Exceptional Cooling Performance:

Experience superior cooling with the Noctua NF-A12x25 FLX fan. This 120mm fan is meticulously engineered for optimal performance in various cooling scenarios. It provides a robust airflow of 102.1 m³/h and a high static pressure of 2.34 mm H₂O. These capabilities ensure efficient heat dissipation, even through restrictive heatsinks or tight spaces. Consequently, your components remain cool and stable, enhancing overall system reliability.

 

Advanced Blade Geometry for Enhanced Airflow:

The NF-A12x25 features Noctua’s signature A-series blade geometry, complete with Flow Acceleration Channels. This innovative design optimizes airflow distribution and reduces airflow separation. As a result, it leads to improved cooling efficiency and lower turbulence noise. The precision-engineered blades ensure that air moves smoothly and effectively, maximizing cooling potential for your system.

Ultra-Quiet Operation:

Despite its powerful performance, the Noctua NF-A12x25 operates with remarkable quietness. It produces an acoustical noise level of just 22.6 dB(A) at full speed. This makes it an excellent choice for noise-sensitive applications and silent PC builds. The fan’s advanced aerodynamic design and high-quality construction contribute to its exceptionally low noise profile, ensuring a peaceful computing environment.

Premium Durability and Versatile Application:

The Noctua NF-A12x25 FLX fan is built to last, featuring premium materials and a robust bearing system. Its versatile design and included accessories make it suitable for a wide range of applications, providing both reliability and adaptability for various projects. This fan is engineered for long-term, consistent performance.

 

Sterrox® LCP Material for Superior Longevity:

Constructed from Noctua’s proprietary Sterrox® Liquid-Crystal Polymer (LCP) compound, the NF-A12x25 offers exceptional tensile strength, low thermal expansion, and outstanding dimensional stability. This advanced material allows for extremely tight tip clearance (0.5mm) between the blade tips and the frame. This further enhances performance and reduces noise. Consequently, the fan maintains its structural integrity and performance over many years of operation.

SSO2 Bearing for Extended Lifespan:

The fan incorporates Noctua’s renowned SSO2 bearing system. This optimized second-generation self-stabilizing oil-pressure bearing provides superior long-term stability and quiet operation. With an impressive MTTF (Mean Time To Failure) exceeding 150,000 hours, the NF-A12x25 is designed for continuous, reliable performance, backed by a 6-year manufacturer’s warranty. Therefore, you can trust in its enduring quality.

Flexible Low-Noise Adaptors for Speed Control:

The NF-A12x25 FLX comes with Low-Noise Adaptor (L.N.A.) and Ultra-Low-Noise Adaptor (U.L.N.A.). These allow you to precisely control the fan’s speed and noise levels. The L.N.A. reduces rotational speed to 1700 RPM (18.8 dB(A)), while the U.L.N.A. further lowers it to 1350 RPM (14.2 dB(A)). This flexibility enables you to prioritize either maximum cooling or whisper-quiet operation, tailoring the fan’s performance to your specific needs.
