Noctua NL-ACF1 Auxiliary Cooling Fan
The Noctua NL-ACF1 is a premium auxiliary cooling fan designed specifically to complement Noctua's NL-LC1 series all-in-one liquid CPU coolers. Engineered to restore airflow around the CPU socket that is typically reduced when using liquid cooling, the NL-ACF1 helps lower temperatures on nearby components such as voltage regulator modules, memory modules, and M.2 SSDs. By combining Noctua's renowned acoustic engineering with an innovative airflow-focused design, it delivers additional cooling performance without compromising the exceptionally quiet operation expected from a Noctua product.
Featuring a specially adapted NF-A8 PWM fan, magnetic tool-free installation, and intelligent PWM speed control, the NL-ACF1 integrates seamlessly with all Noctua NL-LC1 liquid coolers. Whether you're building a high-performance gaming system, professional workstation, or overclocked enthusiast PC, it provides an effective way to improve cooling for critical motherboard components while maintaining the refined acoustic profile of your system.
Extra Cooling for Near-Socket Components
Liquid cooling systems naturally reduce airflow around the CPU socket compared to traditional tower air coolers, which can lead to increased temperatures for surrounding motherboard components. The NL-ACF1 is specifically engineered to address this by directing additional airflow across voltage regulator modules, RAM, M.2 SSDs, and other near-socket components, helping to improve thermal stability during sustained high-performance workloads.
Optimised Airflow with Coanda Effect
The NL-ACF1 combines Noctua's proven NF-A8 impeller with a specially developed fan frame that utilises the Coanda effect to direct airflow outwards towards surrounding components. This optimised design distributes cooling more effectively across the motherboard than conventional compact VRM fans, helping maximise cooling efficiency where it is needed most.
Large-Diameter Ultra-Quiet Fan
Unlike many auxiliary cooling solutions that rely on small, high-speed fans, the NL-ACF1 employs a full-size 80mm NF-A8 PWM fan to deliver significantly greater airflow at substantially lower noise levels. The larger impeller also produces a lower-pitched and more pleasant acoustic profile, allowing the fan to provide effective cooling without becoming an audible distraction during gaming or professional workloads.
Intelligent PWM Speed Control
Supporting full PWM control, the NL-ACF1 automatically adjusts its operating speed to match system cooling requirements. Users can also configure fixed fan speeds or synchronise operation alongside other system fans, allowing the auxiliary cooling performance to be tailored for maximum airflow or near-silent operation depending on individual preferences.
Simple Magnetic Installation
Installation is quick and effortless thanks to an integrated magnetic mounting system that securely attaches the NL-ACF1 directly onto the NL-PNA1 pump noise absorber found on compatible NL-LC1 liquid coolers. The tool-free design allows the fan to be installed or removed within seconds while maintaining a clean, factory-integrated appearance.
Premium Noctua Reliability
Built around Noctua's renowned engineering standards, the NL-ACF1 is designed for dependable long-term operation with an MTTF rating exceeding 150,000 hours. Backed by a comprehensive six-year manufacturer's warranty, it delivers the reliability and build quality that enthusiasts have come to expect from Noctua cooling solutions.
Compatibility
The Noctua NL-ACF1 is compatible with Noctua NL-LC1 all-in-one liquid coolers, including the NL-LC1-24, NL-LC1-36, and NL-LC1-42 models. It replaces the standard faceplate fitted to the NL-PNA1 pump noise absorber and installs using the integrated magnetic mounting system without requiring additional tools or modifications.
