Ventoinha de caixa Noctua NF-A8 PWM — 80 mm, 12 V, 450–2200 rpm, 55,5 m³/h, 17,7 dB, MTBF 150.000 h

The Noctua NF-A8 PWM is an 80 mm computer case fan designed for efficient and quiet cooling. It features Noctua’s AAO (Advanced Acoustic Optimisation) frame, Flow Acceleration Channels and a refined aerodynamic layout to improve airflow and reduce noise compared with earlier designs. The PWM model includes Noctua’s NE-FD1 IC for automatic speed control via 4-pin headers and a Low-Noise-Adaptor that lowers the maximum rpm from 2200 to 1750 when engaged.

Advantages

The fan delivers a wide rotational speed range (450–2200 RPM) and an airflow of up to 55.5 m³/h while maintaining low vibration and smooth operation thanks to the SSO2 bearing. Compact dimensions (80×80×25 mm) and standard 4-pin PWM compatibility make it easy to integrate into cases and cooling setups. The included Low-Noise-Adaptor provides an option to reduce maximum noise and speed for quieter operation.

Suitable for

• Small form-factor PC cases and HTPCs
• Case ventilation and intake/exhaust positions
• Supplementary cooling for GPUs, chipset or VRM areas with compatible mounting
• Systems requiring PWM-controlled fan speed

How to use

Install the fan in the desired case position using the supplied screws or anti-vibration mounts, observing the indicated airflow direction. Connect the 4-pin PWM cable to a compatible motherboard or controller header to enable automatic speed regulation. If lower maximum speed and noise are required, attach the supplied Low-Noise-Adaptor between the fan connector and the header. Ensure the fan is clear of cables and obstructions to maintain optimal airflow.

Recommendations

For balanced cooling and low noise, use the NF-A8 PWM on intake or exhaust positions in small cases and enable PWM control from the motherboard. Fit the Low-Noise-Adaptor when lower peak RPM and reduced acoustic output are preferred.
