Noctua NL-LC1-42 420mm AIO Liquid Cooler

Noctua NL-LC1-42 420mm AIO Liquid Cooler

With first-class cooling performance, superb quietness of operation and industry-leading reliability, the NL-LC1 series brings classic Noctua virtues to the world of all-in-one liquid coolers.

The NL-LC1 series is based on Asetek’s renowned, premium-grade Emma V2 platform, which has established itself as a gold standard for both thermal efficiency and long-term dependability. What makes the NL-LC1 coolers unique is Noctua’s custom-engineered NL-PNA1 pump noise absorber: Leveraging a three-layer acoustic soundproofing structure and the tuned-mass damper effect, the NL-PNA1 reduces both air-borne noise and structure-borne vibrations, which can yield significant improvements in pump acoustics.

For fine-tuning performance-to-noise characteristics, the NL-LC1 series pump integrates a mode switch that allows users to choose between three different pump speed profiles: While the pre-selected quiet mode guarantees that the pump will stay near-inaudible, the balanced mode provides extra performance headroom, and the manual mode gives users full control over the pump’s entire RPM range.

The NL-LC1-42 model combines an extra-large 420mm radiator with three of Noctua’s award-winning NF-A14x25 G2 140mm fans for cutting edge performance-to-noise efficiency and maximum cooling headroom at high heat loads. Working in tandem with the pump noise absorber, the NF-A14x25 G2 flagship fans are the second key factor to the NL-LC1-42’s unique capability of delivering first-rate thermals while running extremely quiet. To ensure a smooth, unobtrusive sound signature, the fans utilise a speed-offset to avoid undesirable harmonics phenomena such as periodic humming or vibration build-up due to beat frequencies.

While the NL-PNA1 pump noise absorber comes with a magnetically attaching metal faceplate, users who require extra ventilation for VRMs, RAM modules, M.2 SSDs or other near-socket components have the option of replacing it with the NL-ACF1 auxiliary cooling fan that is available separately.

Noctua’s proven SecuFirm2+™ mounting system not only enables easy installation, broad socket support and future upgradability, but also helps to improve thermal performance through optimised force transfer and offset mounting options.

Topped off with the proven SecuFirm2+™ multi-socket mounting system, renowned NT-H2 thermal paste and Noctua’s usual 6-year manufacturer’s warranty, the NL-LC1-42 is a deluxe choice for customers who are looking for a premium grade 420mm all-in-one liquid cooler that satisfies the highest demands in terms of performance, reliability and quietness of operation.
