The Noctua NF-A14x25 G2 PWM Sx2-PP is a high-performance 140mm case fan designed for enthusiasts and system builders who demand both excellent airflow and quiet operation. Built from Liquid Crystal Polymer (LCP), this fan combines durability with precision engineering. Its classic beige finish reflects Noctua's signature aesthetic, making it a recognizable addition to any build. With PWM support, a maximum rotational speed of 1500 RPM, and a power draw of just 2.28W at 12V, it balances performance and efficiency effectively.
Advanced Bearing Technology
At the heart of this fan is Noctua's Self-Stabilising Oil-pressure Bearing (SSO), a refined magnetic bearing system that keeps the rear of the axle in close contact with a lubricant reservoir. This design ensures consistent rotational stability over time, contributing to smooth, long-lasting operation. The SSO bearing is known for maintaining precision under varying loads and temperatures, making it a reliable choice for continuous use in demanding environments.
Airflow and Acoustic Performance
The NF-A14x25 G2 delivers an impressive airflow of 155.6 m³/h while keeping noise levels at a maximum of 24.8 dB(A), striking a strong balance between ventilation performance and acoustic comfort. The 140x140x25mm form factor fits a wide range of cases and radiators, while the maximum current draw of 0.19A keeps energy consumption low. PWM control allows for dynamic speed adjustment, enabling users to fine-tune the fan's performance to match their specific cooling needs.
