Noctua originally announced and showed off its first liquid cooler last year, promising to bring the same performance and aesthetics of its iconic air coolers to AIOs. Today at Computex 2026, the company has officially unveiled the NL-LC1, putting a name on the lineup that features 240mm, 360mm, and 420mm variants. The NL-LC1 will hit store shelves two weeks later, on June 16, starting at 220 Euros (around $250).
This AIO was originally intended to launch in Q1 2026 but was delayed to Q2 late last year. Hence, we already know most of the details about this product, including the available sizes, mounting, pump solution, fan setup, and more. Most importantly, the NL-LC1 uses Asetek's Emma V2 platform for its pump rather than an in-house solution, but Noctua has developed a custom noise-suppression system around it.
There are three layers of insulation meant to ensure quiet operation, and an integrated mass damper called the "NL-PNA1" (Pump Noise Absorber) to reduce vibrations. Noctua is not only limiting the amount of noise but also ensuring the pitch isn't annoying, even for what little you might be able to hear. The company's own charts show a notable difference with and without the top cover that provides this soundproofing.
The cooler comes with Noctua's legendary NF-A12x25 G2 (120mm) fans for the 240mm and 360mm models, while the 420mm features the NF-A14x25 G2 (140mm) fans instead. Similar to Silverstone's IceMyst Pro coolers we reviewed a couple of months ago, there's also an option for an additional auxiliary fan that can channel airflow to motherboard VRMs, RAM, or M.2 SSDs. It's called the "NL-ACF1" and costs 20 EUR ($23).
Noctua has equipped the NL-LC1 with its SecuFirm2+ mounting system, which supports all current-gen and recent CPUs on the market — AM4, AM5, LGA 1700, and LGA 1851. If you're already using a brown and beige air cooler, it should be a simple swap for you without needing to replace the mounting bracket. Lastly, there are three pump profiles corresponding to different fan speeds and noise levels.
By default, the pump runs at a minimum of 750 RPM, but it can be dialed up to 3,400 RPM manually, using the "Manual" profile. The "Quiet" profile limits the speed to 2,100 RPM, while the "Balanced" profile lets it reach 2,600 RPM. The moment the liquid temperature exceeds 30°C, the Balanced profile will dynamically increase the pump speed up to 3,400 RPM at 45°C to maintain a balance between cooling and noise.
Available from June 16, the NL-CL1 will cost 220 EUR for the 240mm version, 250 EUR for the 360mm version, and 280 EUR for the top-end 420mm version. Converted to USD, that's a ~$250 starting point. Today, you can get high-quality Thermalright AIOs for $50, and spending a bit more will get you their fancy LCD options, too. The 420mm variant comes out to $325 — Arctic's Liquid Freezer III Pro 420 costs around $100, and we gave it a positive review earlier this year.
Even if reviews paint the NL-LC1 in a glowing light, that pricing is a tough pill to swallow for anyone but hardcore Noctua fans. Moreover, it's important to mention that this is different from the pumpless AIO that the company has been showing off. That's still in the prototype stage and not intended for mainstream markets, though the company did say that in the "Quiet" profile, the NL-LC1 is beaten by the pumpless model.
