The world is getting warmer every year due to worsening climate change. If you live in certain parts of the world affected by El Nino, you're likely seeing your devices overheat right now if you live without an air conditioner. So, what if you could devise a solution to keep your computer cool regardless of ambient temps? That's precisely what YouTuber TrashBench did by altering a standard countertop ice machine to work as a GPU cooler.

We've covered TrashBench's escapades before, such as that time they used car antifreeze to cool a GPU, or when they put the entire test bench inside a freezer, or even the video where they dunked the entire graphics card into transmission fluid. In this case, the idea of using an ice machine actually came from fellow modder MrYeester who already cooled a CPU with a smaller one — now, it was time to take the concept to another level.

The YouTuber began by disassembling an RTX 3060; he removed the stock cooler and mounted a custom retention frame over the die to fit the liquid-cooling tubes. He then put a submersible water pump inside the ice machine and simply filled it up with water to create the loop. The hot water from the GPU falls into the bucket where it should be cooled before being looped back to the card.

Just for the sake of it, the modder tested the GPU without turning the ice machine on and it actually achieved around 44°C in benchmarks. The temperature wouldn't stabilize because nothing is cooling the water, so he turns on the machine, and the temps actually fall by more than 10 degrees. However, the GPU is heating up faster than the water can cool it down because the ice machine is on a fixed clock cycle.

Basically, the compressor only runs for a few seconds at a time before turning back off once the ice has been discharged into the water. This interval is controlled by a thermostat that can't be adjusted, so it was time to rip it out entirely and replace it with another one. TrashBench luckily had another one that will bypass the internal logic and force the compressor to stay on perpetually.

But just running the compressor longer doesn't result in better cooling. The evaporator coils are responsible for facilitating the heat exchange and they weren't submerged enough in the water. To fix this, the YouTuber simply put a small plastic bowl under the coils to the point they were completely drowned. Hot water coming from the GPU will now hit the evaporator, which helps improve the cooling efficiency, while the new thermostat ensures the compressor doesn't turn off.

Once everything was ready, TrashBench ran the numbers once again and the results were a success, to say the least. Before the modding began, the RTX 3060 was reaching around 60°C in Cyberpunk 2077. Now, it was casually chilling at 22-23°C, and it was stable. The GPU hot spot was sitting at 75°C before, while the modified ice machine brought it all the way down to just 34°C.

There were some leaks in the middle that the YouTuber dealt with, and the entire modding process was a bit too involved for a quick and fun experiment. Not to mention, messing with the internal componentry of an electrical device that's carrying water isn't exactly the safest thing to do. Still, the results speak for themselves, and we can only wonder how far you could take this RTX 3060 now with extreme overclocking.
