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.
