A YouTube has developed a submersible PC, using state-of-the-art hardware, including a GPU RTX 4090 and an Intel processor Raptor Lake.
The idea is simple, if the PC is submerged in cold water, the components will have a better heat dissipation. In fact, several technology companies have been experimenting with possible data centers, which would work submerged in the sea, also to take advantage of the benefits of cold water for cooling the components.
Previously, the Youtuber surprised everyone by creating a PS5 with liquid coolingwhich had a thickness of only 2 cm.
Building a Submersible PC
This proposal is not only impressive from the visual point of view and for the fact that the pc can work underwater, but also promises to provide quite good cooling. However, it is important to note that this work is quite complex, since everything has been designed from scratch. A conventional PC case is not suitable for this type of invention, so it has been necessary to put the hardware in a kind of acrylic tube.
Arms and overboard
In this case, the youtuber has incorporated copper tubes that extend out of the cylinder and they are connected with plates in the upper and lower area, thus sealing the cylindrical tube to prevent the entry of water. All that enclosed hardware generates a noticeable amount of heat, since the chosen GPU is an RTX 4090 with an i9-13900K processor. To improve the refrigeration I use a system of custom water cooler for both CPU and VGA.
Once these stages are completed, which include the installation of the metal pipes, the water cooler and be sure there will be no water seepageNow it’s time for the tests. To do this, he placed the PC in a pond located outside his house, where it was possible to observe how the upper part floated while the rest remained submerged under water. The tests were a resounding success, with the coolant temperature barely rising a couple of degrees under load. This allowed the CPU to never go above 60 degrees Celsius and the RTX 4090 GPU to stay below 40 degrees.
Let’s be honest, the results exceeded expectations, and the creator assured that even with continuous use, the temperature of the pond will not be significantly affected.
