NF-A4x20 FLX fan
12 V / 40x40x20mm

Tired of the loud noise when working on your computer, 3D printer or any other device? This premium quality silent fan by Noctua is the perfect solution! The integrated shock absorbers and SS02 bearings will reduce the sound level and provide more stability, with a longer life-time. The 40x40x20mm dimensions ensure that it can replace most existing fans seamlessly, while the controlled airflow with only about 14.9 dBA noise produces a steady airflow of 0.16 m³/min, thanks to the well-placed grooves in the AAO (Advanced Acoustic Optimisation) frame. The FLX version has a fixed turning speed and comes with a six year warranty.
