Overview

Silence is golden


Take your cooling to the next level with the Noctua NF-A12x25 FLX 120mm fan. This model features an AAO frame, Flow Acceleration Channels and a 0.5 mm blade tip gap thanks to Sterrox liquid crystal polymer combined with a high performance metal hub and motor shaft. Versatile, it will be suitable for various uses thanks to its exceptional performance.
The FLX version allows speed adjustment to 1700/1350 rpm with the included low noise adapter (LNA). It also features SSO2 bearings and a 6 year manufacturer's warranty.

Low Noise Adaptor
The NF-A12x25 is supplied with a Low Noise Adaptator (L.N.A.) which lowers the maximum speed from 2000 to 1700 rpm. The L.N.A. is suitable for both fixed speed operation and PWM clamped operation.
Extensive wiring options
The first fan cable is 20cm short, minimising the space required for routine use. The supplied 30cm extension cable will solve any distance problems.
Flow Acceleration Channels
The NF-A12x25 impeller is equipped with flow channels on the suction side of the fan. The flow acceleration generated at the tips of the blades creates a more massive, less dispersed suction, thus increasing efficiency.
AAO frame
Noctua's AAO(Advanced Acoustic Optimisation) frames are equipped with anti-vibration mounts and benefit from exclusive optimisations to push the limits of performance and silence.
Stepped inlet design
Noctua's Stepped Inlet design adds turbulence to the inlet flow, allowing a gradual transition from laminar to turbulent flow. This reduces noise emissions, generates a more massive flow and increases suction power.
Microstructured bypass duct
As the blade tips move through a boundary layer influenced by the presence of a Microstructured Inner Surface, the flow separation that takes place at the suction level becomes almost non-existent.
Integrated anti-vibration dampers
The integrated anti-vibration mounts, made of extra soft silicone, limit the transmission of vibrations while ensuring perfect compatibility with standard fastening systems.
SSO2 Bearing
This is the latest generation of the SSO2 bearing, which is even more optimised. The SSO2 is equipped with a rear magnet closer to the axle for greater precision, durability and stability.
6-year manufacturer's warranty
Noctua fans are renowned for their quality and durability. As with all Noctua models, the NF-A12x25 has an MTBF of over 150,000 hours of testing and is backed by a full 6 year manufacturer's warranty.

    Efficient and .... silent

    The SSO2 bearings feel solid from the weight of the beast. Once plugged in it is quiet and you can feel the ventilation. Very complete package (extension cable, low noise adapter, silenbloc).
