NF-A4x10 PWM fan
12 V / 40x40x10mm

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 40x40x10mm dimensions ensure that it can replace most existing fans seamlessly, while the controlled airflow with only about 19.6 dBA noise produces a steady airflow of 0.15 m³/min, thanks to the well-placed grooves in the AAO (Advanced Acoustic Optimisation) frame. The PWM version has a variable turning speed and comes with a six year warranty.
