120 mm Noctua NF-A12x15 PWM slim case fan, 15 mm thickness, 12 V, PWM, 450–1850 RPM, 94.2 m³/h, 23.9 dB, SSO bearing

The Noctua NF-A12x15 PWM CH.BK.S is a premium slim 120 mm case fan that combines high-performance quiet cooling with a compact 15 mm profile. It features Noctua’s SSO2 self-stabilising oil-pressure bearing, a rated MTTF of over 150,000 hours and a 6-year manufacturer’s warranty. The chromax.black.swap edition offers an all-black finish and a set of self-adhesive anti-vibration pads in red, white, blue, green, yellow and black for colour customisation to match individual builds.

Advantages

The fan provides a wide speed range (450–1850 RPM) for flexible control via PWM, delivering up to 94.2 m³/h airflow and a maximum static pressure of 1.53 mmH2O while maintaining low noise thanks to the SSO2 bearing and aerodynamic design. Its 120 x 120 x 15 mm slim form factor allows installation in tight spaces without sacrificing performance, and the included chromax.swap pads enable simple visual customization and reduced vibration transfer.

Suitable for

• Compact PC cases and slim form-factor builds
• Radiator or heatsink setups requiring a slim 120 mm fan
• Users seeking quiet, PWM-controlled case cooling
• Custom builds where black components and colour accents are desired

How to use

Install the fan in your case or on a radiator using the appropriate screws, ensuring correct airflow direction. Connect the 4-pin PWM cable to a motherboard fan header to allow automatic speed control. Attach the included chromax.black.swap anti-vibration pads to the fan corners as desired to match your build’s colour scheme and to reduce vibration transfer. Follow Noctua’s mounting guidelines for radiator and heatsink configurations when replacing or adding fans.

Recommendations

The NF-A12x15 PWM CH.BK.S is recommended for situations where a slim, high-quality 120 mm fan is required: narrow case mounts, low-profile coolers and radiators. Use PWM control for balanced acoustics and performance, and apply the supplied anti-vibration pads if reducing noise transfer or customising appearance is important.
