Computer case fan Noctua NF-A8 PWM CH.BK.S 80 mm, 4-pin PWM, 450–2200 RPM, 17.7 dB

The Noctua NF-A8 PWM CH.BK.S is an 80 mm computer case fan designed for quiet, efficient cooling in compact systems. It features Noctua’s premium-grade SSO2 bearing with a rated MTTF of over 150,000 hours, PWM speed control from 450 to 2200 RPM, and an all-black chromax.black.swap finish with swappable anti-vibration pads for colour customisation.

Advantages

The NF-A8 PWM chromax.black.swap combines proven low-noise performance and high build quality with an all-black aesthetic and interchangeable red, white, blue, green, yellow and black anti-vibration pads. The fan offers broad compatibility thanks to its 80 × 80 × 25 mm form factor, a wide speed range for controlled airflow, and Noctua’s long warranty and durable SSO2 bearing.

Suitable for

• Compact desktop and small-form-factor PC cases
• Cooling tight spaces where an 80 mm fan is required
• Custom builds where matching fan accents to a colour scheme is desired

How to use

Install the NF-A8 PWM into an available 80 mm mounting location in your case, aligning the airflow direction with your system’s cooling design. Connect the fan to a PWM-capable motherboard header or controller to allow automatic speed regulation. If desired, replace the anti-vibration pads with one of the included colours by removing the existing pads and fitting the chosen pads into the mounting slots.

Recommendations

For optimal noise-to-performance balance, use PWM control to let the motherboard or a fan controller adjust speeds according to system temperature. Ensure the fan is securely mounted with the supplied or compatible anti-vibration mounts and keep fan blades clear of cables and obstructions for maximum airflow and longevity.
