Noctua NF-A8 PWM - Ventoinha de caixa - 80 mm

The NF-A8 PWM stands apart from typical 80mm fans by combining Noctua’s award-winning SSO2 bearing with an advanced PWM control IC, delivering whisper-quiet operation without sacrificing airflow. Where standard fans whine or click, this model uses flow acceleration channels and stepped inlet geometry to push air smoothly, making it ideal for CPU coolers, case ventilation, or any space-constrained build that demands acoustic refinement.

Highlights

• 80mm square frame with A-series blade geometry for superior static pressure
• 4-pin PWM connector with NE-FD1 IC for automatic speed control from 450 to 2200 RPM
• Includes Low-Noise Adaptor, Y-cable, 30cm extension, anti-vibration mounts, and screws
• SSO2 bearing rated for over 150,000 hours of continuous operation
• Maximum airflow of 55.7 m³/h (32.7 CFM) at only 17.7 dB(A)

In daily use

At full speed the NF-A8 PWM remains discreet, but its true strength emerges under partial load. The PWM control allows motherboards to dial the fan down to 450 RPM, where noise drops below the threshold of perception while still maintaining gentle airflow. The included Low-Noise Adaptor further caps the maximum speed for users who prioritise silence over peak cooling. Anti-vibration mounts made of soft silicone eliminate any residual hum when mounted directly to a case panel.
