Noctua Launches Next-Generation 120mm Flagship Fan: NF-A12x25 G2, with Significant Improvements in Quietness and Performance

The Austrian cooling specialist's latest offering sets a new benchmark in noise reduction and cooling efficiency.

Austrian cooling manufacturer Noctua has officially launched its next-generation 120mm flagship fan series, the NF-A12x25 G2. This highly anticipated product is a comprehensive upgrade over its predecessor, significantly improving the performance-to-noise ratio and offering a new option for users seeking quiet and efficient cooling .

The new fan features a redesigned impeller and motor hub, increasing airflow by approximately 9% under the same pressure compared to the previous generation. Meanwhile, under specific operating conditions, noise levels can be reduced by 1.5 to 3.5 decibels .

01 Three Technical Innovations for a Quieter, Cooler Experience

The success of the NF-A12x25 G2 is no accident; it's built on several core technological breakthroughs from Noctua.

The fan utilizes a patented Sterrox liquid crystal polymer (LCP) material for the impeller, which offers higher tensile strength and lower thermal expansion than traditional thermoplastics . The impeller design incorporates an aerodynamically optimized swept-back design with flow acceleration channels, and the tip clearance between the blade and the frame is minimized to only 0.5mm, significantly reducing airflow leakage .

For the motor, the NF-A12x25 G2 is equipped with a novel Neodymium magnet driven motor, contributing to its enhanced performance . Noctua's proprietary SSO2 bearing technology is also retained, ensuring long-term stable operation .

The inner frame's microstructures have been optimized, such as a more gradual stepping of the three-layer inner edge and increased depth of the small triangular notches on the frame's interior. These details collectively enhance intake efficiency and noise reduction .

02 Performance Parameters Comparison, Tangible Upgrades

The standard PWM version of the NF-A12x25 G2 has a maximum speed reduced from the previous generation's 2000 RPM to 1800 RPM, yet performance has actually improved .

Maximum airflow increased from 102.1 m³/h to 107.3 m³/h, and maximum static pressure rose from 2.34 mm H₂O to 3.14 mm H₂O . The maximum noise level is stated as 22.5 dB(A), which can be further reduced to 18.1 dB(A) using the included low-noise adapter .

According to Noctua's internal testing, under a 200W thermal load, the NF-A12x25 G2 performed 3.5 degrees Celsius better than the original NF-A12x25 on a 120x49mm heatsink, with both operating at similar noise levels .

03 Three Versions Available to Meet Different Needs

The NF-A12x25 G2 series is offered in three versions to cater to different user requirements .

The standard PWM model, with a maximum speed of 1800 RPM, is suitable for users seeking balanced performance. The LS-PWM low-speed version, with a maximum speed of 1100 RPM, is designed for users pursuing ultimate quietness. The Sx2-PP dual-fan kit includes two fans with slightly tuned speeds (±50 RPM), which can reduce acoustic resonance when multiple fans are operated side-by-side .

The speed difference between the two fans in the Sx2-PP kit is designed to minimize resonance and lower noise, particularly beneficial for push-pull or side-by-side configurations .

Regarding pricing, the standard and low-speed versions are priced at $34.90 each (approximately RMB 250), and the dual-fan kit is priced at $64.90 (approximately RMB 465) . Noctua provides a six-year warranty for this new fan .

04 Market Positioning and Future Plans

The launch of the NF-A12x25 G2 solidifies Noctua's position in the high-end cooling market .

Noctua also plans to launch a full-black "Chromax" version in the first quarter of 2026, catering to users with different aesthetic preferences . Furthermore, the NF-A12x25 G2 is expected to be a core component of Noctua's first all-in-one liquid cooler, which is anticipated to launch in the first quarter of 2026 .
