Case fan Noctua NF-A8 FLX 80 mm, 12 V, 2000 RPM, 50.4 m³/h, 0.84 W, 25 mm height

The Noctua NF-A8 FLX is a premium 80 mm computer fan engineered for quiet, efficient cooling. It incorporates Noctua’s AAO (Advanced Acoustic Optimisation) frame and aerodynamic improvements such as Flow Acceleration Channels, delivering better static pressure and an improved airflow/noise ratio compared to the NF-R8. The FLX variant includes Low-Noise Adaptors that allow three speed settings (2000 / 1650 / 1200 RPM) so you can balance ventilation performance and near-silent operation. The fan features a refined SSO2 bearing, Smooth Commutation Drive 2 and fully sleeved cables for reliable, long-lasting use.

Advantages

The NF-A8 FLX provides high efficiency in a compact 80×80×25 mm form factor with low acoustic emissions. Flow Acceleration Channels and Inner Surface Microstructures reduce flow separation and vortex noise, while the Stepped Inlet Design improves intake behaviour and suction capacity in confined spaces. Integrated anti-vibration pads lower vibration transmission without affecting compatibility with standard mounting screws. SSO2 bearing and Smooth Commutation Drive 2 ensure smooth rotation, improved stability and extended durability.

Suitable for

• Cooling compact PC cases and small form factor systems
• Case ventilation in systems with restricted airflow paths
• Cooling radiators or components requiring an 80 mm fan
• Silent PC builds where low noise is required

How to use

Install the NF-A8 FLX in your PC or cooling setup using the standard mounting screw holes, taking advantage of the integrated anti-vibration pads for reduced vibration transfer. Connect the fan to a 3-pin header or controller at 12 V and use the supplied Low-Noise Adaptors to set the desired speed (2000 / 1650 / 1200 RPM). Use the 30 cm extension cable if the primary 20 cm cable does not reach the header. Ensure the fan intake and exhaust orientations match your system airflow plan.

Usage recommendations

For optimal results, use the highest speed setting when greater airflow or static pressure is required (e.g., push configuration on radiators or obstructed airflow paths) and lower settings for near-silent operation in general case ventilation. Regularly check for dust buildup and clean as needed to maintain performance and noise characteristics.
