Next-generation 140mm fans introduced by Noctua: NF-A14x25 G2s claim enhanced performance, maintain consistent color
In the realm of PC cooling, Noctua has recently unveiled its next-generation 140mm case and cooler fan, the NF-A14x25 G2. This new addition to the Noctua family presents several key performance enhancements and design attributes, focusing on both airflow and noise reduction, particularly for radiator cooling applications.
### Improved Performance-to-Noise Ratio and Advanced Impeller Design
The NF-A14x25 G2 delivers an unparalleled performance-to-noise ratio within the 140mm fan category, optimized especially for radiator cooling. This means it provides higher airflow and static pressure at lower noise levels compared to the original NF-A14 series, which is critical for efficient liquid cooling setups.
The G2 series fans feature a refined impeller with a "Progressive-Bend" shape, which enhances static pressure and airflow efficiency, enabling better thermal performance with quieter operation.
### Optimized RPM and Airflow
The NF-A14x25 G2 spins up to 1800 RPM, which is slightly lower than some high-speed fans but sufficient to achieve strong airflow results. This balance improves acoustic comfort while maintaining effective cooling performance akin to or better than the first-generation NF-A14 fans.
### Award-Winning Recognition
The NF-A14x25 G2 series received the Best Fan Series Award at Computex 2025, underscoring its industry-leading status in performance and design innovation.
### Durability and Quality
Building on the robust manufacturing quality Noctua is known for, the G2 model incorporates refined construction that maintains longevity and stable performance over time, ideally suited for high-demand PC cooling contexts.
### The Sx2-PP Set and Pricing
There is an Sx2-PP set with dual fans that maintain a ~25 RPM offset, aimed toward fans in push-pull configurations or other side-by-side configurations. The Sx2-PP set includes dual fans, retailing for $76.90, providing a slight net discount on the second fan.
The MSRP for both the standard and ultra-quiet versions of the NF-A14x25 G2 is $39.90. The NF-A14x25 G2 is available in Noctua's signature brown color scheme.
For case cooling at 1500 RPM, the original NF-A14 could only achieve about 68 CFM, while the new NF-A14x25 G2 can reach up to 78.5 CFM. The NF-A14x25 G2 succeeds the original 2013 Noctua NF-A14 and its PWM variant.
The NF-A14x25 G2 is a versatile fan that performs well in both low-impedance and high-impedance applications. However, no information is provided about the availability of the chromax.black variant of the Sx2-PP set or the NF-A14x25 G2.
In summary, the NF-A14x25 G2 fans elevate the original NF-A14 design by boosting airflow efficiency with smarter blade geometry, delivering quieter operation at similar or better speeds, and enhancing suitability for radiator cooling. These improvements make the G2 a top-tier choice in the 140mm fan segment, recognized by industry awards and praised for balanced performance and acoustics.
In the world where technology advances rapidly, the latest addition to Noctua's family, the NF-A14x25 G2, stands out as a smart-home-device for PC cooling. This gadget, designed with improved performance-to-noise ratio and advanced impeller design, not only incorporates sleek gadgetry but also enhances the thermal performance of radiator cooling applications.
