I Can't Believe This Worked!!! - Concrete Cooled PC (April Fools 2019)

The video centers on a bold, experimental cooling idea for a high-end gaming PC: using concrete as part of a liquid cooling loop. The hosts recount a viewer suggestion to try chilled concrete as a coolant after testing other exotic liquids, and they assemble a capable rig to put the concept to the test. They choose a modern gaming machine with a strong CPU and GPU, and they repurpose an older case to house the setup. After mixing concrete and water, they attempt to pump the slurry through a loop designed to remove heat from the processor. Early baseline tests with water show a clear improvement when the concrete is introduced, and the team carefully monitors CPU and system temperatures as the concrete loop stabilizes. The moment of truth arrives when the pump runs, the loop fills, and the system demonstrates a notable drop in CPU temperatures, validating at least the feasibility of the idea under controlled conditions. They acknowledge potential downsides, such as reliability and power considerations, but emphasize the recorded temperature gains as a strong proof of concept. The segment closes with comedic relief and a sponsor message, reaffirming the playful yet data-driven spirit of the experiment while inviting viewers to discuss outcomes on the forum and explore related products and gear.
