If you’ve ever built a PC or followed PC hardware trends, you’ve probably heard of Noctua—though maybe not as much outside enthusiast circles. They’re famous among gamers and builders for making some of the quietest and most reliable CPU fans and air coolers around. Up until now, Noctua’s cooling lineup has focused entirely on air cooling, meaning fans and heatsinks that sit directly on your processor to keep it cool. But at Computex 2025, Noctua took a big step forward by showing off its first liquid cooling products—called AIOs, or all-in-one liquid coolers—which use liquid to move heat away from the CPU, generally allowing for better cooling in smaller spaces.
The prototype Noctua cooler they showed was a 360mm AIO with three fans mounted on the radiator. That’s a larger setup usually found on high-end gaming or workstation PCs. They’re also working on 240mm and 420mm versions to fit different case sizes and cooling needs. Noctua hopes to launch these new products sometime in early 2026, though that timing isn’t set in stone.
One standout feature of Noctua’s liquid coolers is their focus on keeping noise levels extremely low. The pump—which circulates the coolant—is based on a popular design by Asetek, but Noctua has added a special three-layer soundproof system plus something called a “tuned-mass damper” that cuts down vibrations. This means the pump should run much quieter than many other liquid coolers you’ll find today. Since Noctua is well-known for quiet fans, it makes sense that they’d want their AIOs to be just as silent.
Another cool addition is a small, optional 80mm fan that can be attached right on top of the pump block. This tiny fan cools nearby components like RAM or SSD drives using something called the Coandă effect—a physics trick where air sticks to curved surfaces, directing airflow precisely where it’s needed most. This is a neat innovation because it helps cool critical parts around the CPU without needing extra fans inside your case.
While PC builders often use Noctua fans on liquid coolers made by other companies, having a Noctua-branded AIO means you can get both your fans and your liquid cooling from a brand known for quality and silence. This could make it easier for people who want a full system from one trusted name. Plus, it might encourage other brands to focus more on making quieter and better-performing liquid coolers, which is good news for all PC enthusiasts.
In short, Noctua’s new liquid coolers are shaping up to be an exciting new option for those who want top-notch CPU cooling without the usual noise. Whether you’re upgrading a gaming rig or building a powerful workstation, these upcoming AIOs could deliver strong performance while staying whisper-quiet. We’ll have to wait until 2026 to see the finished products, but the preview at Computex has certainly set the stage for a new chapter in Noctua’s cooling legacy.
