Description

The Noctua NL-LC1-42 420mm All-In-One liquid cooling system brings the classic, timeless virtues of the iconic company to the world of closed-loop liquid cooling, combining pioneering performance with unprecedented silent operation. Based on the highly mature and proven reliable Asetek Emma V2 platform, it offers top-tier heat dissipation even for the most demanding processors on the market. It is the world's first AIO system to integrate the innovative NL-PNA1 pump noise absorption system, which simultaneously eliminates airborne noise and vibrations. Equipped with the SecuFirm2+™ mounting system based on Torx® screws, it offers broad compatibility with modern Intel and AMD sockets. At the same time, the three premium 140mm NF-A14x25 G2 PWM fans guarantee top airflow with the lowest possible noise level. It is the ultimate choice for users seeking the highest build quality and the guaranteed reliability of Noctua.

Tested Asetek Emma V2 Platform & Top Performance

The Noctua NL-LC1-42 liquid cooling series is based on the advanced Asetek Emma V2 platform, leveraging over two decades of Asetek's expertise in All-In-One systems. It represents the latest and most mature evolution of a proven system, offering top-tier heat dissipation performance and unmatched long-term reliability. It ensures the processor temperatures remain exceptionally low, even under extreme workload conditions or demanding overclocking.

Innovative NL-PNA1 Pump Noise Absorber

The NL-LC1 is the world's first AIO liquid cooling series to incorporate the NL-PNA1 pump noise absorption system. Utilizing a dual operating principle that combines acoustic insulation with tuned-mass damper technology, it manages to drastically reduce both the airborne noise of the pump and the vibrations transmitted to the chassis. The result is an almost silent operation that redefines the standards in the liquid cooling category.

Multifunctional SecuFirm2+™ Mounting System

Utilizing Noctua's renowned installation ecosystem, the SecuFirm2+™ system based on Torx® screws offers an exceptionally stable, secure, and easy mounting process. It ensures full compatibility with the latest AMD AM5 and AM4 sockets, as well as Intel LGA1851/1700, while maintaining the company's tradition of timeless support and easy transition from air cooling to liquid cooling. Its manufacturing excellence guarantees perfect pressure distribution on the processor.

Top NF-A14x25 G2 PWM 140mm Fans

The NL-LC1-42 system includes three award-winning flagship NF-A14x25 G2 PWM fans with a diameter of 140mm. They incorporate all the latest technological innovations from Noctua, including speed offset to eliminate unwanted resonance phenomena, offering unparalleled airflow and static pressure. These premium fans form the cornerstone of the unmatched performance-to-noise ratio provided by the 420mm radiator.

Tube Length

The Tubing Length (mm) indicates how long the tubes connecting the pump to the radiator of the liquid cooling system are, and it directly affects the ease of installation inside the case. A longer length offers more flexibility in radiator placement (e.g., in large cases or in different positions such as the top or front), while a shorter length results in a more “compact” setup but with limited placement options.

  • High (1800+ RPM): Maximum airflow, suitable for demanding conditions or overclocking, with increased noise.
Air Flow
274.74 cfm

Air Flow

Airflow (CFM) indicates the volume of air that the fan moves per minute (Cubic Feet per Minute) and directly affects the cooling performance of the radiator. The higher the value, the more air passes through the radiator, contributing to better heat dissipation, although it is usually accompanied by increased noise.
Air Pressure
2.56 mmH₂O: millimeters of water

Air Pressure

Air Pressure (mmAq) indicates the force with which the fan pushes air through obstacles such as the radiator and is measured in mm of water column. The higher the value, the better the fan can penetrate the dense fins of the radiator, making it more efficient for water cooling compared to regular case fans.
