Noctua NF-A14x25 G2, 140mm, PWM Fan Kit, 2-pack, Brown/Beige

This product is a dual-pack of 140 mm cooling fans optimized for high-demand thermal management within PC enclosures and liquid cooling radiators. Each fan operates at a maximum rotational speed of 1500 RPM, delivering an airflow volume of 155.6 m³/h (91.58 CFM). The design emphasizes strong static pressure, rated up to 2.56 mmH2O, making the fans suitable for restrictive environments like dense radiators or mesh filters. The inclusion of pulse width modulation (PWM) allows the rotational speed to dynamically scale down to 0 RPM when minimal cooling is required.

Construction utilizes high-grade materials, specifically Liquid Crystal Polymer (LCP) for the impeller, ensuring rigidity and minimizing vibrational distortion during operation. This material choice enables tight blade tip clearance, which contributes to lower operational noise levels, peaking at 24.8 dB at maximum speed. The fans integrate the SSO2 bearing system, rated for a Mean Time to Failure (MTTF) of 150,000 hours, supporting long-term stability across various installation orientations. The set includes necessary cabling accessories for immediate push-pull or side-by-side configurations.
