The NF-A12x25 G2 is Noctua’s second-generation flagship 120 mm fan, constructed from Sterrox liquid-crystal polymer and engineered with an exceptionally tight 0.5 mm tip clearance. Its refined Progressive-Bend impeller—with integrated winglets—Flow Acceleration Channels, and a Centrifugal Turbulator Hub work in concert within Noctua’s Advanced Acoustic Optimisation frame to boost aerodynamics and lower noise across both high-airflow and high-static-pressure applications. Powering this design, the new etaPERF motor—featuring Smooth Commutation Drive 2 and SupraTorque™ technology—provides increased torque headroom to maintain target RPM under back-pressure, ensuring stable performance on heatsinks, radiators, and in chassis configurations alike.

Offered in three variants—a PWM model up to 1,800 rpm, an LS-PWM version capped at 1,100 rpm for quieter operation, and an Sx2-PP dual-fan set with a ±50 rpm offset to minimize acoustic interference in push–pull setups—the NF-A12x25 G2 caters to diverse cooling needs. Priced at €34.90 (USD 34.90) for single-fan PWM and LS-PWM editions and €64.90 (USD 64.90) for the Sx2-PP package, each unit ships with anti-vibration mounts, inlet-spacer and gasket accessories, and is backed by Noctua’s six-year warranty, underscoring its premium positioning in the market.
