Noctua NF-A12x25 G2 LS-PWM

Premium-Quality Quiet 120mm PC Fan

Product Overview

The NF-A12x25 G2 is the second-generation, further improved successor to the groundbreaking NF-A12x25 and 120mm sister model to the award-winning 140mm NF-A14x25 G2. It is made from Sterrox® LCP and features an extremely tight tip-clearance of only 0.5mm. Its further optimised Progressive Bend impeller with winglets, Flow Acceleration Channels, and the new Centrifugal Turbulator Hub enable the G2 version to surpass the original NF-A12x25's performance, making it Noctua's undisputed new flagship in the 120mm range.

The NF-A12x25 G2 is a true all-rounder that yields superb results in all types of usage, regardless of whether it's in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, static pressure demanding scenarios such as on heatsinks and water cooling radiators.

The 4-pin LS-PWM version is a low-speed, PWM-enabled variant that is ideal for semi-passive setups or ultra-low-noise applications that require near-silent acoustics and PWM based speed control. Its super-low-loss etaPERFTM motor with Smooth Commutation Drive 2 technology combines unprecedented energy efficiency with superb running smoothness.

Topped off with Noctua's reference-class SSO2 bearing, a rich bundle of accessories, and a 6-year manufacturer's warranty, the NF-A12x25 G2 is a premium-quality product through and through.

Next-generation performance

Building upon the success of the original NF-A12x25, the G2 version introduces a refined blade geometry and a novel motor design, both of which enable a significant boost in performance-to-noise efficiency. This enables the NF-A12x25 G2 to achieve superior results across various applications, including water cooling radiators, heatsinks, and case fan setups.

Highly optimised P/Q curve for all applications

The NF-A12x25 G2's sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 G2 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications.

Excellent on-application acoustics

While many fans produce unpleasant, high-pitched noises when installed in typical applications such as on heatsinks or radiators, the NF-A12x25 G2 has been carefully fine-tuned for optimal on-application acoustics. It produces a smooth, pleasant frequency profile and surprisingly low sound pressure levels (SPL) when working against back pressure.

6-year manufacturer's warranty

Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A12x25 G2 features an MTTF of more than 150,000 hours rating and comes with a full 6-year manufacturer's warranty.
