Short Excerpt: Flagship 120×25 mm fan with next-gen aerodynamics and ultra-low noise. Ideal for high-density radiators, tower heatsinks, and case airflow. 2000 RPM max, 22.6 dB(A), ~60 CFM airflow class, SSO2 bearing, Sterrox® LCP impeller, 6-year warranty.
Overview:
The NF-A12x25 PWM fan is a whisper-quiet marvel, engineered with cutting-edge Sterrox® liquid-crystal polymer for unmatched precision and durability. Its unique aerodynamic design ensures top-tier cooling performance—whether it’s battling heat in tight spaces or keeping your case breezy. With integrated anti-vibration pads and an SSO2 (Self-Stabilising Oil-Pressure) bearing, this fan stays smooth and silent. It’s the ultimate choice for discerning builders who demand both power and peace.
Beyond the materials, Noctua’s AAO frame and Flow Acceleration Channels deliver exceptional pressure-to-airflow efficiency, making the NF-A12x25 equally at home on radiators, heatsinks, or as a premium case fan. A generous accessory kit (including a Low-Noise Adaptor, Y-cable, extension, and gasket) rounds out a best-in-class package.
