What happens if you submerge a PC in liquid? If it's water, done. If it's distilled water, maybe 15 minutes. If it's oil, you're pretty much good forever. The coolest thing about this system isn't the oil though, it's the blocks, the GPU block and the CPU block. You might notice there's only one line in. It's coming from the radiator to the block. There's no out. It is actually going directly to the hot component and then spilling out of the water block into the tank. And then there is one out to the radiator that then cools it down and pours it back into the system through those blocks. You might have noticed the bubbles and been a little bit worried about it boiling, but it's probably okay. This particular fluorinate oil has a boiling point of over 100 degrees. This isn't really designed for your PC on your desk. This is an edge compute system. Now, this whole setup without any components and without the oil is going to cost you like $4,000. What won't cost you $4,000 is a Saley eSIM. You can save 15% off now with code LTT.
The video examines the outcome of submerging a PC in various liquids, starting with a quick question about what happens when a computer is placed under liquid. It suggests that water results in an immediate failure, distilled water might allow the system to run for about 15 minutes, and oil can keep the system functioning for an extended period. The presenter highlights the hardware layout, noting the GPU and CPU cooling blocks as focal points, and explains the single inlet line from the radiator that feeds directly into the hot components before the oil exits through the water block into a tank. The flow then returns to the radiator, cooling the oil and rebooting the cycle. The video reassures that bubble formation and apparent boiling are not catastrophic in this setup, given the fluorinated oil used has a boiling point over 100 degrees, while cautioning that this configuration is not a typical desk setup. It also mentions the practical cost of the system, around $4,000 without the liquid and components, and briefly pivots to promote a sponsor discount for Saily eSIM, signaling a sponsored segment typical of the creator’s format. Overall, the video presents edge compute oriented liquid cooling for a compact oil-submerged PC, emphasizing the cleverness of the cooling blocks while signaling real-world limitations and expenses.

Questions answered
- What happens if you submerge a PC in water?
- Water causes almost immediate failure of the system.
- How long might a PC run when submerged in distilled water or oil?
- Distilled water might keep it running for about 15 minutes, while oil can keep it running much longer.
- What is the purpose of the cooling blocks in this setup?
- The cooling blocks harden the focus on hot components like the CPU and GPU, directing cooled oil through them to manage heat.
