Noctua NL-LC1 AIO coolers arrive with 240mm, 360mm, and 420mm models starting at $219
Noctua has officially stepped into the all-in-one liquid cooling market, and its first AIO lineup is already appearing at retail. After being shown at Computex 2026, the new Noctua NL-LC1 series has surfaced in 240mm, 360mm, and 420mm versions, giving PC builders three premium liquid cooling options designed for high-performance gaming rigs, workstation PCs, and enthusiast builds.
The smallest model, the Noctua NL-LC1-24 240mm AIO, is listed at $219. The larger NL-LC1-36 360mm model is priced at $249, while the flagship NL-LC1-42 420mm version is listed at $279. With these prices, Noctua is clearly positioning the NL-LC1 family in the premium AIO liquid cooler segment, which fits the company’s long-standing reputation for high-end cooling hardware, low noise levels, and long-term reliability.
Compatibility is also broad. The NL-LC1 coolers support major modern desktop CPU platforms, including AMD AM5 and Intel LGA 1700 and LGA 1851 sockets. That makes them suitable for current-generation Ryzen and Core processors, including high-power chips that can benefit from larger radiators and more capable thermal solutions.
At the heart of the Noctua NL-LC1 series is the Asetek Emma V2 pump platform, but Noctua has not simply used it in standard form. The company has applied its own tuning to the pump system, aiming to deliver strong cooling performance while keeping noise and vibration under control. This is one of the key areas where Noctua appears to be leaning into its brand identity, as quiet operation has always been a major selling point for its air coolers and fans.
To reduce pump noise, the NL-LC1 coolers use a three-layer sound insulation system around the pump unit. Noctua has also included an integrated tuned-mass damper, which is designed to reduce vibration transfer into the PC case and tubing. For users who are sensitive to pump hum or unwanted resonance inside a system, these features could make the NL-LC1 lineup especially appealing.
The coolers also offer three selectable pump profiles: Manual, Quiet, and Balanced. This gives users more control over how the cooler behaves depending on their priorities. Quiet mode should appeal to users who want the lowest possible noise during everyday workloads, while Balanced mode is likely aimed at a mix of thermal performance and acoustics. Manual control gives enthusiasts more flexibility to fine-tune pump behavior for their own setup.
Noctua is pairing the radiators with its latest-generation fans. The 240mm and 360mm models use NF-A12x25 G2 fans, while the larger 420mm version uses NF-A14x25 G2 140mm fans. These fans are expected to be a major part of the cooler’s appeal, as Noctua’s NF-A series is widely known among PC builders for strong airflow, static pressure, and low noise output.
The 240mm version should be a good fit for compact or mid-sized builds where case compatibility is more limited. The 360mm model is likely to be the most popular choice for high-performance gaming PCs, offering a larger cooling surface without requiring the space needed for a 420mm radiator. The 420mm NL-LC1, meanwhile, targets users with large cases and high-end processors who want maximum cooling headroom.
Noctua is also preparing an interesting accessory for the NL-LC1 series. The NL-ACF1 auxiliary cooling fan is expected to be offered separately and can replace the magnetic pump faceplate. This small add-on fan is designed to help cool nearby motherboard components, including VRMs, memory modules, and M.2 SSDs. That could be useful because traditional AIO liquid coolers often reduce the airflow around the CPU socket area compared to large tower-style air coolers.
With the NL-LC1 lineup, Noctua is entering a competitive AIO liquid cooling market, but it is doing so with a familiar strategy: premium materials, acoustic tuning, carefully selected fans, and extra attention to vibration control. The pricing makes it clear that these coolers are not aimed at budget builds. Instead, they are designed for users who want high-end CPU cooling with the quieter operating profile that Noctua is known for.
For PC enthusiasts waiting for a Noctua AIO liquid cooler, the arrival of the NL-LC1 series marks a major moment. With 240mm, 360mm, and 420mm options now appearing at retail, builders finally have a liquid cooling alternative from one of the most recognized names in PC cooling.
