Block, Shmock — Just Pump Water Over The Chip

A hardware experimenter bypassed traditional water blocks entirely by epoxying 3D-printed pipe fittings directly onto bare GPU and CPU dies for direct liquid cooling. The GPU saw better thermal performance than a professional water-cooling setup, but the CPU results were poor and the experiment caused leaks that nearly damaged the hardware. The difference in results between CPU and GPU raises interesting questions about chip die exposure and heat transfer.
