Noctua NF-A12x25 G2 PWM chromax.black 120mm fan Black

Noctua NF-A12x25 G2 PWM chromax.black 120mm fan Black overview

Award-winning NF-A12x25 G2 design

Providing a significant performance boost over the renowned first-generation NF-A12x25, the NF-A12x25 G2 has become a new favourite among quiet cooling enthusiasts. With rave reviews and dozens of awards from hardware media around the world, the G2 model is a proven premium choice for the highest demands.

chromax.black edition

From the impeller and fan frame to the anti-vibration pads, anti-vibration gasket, anti-vibration mounts, screws and cables, the chromax.black edition is black from head to toe, making it easy to integrate into all-black PC builds and various other environments.

Colour-customisable with optional accessories

The chromax.black edition can be colour-customised by replacing the four black NA-AVP1 anti-vibration pads on the inlet side with other colours that are available separately (e.g. white, grey, brown or red). For additional customisation, Noctua’s chromax line also comprises cables and anti-vibration mounts in various colours.

Highly optimised P/Q curve for all applications

The NF-A12x25 G2’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 G2 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications.

Excellent on-application acoustics

While many fans produce unpleasant, high-pitched noises when installed in typical applications such as on heatsinks or radiators, the NF-A12x25 G2 has been carefully fine-tuned for optimal on-application acoustics. It produces a smooth, pleasant frequency profile and surprisingly low sound pressure levels (SPL) when working against back pressure.

Progressive-Bend impeller

The NF-A12x25 G2 features a unique Progressive-Bend impeller with Flow Acceleration Channels and winglets. Its nine blades are swept backwards close to the hub and progressively bent forward further out. Working in tandem with the Centrifugal Turbulator hub, this design not only helps to push more air towards the outer blade areas where efficiency is higher but also assures maximum lift and near uniform loading across the entire blade span.

Centrifugal Turbulator hub

Acting as a turbulator, the new Centrifugal Turbulator hub design improves flow attachment in the hub region. At the same time, its centrifugal driving motion pushes air outwards from the hub area where efficiency is low due to the slow rotational speed towards the outer, high-efficiency zones of the blades, thereby increasing overall efficiency by optimising fluid distribution across the impeller area.

Flow Acceleration Channels

The NF-A12x25 G2 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.
