Noctua fan NF-A12x25-FLX

Noctua NF-A12x25 FLX — Quiet and Powerful Fan

In environments where the balance between efficient cooling and minimal noise is key, the Noctua NF-A12x25 FLX fan is the ideal solution. Thanks to the use of advanced Sterrox® LCP material and ultra-tight clearance between the blades and the frame, the fan provides high cooling performance even at low speeds. With a maximum speed of 2000 rpm (or 1350 rpm when using the U.L.N.A. adapter) and a noise level of only 22.6 dB(A), this fan is a great choice for quiet builds. Its versatile design allows for optimal use for CPU coolers, water radiators or as an additional fan in computer cases.

Flexible speed modes for different needs

The Noctua NF-A12x25 FLX fan supports three speed modes (2000 / 1700 / 1350 rpm) thanks to the included L.N.A. and U.L.N.A. adapters. This flexibility allows users to tailor the noise performance to specific requirements — for example, under high load or in environments where maximum silence is preferred. Thanks to the aerodynamic design and optimized static pressure 2.34 mm H2O, the fan is suitable for applications with strict airflow requirements.

Quality construction and durable materials

The use of patented Sterrox® LCP (liquid crystal polymer) material ensures minimal blade deformation even at high speeds, contributing to long-term stability and performance. The ultra-tight blade clearance allows for maximum airflow efficiency (102.1 m³/h) while minimizing aerodynamic noise. The combination of anti-vibration mounts and radiator seals increases stability and reduces vibration transmission to the surrounding structure.
