Noctua NL-LC1-42 AiO Water Cooling - 420mm, black/brown

The Noctua NL-LC1-42 is not an ordinary all-in-one water cooler, but a finely tuned AiO designed for builds where performance, noise level, and quality must work together uncompromisingly. With a large 420mm radiator, three NF-A14x25 G2 PWM fans, and a dampened pump, it cools particularly powerful CPUs in a controlled manner without overloading your system acoustically.

• 420mm radiator provides enormous cooling surface for powerful processors
• Three NF-A14x25 G2 PWM fans deliver quiet radiator airflow
• NL-PNA1 pump damper reduces disturbing vibrations
• Three pump profiles make it easier to tune to your setup
• SecuFirm2+ ensures secure mounting on current sockets

NL-LC1-42 AiO Water Cooling: Large-Format Cooling with a Delicate Touch

The NL-LC1-42 AiO water cooler is aimed at users who want to run their CPU quietly and reliably even under heavy continuous load. The 420mm radiator offers a particularly large surface area to dissipate heat from the cooling circuit. This helps with demanding gaming, streaming, rendering, and productive workflows when your processor is under sustained stress.

Noctua Fine-Tuning for a Quieter High-End PC

Instead of relying solely on raw cooling power, Noctua combines the AiO with three NF-A14x25 G2 PWM fans and an NL-PNA1 pump damper. The 140mm fans build targeted pressure at the radiator and move a lot of air at controlled speeds. The pump damper reduces vibrations, so your system stays not only cool but also sounds more refined.

More Control for Your Personal Setup

With three pump profiles, you can adapt the cooling to your daily needs. Quiet is suitable for especially silent operation, Balanced offers more reserves for varying loads, and Manual gives you direct control over tuning. The SecuFirm2+ mounting system simplifies installation on AMD AM5 and AM4 as well as Intel LGA 1851 and LGA 1700.
