is 30mm thick whereas some other 200mm fans are only 20mm!) in order to verify that the NF-A20 is compatible with your chassis. In case of doubt, please contact your chassis manufacturer.
