Noctua ready with NF-A12x25 G2

Translate from : Noctua klar med NF-A12x25 G2

These improvements provide a significant improvement in the performance-to-noise ratio, enabling the NF-A12x25 G2 to achieve superior results across a variety of applications, including water-cooling radiators, heatsinks, and case ventilation.

“The first generation NF-A12x25 set a new standard for 120mm fans and has become one of the most successful Noctua fans ever, so we are excited to offer another significant performance boost over this acclaimed model,” says Roland Mossig (CEO of Noctua). “Using the same motor and aerodynamic design strategy as the 14cm G2 model, the new NF-A12x25 G2 has been further refined in almost every area, allowing it to push the boundaries even further in terms of performance and noise efficiency.”

The NF-A12x25 G2 is the improved second generation and successor to the groundbreaking NF-A12x25 and the 120mm sister model to the award-winning 140mm NF-A14x25 G2. Like its acclaimed predecessor, it is made from Sterrox® LCP and has an extremely tight tip pitch of just 0.5mm. At the same time, its further optimized impeller with Progressive Bend, winglets, Flow Acceleration Channels and the new Centrifugal Turbulator Hub enable the G2 version to surpass the performance of the original NF-A12x25, making it Noctua's undisputed new flagship in the 120mm class.

Like its predecessor and the 140mm version, the NF-A12x25 G2 is a true all-rounder, delivering excellent results in all types of use – whether in low-impedance, airflow-focused scenarios such as case ventilation, or high-impedance, static pressure-demanding situations such as heatsinks and water-cooling radiators. For application-specific optimization, the NF-A12x25 G2's AAO (Advanced Acoustic Optimisation) frame can be combined with the included NA-AVG1 anti-vibration gasket for a tighter seal on radiators, or with the optional, separately sold NA-IS1-12 intake-side spacer frame, which can help achieve better intake acoustics and improved airflow in challenging "pull" setups.

Its ultra-efficient etaPERF™ motor with Smooth Commutation Drive 2 technology not only delivers unprecedented energy efficiency and smooth operation, but thanks to the new SupraTorque™ function, it also has extra torque reserve to maintain the desired speed even under back pressure. This ensures even better performance on cooling profiles and radiators.

The fan is available in a standard PWM version with up to 1800 rpm, an ultra-quiet LS-PWM version with up to 1100 rpm, and in an Sx2-PP kit that includes two fans with a speed difference of +/- approx. 50 rpm. This speed offset can be beneficial in push-pull configurations as well as in situations where two or more fans are working side by side – for example, in case ventilation or on radiators – to avoid periodic hum or other unwanted acoustic interference.

Finally, the fan comes with Noctua's reference-class SSO2 bearing, a comprehensive accessory kit and a 6-year manufacturer's warranty. The NF-A12x25 G2 is a premium product throughout. Its superior performance, comprehensive features, advanced construction and cutting-edge materials set a new standard in Noctua's range and make it an elite choice for the most demanding users.
