Computer case fan Noctua NF-A6x25 5V — 60 mm, 3000 RPM, 29.2 m³/h, white

Noctua NF-A6x25 5V is a 60 mm white computer case fan engineered for low-voltage 5 V systems. With a compact 60×60×25 mm frame it delivers up to 3000 RPM, an airflow of 29.2 m³/h and a maximum static pressure of 2.18 mmH2O. The design combines a reduced motor hub, Flow Acceleration Channels, AAO frame features and Noctua’s Smooth Commutation Drive and SSO2 bearing to provide efficient cooling, low noise and long-term stability in small-form-factor PCs, routers, NAS devices and other 5 V applications.

Advantages

The NF-A6x25 5V offers high aerodynamic efficiency from Flow Acceleration Channels and a reduced motor hub that increases blade surface area for improved airflow and pressure. Noctua’s AAO frame with Stepped Inlet Design and Inner Surface Microstructures refines intake behaviour and reduces vortex and tonal noise. Integrated anti-vibration pads minimise vibration transmission while maintaining standard mounting compatibility. Smooth Commutation Drive and the SSO2 bearing ensure smooth, reliable operation and long service life, and the included OmniJoin™ adaptor set plus polarity protection make the fan easy and safe to integrate into many proprietary 5 V systems.

How to use

Install the NF-A6x25 5V into a compatible 60 mm mounting location using standard screws or fan clips. Connect the fan to a 5 V supply or to a proprietary fan header using the included OmniJoin™ adaptor set following the adapter instructions; cut the original cable if required and use the supplied Scotchlok™ connectors to join wires securely. Observe the integrated polarity protection but check pin alignment where documentation is available. Ensure the fan has sufficient clearance for airflow and that anti-vibration pads contact the chassis or mount to reduce transmitted vibration.

Recommendations

For best results in restricted spaces, mount the fan so that the airflow path is unobstructed and consider using it in push or pull configurations depending on case layout. Regularly check connectors and cable routing to avoid contact with rotating blades. The fan’s white finish suits visible installations where colour matching is relevant.
