Custom Liquid Cooling for LESS $ than an AIO Cooler!?

In this video, the host claims to build a custom liquid cooling loop for a CPU at a cost far below typical AIO coolers, and immediately starts by outlining the budget mindset and what parts are being sourced on a tight budget. He walks through the exact components purchased from Amazon, noting mismatches between product pictures and real parts, and he explains the constraints of a low price point, including a nonstandard radiator, pump, and a copper CPU block. Throughout the build, the host emphasizes the hacky nature of the setup, including improvised mounting, makeshift connections, and a focus on reusing existing case fans to keep expenses down. The video also shows the planning steps for bleeding air from the loop and arranging tubing in a way that forces bubbles to travel toward the inlet, highlighting how placement matters when using a lower-quality pump. In the test results, he runs a baseline with an existing air cooler for comparison, then measures a claimed temperature improvement after stressing the CPU, and concludes by noting a notable temperature drop and calling out the project’s playful, deliberately imperfect nature. The outro ties back to Black Friday deals and other Linus Tech Tips content, inviting viewers to check sponsors and related videos while reflecting on the experiment as a fun, educational hack rather than a production-grade solution.
