Noctua NF-A12x25 G2 LS-PWM

The NF-A12x25 G2 LS-PWM is the second generation of Noctua's acclaimed NF-A12x25 120mm fan, building upon the success of its predecessor and the 140mm NF-A14x25 G2. It features Sterrox® Liquid Crystal Polymer (LCP) and an extremely narrow impeller tip clearance of only 0.5mm. Enhanced by an optimized Progressive Bend impeller with winglets and Flow Acceleration Channels, along with a new Centrifugal Turbulator hub, the G2 version surpasses the performance of the original NF-A12x25, establishing itself as Noctua's new flagship 120mm fan.

Like its predecessors, the NF-A12x25 G2 is a versatile all-rounder, delivering excellent results across various applications, from low-resistance case cooling to high-static-pressure scenarios with heatsinks and water-cooling radiators.

For application-specific optimization, the AAO (Advanced Acoustic Optimisation) frame of the NF-A12x25 G2 can be combined with the included NA-AVG1 anti-vibration sealing lip for better sealing on radiators, or the optional NA-IS1-12 spacer for improved acoustics and higher flow rates in demanding "pull" configurations.

The 4-pin LS-PWM version is ideal for semi-passive systems and silent applications requiring near-silent operation and PWM-based speed control, thanks to its PWM support and particularly low speed range. Its highly efficient, low-loss etaPERF™™ motor with Smooth Commutation Drive 2 technology offers unprecedented energy efficiency and superb quietness, impressing even the most noise-sensitive users. The NF-A12x25 G2 is rounded off by Noctua's reference-class SSO2 bearing, a comprehensive accessory package, and a 6-year manufacturer's warranty. Its superior efficiency, future-proof design, and uncompromising material selection set new benchmarks within Noctua's portfolio, making the NF-A12x25 G2 a true premium product for the most demanding requirements.

Next-Generation Performance Level

Building on the success of the original NF-A12x25, the G2 version introduces a refined fan blade geometry and a novel motor design, both contributing to a significant improvement in the performance-to-noise ratio. This allows the NF-A12x25 G2 to achieve superior results in various applications, including water-cooling radiators, heatsinks, and case fan setups.

Highly Optimized P/Q Curve for All Applications

The advanced aerodynamic design of the NF-A12x25 G2 enables an extremely strong pressure-flow (P/Q) curve, particularly in the critical medium range. This makes the NF-A12x25 G2 a true all-rounder, performing excellently in both pressure-sensitive and flow-sensitive applications.

Excellent Application Acoustics

While many fans produce unpleasant, high-frequency noises when mounted in typical applications like coolers or radiators, the NF-A12x25 G2 has been carefully optimized for ideal application acoustics. Even with high back pressure, the fan delivers a smooth, pleasant frequency profile and surprisingly low sound pressure levels.

6-Year Manufacturer's Warranty

Noctua fans are known for their flawless quality and outstanding durability. Like all Noctua fans, the NF-A12x25 G2 features an MTTF specification of over 150,000 hours and comes with a full 6-year manufacturer's warranty.
