Noctua NL-ACF1 Magnetic Add-on Fan 80 mm

The Noctua NL-ACF1 is a magnetic add-on fan designed specifically for the Noctua NH-P1 passive CPU cooler. It features an 80 mm NF-A8 PWM fan that can be magnetically attached to the cooler, providing active cooling when needed while maintaining the option for passive operation. This fan is ideal for users who want to enhance the cooling performance of their NH-P1 cooler without permanent modifications.

Advantages

Magnetic mounting allows for easy installation and removal without tools. The fan uses Noctua's advanced SSO2 bearing for long-term reliability and quiet operation. PWM support enables automatic speed control from 450 to 2200 RPM, balancing noise and performance. The included Low-Noise Adaptor further reduces noise for near-silent operation.

Suitable for

• Noctua NH-P1 CPU cooler owners seeking additional active cooling
• Users who want a flexible, add-on fan that can be removed for passive mode
• Enthusiasts building quiet, high-performance systems
