The Noctua NF-A14x25 G2 LS-PWM is a 140 mm computer case fan designed for efficient cooling with minimal noise. This successor model achieves a maximum speed of 800 revolutions per minute and offers an airflow capacity of 48 cubic feet per minute at a low noise level of 11.4 dB. The PWM control function allows for precise speed adjustment according to the cooling requirements of the system. With a diameter of 140 mm and a standardized mounting hole pattern, this fan is compatible with most computer cases and cooling systems designed for 140 mm fans. The beige-brown color scheme is complemented by advanced aerodynamic design elements, including flow acceleration channels and a stepped inlet design for improved airflow efficiency. The motor utilizes SSO2 bearing technology for quiet operation and long-term reliability. The low-speed variant is optimized for applications where quiet operation is prioritized while still providing adequate cooling performance. The fan features a standardized 4-pin PWM connector for motherboard compatibility and includes anti-vibration mounts to reduce resonance transfer to the case structure. Suitable for use in desktop computer systems, workstations, and other computing applications that require reliable air circulation with minimal acoustic disturbance.
