Noctua NF-A6X25 PWM 60 mm Case Fan - Beige/Brown

The Noctua NF-A6X25 PWM is a 60x25 mm fan designed for applications that require a combination of focused airflow and quiet operation. It incorporates specific aerodynamic features, such as Flow Acceleration Channels on the blades, to improve airflow efficiency and reduce noise signatures. The fan utilizes an SSO2 bearing, a self-stabilizing oil-pressure bearing, which is engineered for operational longevity and consistent rotational stability. Its frame and impeller are constructed from PBT GF30, a type of fibre-glass reinforced thermoplastic material selected for its durability.

This model features a 4-pin PWM connector, enabling motherboards to automatically adjust the fan's rotational speed based on system thermal loads. The speed ranges from 550 to 3000 RPM, providing a functional balance between cooling performance and acoustic output. Its standard 60 mm dimensions make it suitable for installation in compact PC cases, small form factor (SFF) builds, and other space-constrained enclosures. The package includes a Low-Noise Adaptor (L.N.A.) that can be attached to limit the maximum fan speed for systems prioritizing minimal noise.
