Noctua NF-A14 5V PWM Fan, 140mm, SSO2 Bearing, Brown/Beige

This 140mm system fan is engineered for effective air movement within computer chassis environments. It features an optimized blade design intended to deliver a maximum airflow of 140.2 m³/h while achieving 2.08 mmH₂O of static pressure. The physical dimensions are standard 140mm x 25mm, making it suitable for integration into standard case mounts. The unit utilizes PBT GF30 material for both the frame and impeller construction, contributing to structural integrity.

Rotational speed is managed via 4-pin Pulse Width Modulation (PWM) control, allowing the fan to operate dynamically between 300 RPM and 1500 RPM. At maximum speed, the fan generates a measured noise level of 24.6 dB, maintaining acoustic neutrality. Crucially, this model is designed specifically for 5V operation, requiring compatibility with appropriate USB or accessory power sources rather than typical 12V motherboard headers. The inclusion of a USB power adapter cable and an OmniJoin adapter set facilitates connection outside of standard PC fan headers.

The operational longevity of the fan is supported by its SSO2 bearing technology, a Self-Stabilising Oil-pressure Bearing system. This bearing type contributes to a high rated Mean Time Between Failures (MTBF) of 150,000 hours. The fan draws a maximum rated current of 0.26 A, resulting in a typical power consumption of 1.3 W.
