Fan Noctua NF-A8 ULN — 80 mm case fan, 12 V, 1100–1400 RPM, 34.8 m³/h, 0.6 W, 6.5–10.4 dB

The Noctua NF-A8 ULN is an 80 mm computer case fan engineered for ultra-low-noise operation. It combines Noctua’s Advanced Acoustic Optimisation (AAO) frame with aerodynamic features such as Flow Acceleration Channels and a refined blade design to deliver effective airflow while minimising turbulence. The ULN (Ultra-Low-Noise) variant runs at reduced speeds (1400 / 1100 rpm) to suit noise-sensitive applications and environments requiring near-silent cooling. The fan measures 80 x 80 x 25 mm, operates at 12 V and comes in Noctua’s brown and beige colour scheme.

Advantages

The NF-A8 ULN offers low operational noise thanks to its ultra-low rotational speeds and aerodynamic optimisations. It features a reference-class SSO2 bearing for long-term running smoothness and reliability. Compact dimensions and efficient airflow performance (approx. 34.8 m³/h) make it suitable for tight spaces where quiet cooling is required. Built to Noctua’s established quality standards, the fan provides a balance of durability and silent operation.

Suitable for

• Small form factor PC cases or builds with 80 mm fan mounts
• Home theatre PCs and media centres where low noise is important
• Noise-sensitive workstations and audio/video production systems
• Replacement or upgrade of existing 80 mm case fans

How to use

Install the NF-A8 ULN into any chassis or device that supports an 80 mm fan mount using the supplied screws or vibration-reducing mounting accessories. Connect the fan to a 3-pin or compatible fan header on the motherboard or to a suitable 12 V fan controller. Ensure correct airflow direction by checking the frame markings or blade orientation, and route the cable to avoid contact with moving parts. If necessary, adjust fan speed via BIOS or an external controller to prioritise quieter operation or increased cooling.

Recommendations

Use the NF-A8 ULN in installations where low acoustic impact is a priority; pairing it with a motherboard fan header that supports voltage or PWM control (with adapter where applicable) allows fine-tuning of speed and noise. Regularly check and clean the fan to maintain performance and longevity.
