NF-A20 PWM Noctua 12V DC Axial Fan

Description

The Noctua NF-A20 PWM is a large 12V DC Axial Fan with dimensions of 200x200x30mm, optimized for quiet and high-performance cooling in PC cases and other applications. It has a nominal voltage of 12V DC and a minimum start-up voltage of 5V. The fan has a rated current of 0.08A and a power consumption of 0.96W. Its rotational speed is PWM-controlled, ranging from a minimum of 350RPM up to a maximum of 800RPM. It provides a maximum airflow of 146.9m³/h (86.4 CFM) and a maximum static pressure of 10.59Pa (1.08 mmH2O), with a maximum noise level of 18.1dB(A). It is equipped with Noctua’s proprietary SSO2 (Self-Stabilising Oil-Pressure) bearing for an MTTF (Mean Time To Failure) of over 150,000 hours. The fan is constructed from fibre-glass reinforced Liquid Crystal Polymer (LCP) and features a 4-pin PWM termination, typically including a Low-Noise Adaptor (L.N.A.) and integrated anti-vibration pads.
