Product on Review: NL-LC1-36 AIO CPU Cooler
Manufacturer: Noctua
Street Price: USD $250
Noctua’s entry into the all-in-one liquid cooling market has been a long time coming, and the new NL-LC1 series represents the culmination of that effort. Based on Asetek’s flagship Emma V2 platform, the NL-LC1 lineup combines proven liquid-cooling technology with several key Noctua-developed enhancements. The model under review today is the NL-LC1-36, a 360mm all-in-one liquid cooler equipped with three NF-A12x25 G2 fans, positioning it as the middle offering in a range that also includes 240mm and 420mm variants.
What sets the LC1 apart from the crowded AIO market is Noctua’s focus on refining both acoustics and user experience. Alongside the acclaimed NF-A12x25 G2 fans, the cooler incorporates the custom-engineered NL-PNA1 pump noise absorber, designed to further reduce vibration and noise transmission from the pump assembly. Installation is handled by Noctua’s SecuFirm2+ mounting system, a feature that has earned an excellent reputation for ease of use, compatibility and mounting pressure consistency across multiple CPU platforms.
Under the hood, the LC1 benefits from the latest advances of Asetek’s Emma V2 platform. The system features a redesigned pump with a closed impeller design, a high-torque three-phase motor, optimised flow paths and a refined cold plate incorporating a dense skived microfin array. These improvements contribute to higher flow rates, greater pressure head, lower power consumption and smoother operation compared to previous Asetek generations. The package is complemented by a 20 FPI radiator optimised for low-noise operation, high-quality braided EPDM tubing, a carefully formulated coolant mixture for long-term reliability, and comprehensive safety and quality certifications. Noctua backs the LC1 with a six-year warranty, underscoring the emphasis on durability and long-term stability.
In this review, we'll be taking a closer look at the NL-LC1-36 to see how Noctua’s first-generation liquid cooler performs in practice. Testing will focus on two key areas: thermal performance and acoustic behaviour, allowing us to determine whether the LC1 delivers on its promise of combining high-end cooling capability with exceptionally quiet operation.
