Noctua NF-A9 FLX korpuso ventiliatorius – 92mm

Noctua is a renowned name in the silent cooling industry, with the Austrian manufacturer’s CPU coolers enjoying an excellent reputation. They combine outstanding build quality with high cooling performance and minimal noise levels. This is largely thanks to Noctua’s proprietary fans, which are also sold separately for use as case or CPU fans.

The NF-A9 is a quiet 92 mm premium fan with a square AAO (Advanced Acoustic Optimisation) frame. Its square shape and 92 mm mounting holes make it an excellent choice for use as a case fan in smaller towers, HTPCs, or other enclosures. With advanced aerodynamic design features such as Flow Acceleration Channels, the NF-A9 achieves improved silent cooling performance compared to the highly acclaimed NF-B9.

The FLX version offers three speed settings (1,600/1,250/1,050 RPM) via the included Low-Noise Adapters, providing full flexibility between maximum airflow and nearly silent operation. Its superb smoothness, reference-class SSO2 bearing, and Noctua’s proven premium quality make the NF-A9 FLX a top-tier solution for the most demanding requirements.

Noctua’s NF-B9 has become a standard solution for PC enthusiasts needing premium-quality 92 mm fans. With extensive aerodynamic optimisations, the NF-A9 achieves higher static pressure and an improved airflow-to-noise ratio compared to its renowned predecessor.

The NF-A9’s impeller features Flow Acceleration Channels on the suction side. By accelerating airflow in critical outer regions of the fan blades, suction-side vortex shedding is reduced, resulting in greater efficiency and lower turbulence-induced noise emissions.

Noctua’s AAO (Advanced Acoustic Optimisation) frame includes integrated vibration pads, a stepped inlet design, and inner surface microstructures, which enhance performance-to-noise efficiency.

Anti-vibration pads made of extra-soft silicone reduce the transmission of even the smallest vibrations and are compatible with all standard screws, common mounting systems, and fan clips used with CPU coolers.

Despite its improved performance, the NF-A9 FLX has a power consumption of just 0.84 W. This makes the NF-A9 FLX not only environmentally friendly but also helps reduce energy costs!

Noctua fans are renowned for their flawless quality and exceptional durability. Like all Noctua fans, the NF-A9 has an MTBF (Mean Time Between Failures) rating of over 150,000 hours and comes with a full 6-year manufacturer’s warranty.
