Noctua NL-ACF1, Auxiliary Cooling Fan for NL Series Coolers

The NL-ACF1 is an auxiliary cooling fan for Noctua’s NL-LC1 series all-in-one liquid coolers. Installed on top of the CPU block, it provides extra cooling for VRMs, RAM, M.2 SSDs and other near-socket components. Its large, highly optimised NF-A8 impeller delivers significantly more airflow at lower noise levels compared to smaller VRM fans. Leveraging the Coandă effect, the NL-ACF1’s outer frame has been custom-designed in order to draw as much air out towards the components as possible. The fan can be easily adjusted from near-silent operation to maximum cooling via PWM, either at a fixed speed setting or through automatic control by the motherboard. Attaching magnetically to the top of the CPU block, it is extremely straightforward to install. In sum, the NL-ACF1 is a perfect add-on for Noctua NL-LC1 series coolers that are running in systems that could benefit from extra airflow over near-socket components.

• Provides additional airflow around the CPU socket area to improve cooling for near-socket components such as VRMs, RAM or M.2 SSDs
• Compatible with Noctua’s NL-LC1 series all-in-one liquid coolers (NL-LC1-24, NL-LC1-36, NL-LC1-42), easy installation (magnetic snap-on attachment)
• Large NF-A8 80mm fan delivers superior flow rates while running extremely quiet, PWM support for automatic speed control or manual adjustment
• Custom-engineered frame design leverages the Coandă effect to draw more air outwards to reduce component temperatures
• Premium-grade SSO2 fan bearing and MTTF rating of more than 150,000 hours guarantee outstanding longevity
