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.

Ultra-tight tip clearance
The NF-A12x25 G2 has an extremely tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design helps the NF-A12x25 G2 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame.

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.
