Noctua NF-A12x25 5V 120 mm Case Fan, Brown/Beige

The Noctua NF-A12x25 5V is a 120mm fan engineered specifically for applications that operate on a 5V power source, setting it apart from standard 12V PC components. Its aerodynamic design is optimized to produce a balance of static pressure and airflow, making it suitable for both unrestricted case ventilation and environments with impedance, such as behind dust filters. This fan is intended for system builders and integrators working on compact builds, DIY electronics, or other low-voltage setups where conventional 12V fan headers are not an option.

The fan’s construction incorporates Noctua's Sterrox liquid-crystal polymer (LCP) for the impeller, a material selected for its rigidity and stability, which allows for a minimal tip clearance to improve performance. At its core is an SSO2 bearing, a self-stabilising oil-pressure design that contributes to its low noise output and operational longevity. Connectivity is handled by a 3-pin fan connector, and the package includes a USB power adaptor cable, enabling it to be powered directly from a USB port for expanded versatility in custom projects.
