We are watercooling a PC using his pool. That's right, even the hottest components like the Intel Core i9-13900K or the RTX 4090 will be easily cooled by the sheer amount of water. But can we cool Linus' hubris? Also, is this actually going to work?

This video documents the third installment in Linus Tech Tips’ ambitious project to watercool a PC using a pool, set in Linus’ new house. The team lays out the overall plan, attempting to route cooling loops from the server room through the pool shed and into the pool itself, with the pool acting as a massive heat sink. They discuss practical constraints, such as buried lines, the need for a reliable “set and forget” solution, and how to avoid fighting the house’s air conditioning by overheating the server room. Early on, they identify a plan to repurpose in-ground tubes and craft a mixed approach using car radiators, PEX tubing, and various fittings to bridge the gap between the server hardware and the pool loop. The dialogue emphasizes the learning curve of plumbing, tool costs, and the reality that small missteps can cascade into bigger issues, all while maintaining a humorous and improvisational tone. By the end of the segment, the team reveals their intention to test heat transfer performance by stress-testing the CPU and GPU while the external cooling loop runs, and to iteratively improve the setup as leaks and pressure challenges arise.

Questions answered
- What is the primary goal of the pool watercooling project?
- The goal is to use the pool as a massive heat sink to cool a PC, including high-end components like an Intel Core i9-13900K and an RTX 4090, by circulating coolant between the server room and the pool loop.
- What challenges do the builders face during installation?
- They encounter buried line constraints, leaks, the need for proper adapters, and the difficulty of connecting various tubing sizes and fittings while keeping the system leak-free and functional.
- How do they evaluate cooling performance during testing?
- They run a stress test on the CPU and GPU while monitoring temperatures to see if the pool loop reduces temps compared to the rack cooling solution.
- What is the overall mood of the project as it unfolds?
- The mood is a mix of enthusiasm and chaotic experimentation, with humor about the imperfect, makeshift plumbing and the willingness to try multiple approaches to reach a working solution.
