Description
The Noctua NF-A4x10 PWM is an ultra-slim 12V DC Axial Fan with dimensions of 40x40x10mm, ideal for extremely space-restricted cooling applications. It has a nominal voltage of 12V DC and a minimum start-up voltage of 4.5V. The fan has a rated current of 0.04A and a power consumption of 0.48W. Its rotational speed is PWM-controlled, ranging from a minimum of 1000RPM up to a maximum of 4500RPM. It provides a maximum airflow of 8.2m³/h (4.8 CFM) and a maximum static pressure of 17.46Pa (1.78 mmH2O), with a maximum noise level of 17.9dB(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.
