Next-Generation Performance with Sterrox® LCP
The Noctua NF-A14x25 G2 PWM is engineered to provide uncompromising cooling performance. Its design focuses on maximizing airflow and static pressure. This ensures efficient heat dissipation in demanding scenarios. Consequently, this fan is ideal for high-density cooling applications. It maintains optimal temperatures for critical components.
Revolutionary Sterrox® LCP Material
This fan utilizes Noctua’s proprietary Sterrox® LCP (Liquid-Crystal Polymer) material. This advanced polymer offers exceptional tensile strength and low thermal expansion. It allows for extremely tight tip clearances between the fan blades and the frame. This significantly enhances aerodynamic efficiency. Furthermore, it reduces leakage flows. Therefore, the fan delivers superior performance, especially in pressure-demanding applications like radiators and heatsinks.
Advanced Aerodynamic Design with Flow Acceleration Channels
The NF-A14x25 G2 PWM features Noctua’s A-Series blade geometry. It incorporates Flow Acceleration Channels. These precisely guide the airflow. This enhances efficiency and reduces turbulence. Additionally, the AAO (Advanced Acoustic Optimisation) frame technology further contributes to its superior performance-to-noise ratio. Consequently, the fan delivers optimized airflow with minimal acoustical noise, providing effective cooling without distraction.
Innovative Motor Technologies and Whisper-Quiet Operation
The Noctua NF-A14x25 G2 PWM integrates cutting-edge motor technologies. These ensure exceptional energy efficiency and silent operation. Its advanced bearing system contributes to long-term reliability. Consequently, this fan provides dependable cooling and durability, even in continuous operation within sensitive environments, maintaining a remarkably low noise profile.
etaPERF™ Motor for Energy Efficiency
This fan features Noctua’s innovative etaPERF™ motor. This motor sets new standards in energy efficiency. It provides superior performance per watt consumed. Additionally, SupraTorque™ technology leverages torque headroom. This boosts pressure performance. Therefore, the fan delivers powerful cooling while minimizing power draw, contributing to a more eco-friendly and cost-effective system.
SSO2 Bearing for Extended Life Expectancy and Low Noise
The NF-A14x25 G2 PWM incorporates Noctua’s renowned SSO2 bearing. This second-generation self-stabilizing oil-pressure bearing ensures superior long-term stability and incredibly quiet operation. It boasts an impressive MTTF (Mean Time To Failure) of over 150,000 hours. Therefore, this fan provides exceptional reliability and a prolonged operational lifespan, minimizing the need for replacements while maintaining a low acoustical noise level of 24.8 dB(A).
Versatile Compatibility and Comprehensive Accessories
The Noctua NF-A14x25 G2 PWM offers broad compatibility for various cooling setups. Its standard dimensions and connectivity ensure easy integration into most systems. Furthermore, it comes with a comprehensive set of accessories. These enhance installation flexibility and optimize acoustics. Consequently, this fan provides a complete and adaptable cooling solution for any PC build.
Standard 140mm Size and 4-pin PWM Control
With dimensions of 140x140x25 mm and standard 124.5×124.5 mm mounting hole spacing, the NF-A14x25 G2 PWM fits most 140mm fan mounts. It connects via a 4-pin PWM connector. This allows for automatic speed control through your motherboard or fan controller. Therefore, you can precisely manage fan speed based on system temperatures, balancing performance and acoustics effectively.
Included Low-Noise Adaptor and Anti-Vibration Mounts
The fan comes with a NA-RC16 Low-Noise Adaptor (L.N.A.). This reduces the maximum rotational speed to 1250 RPM, lowering acoustical noise to 19.7 dB(A). Additionally, it includes NA-AV2 anti-vibration mounts and NA-AVG2-LR anti-vibration gaskets. These minimize vibration transmission to the case. A 4-pin PWM splitter cable and extension cable are also provided. Therefore, you can fine-tune the fan’s performance and acoustics to perfectly match your system’s requirements, ensuring a quiet and stable operation.
