Infinity Edge, Submerged Cooled Build: 12900KS, 128GB DDR5, 2x 3090Ti's, 2x4TB NVMe's

Infinity edge, submerged cooled build anyone?

This is a prototype build for a very creative client that wanted to push the idea of what a computer could be. Specifically, what a waterfall cooled PC could be. He contacted me after seeing my Zen Tower build. At first, this was a build utilizing a Z-Tower. After some issues with a welder, we scrapped that and created our own case which became the foundation for what you see here. We went with the infinity edge, submerged design that you see here with the highest end components at the time of building. This computer is an installation piece designed to be installed on a desk. The cooling unit and power supply were to be hidden below the desk in a compartment. The case needed to be able to fit inside a Pelican 1650 case for travel. We were constrained by the width, depth, and height. Ultimately we were able to keep it at 4 inches of height. It is by far one of the most difficult projects I've been a part of. It was the first time I utilized my CNC. I learned an insane amount along the way and was very rewarding. This project was the culmination of 8 months of discussion. The final build took over 100 hours to create.

As for performance, unfortunately it's horrendous haha. It will keep from thermal throttling and everything boosts to their max clocks. However, they do so in the mid 90's. For this build, there is only one central location for the fluid to flow back into the basin and sits below the motherboard. This creates dead-zones near the components. For better cooling, we need to force fluid directly over the main components. For the second prototype, we will need multiple points of entry to more evenly, and more quickly, evacuate the hot fluid from the components. You can clearly feel hot spots in the build, even though coolant never breaches 35C in a 25C environment. Fluid was also flowing at around 5.1 liters per second, courtesy of two D5's. We may also need to force more flow with a submersible pump.

A lot learned, and a lot to improve in the next revision.
