Noctua’s highly anticipated AIO cooler is finally available, and PC builders can get it in three sizes — 240mm, 360mm, and 420mm. These all-in-one water-cooling solutions start at $219.95 on Amazon for the smallest 240mm two-fan solution. The larger 360mm version costs $249.95, and is slightly more affordable than the converted European price of US$289.95 (based on the current conversion rate for EUR 250), while the largest 420mm, equipped with three 140mm fans, is priced at $279.95.

Given that this is a Noctua cooling solution, you can expect it to stay silent while still offering performance. It achieves this with the NL-PNA1 pump noise absorber — a mass damper that sits on top of the pump and water block featuring multiple layers of acoustic foam, a dense sound barrier, floating silicone mounts, and an outer shell with a metal faceplate. The pump itself also has three available speed profiles; it’s set by default to quiet mode, ensuring that it remains inaudible during operation. You can set it to balanced mode if you want additional performance headroom at the cost of some noise, while veteran users can switch to manual mode for full control over the AIO.

You can also purchase the optional NL-ACF1 80mm auxiliary cooling fan that mounts directly on the water block. This small add-on can make a big difference to other components, as we saw in Noctua’s booth at Computex 2026. It claims a VRM temperature reduction of nearly 40%, allowing your case fans to run at a slower RPM and further reduce noise. You can check out the Noctua video below if you want to see the company’s deep dive into its first AIO cooling solution.

Aside from these new innovations, the company also includes its legendary A-series fans with the AIO coolers. The 240mm comes with two NF-A12x25 G2 PWM 120mm fans, while the 360mm model boasts three of these fans, which are also found in our best PC case fans of 2026. The larger 420mm AIO trades in the 120mm fans for three NF-A14x25 G2 PWM 140mm fans. All three AIO models are equipped with the SecuFirm2+ mounting system, allowing you to use them on the latest and current-gen sockets on the market, including AM4, AM5, LGA 1700, and LGA 1851. This also means that you can easily swap a Noctua air cooler with this AIO solution if you already use a brown and beige air cooler like the Noctua NH-D15 G2.

The Noctua NL-LC1 series of AIO coolers is admittedly quite expensive, with its starting price of $219.95 on Amazon. This is especially true as there are numerous more affordable options out there, with the best AIO coolers starting at around $120. But if you’re either going for an all-Noctua PC build or want to have a silent PC at all costs, then the Noctua NL-LC1 AIO is your best bet for achieving that.
