Story summary

TrashBench turned a countertop ice machine into a liquid-cooling loop for an Nvidia GeForce RTX 3060 GPU.
Adding a thermostat, pump, custom frame and a bowl-submerged evaporator coil lowered load temps to ~21 °C (idle ~6 °C) and cut hotspot from 75 °C to ~34 °C.
Condensation formed, prompting TrashBench to halt the test and label the ice-machine rig a proof-of-concept, not a practical solution because of moisture risk, messy wiring and safety concerns.
