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.Get the Noctua NL-LC1-24 240mm Quiet All-in-One Water Cooler on AmazonGet the Noctua NL-LC1-36 360mm Quiet All-in-One Water Cooler on AmazonGet the Noctua NL-LC1-42 420mm Quiet All-in-One Water Cooler on AmazonGiven 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.
