How do you beat a water-cooled gaming PC? With a full immersion PC, of course, where you sink all of your components into a bath of liquid. It’s a technique already used for servers, but Thermaltake showed off a couple of full-immersion gaming PC designs at CES 2025, including a mini-ITX model, and we’re intrigued. While it may seem like anathema to immerse several grands’ worth of electronic components in a case full of liquid, the dielectric coolant used in these systems ensures it won’t conduct any electricity, and it also massively reduces temperatures. In fact, Thermaltake says the systems can reduce CPU and GPU temperatures by around 20°C compared to using one of the best AIO cooler designs.
