Noctua NF-A14x25r G2 PWM fan

Noctua NF-A14x25R G2 PWM — High-Performance Fan

When cooling CPUs, it is crucial to strike the optimal balance between performance and noise. The Noctua NF-A14x25R G2 PWM achieves this by using Sterrox® LCP technology, which increases strength and reduces blade deformation, and an ultra-tight 0.7 mm blade clearance, which improves aerodynamics. With a maximum speed of 1500 rpm and an airflow of 155.6 m³/h, this fan delivers excellent cooling performance while maintaining a noise level of just 24.8 dB(A). Its round frame measuring 140 × 140 × 25 mm makes it an ideal choice for use on CPU coolers.

Precise control and long life

The fan is equipped with a 4-pin PWM connector that allows intelligent speed control in the range 0-1500 rpm, which brings flexibility in adjusting the performance and noise according to current needs. The optimized P/Q profile ensures that the fan provides consistent performance even under higher loads. The SSO2 (self-stabilizing oil-pressure bearing) extends the lifespan and ensures quiet operation, minimizing wear and vibration.

Aerodynamic design for maximum efficiency

Thanks to innovative aerodynamic features such as ultra-tight clearance blades and a design that minimizes turbulent flow, the NF-A14x25R G2 PWM achieves a high static pressure 2.56 mm H2O. This is ideal for use on CPU coolers and other applications where air resistance needs to be overcome. The fan is also equipped with anti-vibration mounts that reduce the transmission of vibration to the case, which further improves user comfort.
