RTX 3080 Cooled by a Magnetic Device Pulled Straight From a Forge
A Youtuber has built an efficient computer cooled without the use of fans. Instead, he used something like a magnetically driven bellows. The result is marvelous.
- Youtuber Matthew Perks has built a magnetically breathing PC - quiet, cool, and powerful;
- Powerful in the literal sense, too.
Powerful PCs need equally powerful cooling. The most popular systems use fans, but they can be quite noisy. Passive cooling, on the other hand, while silent, is difficult to implement with powerful components like the GeForce RTX 3080. Youtuber Matthew Perks of the DIY Perks channel came up with the idea of using a magnetically driven bellows to make his PC both quiet and cool. It also takes up a lot of space, but this is just a prototype for now.
The bottom part of this huge case (made mostly of MDF) contains the biggest element, which is a chamber with a movable surface suspended on rails. It is driven by a magnet, placed in an acrylic tube and moved by water flow. A kind of "diaphragm" is connected to the driving rail through a magnetic field. Therefore its movement is very smooth (magnetism provides compensation of inertia). Magnets at the ends of the tube further enhance this process.
The piston movement of the magnetic bellows through the side openings generates airflow, which is directed through flap valves and takes the heat away from Alphacool's water cooler. The rest of the system is more conventional - the liquid flows through both the GPU and the CPU to cool them down. This high-end PC consists of a 16-core AMD Ryzen 9 5950X processor, Zotac's GeForce RTX 3080, and 64GB of RAM from Crucial mounted on an ASRock motherboard.
Despite the top-of-the-line components, the PC remains cool. The GPU reached a temperature of only 62 degrees Celsius during testing. So efficient is the prototype cooling while being very quiet. Only the banging of the air valve flaps is audible, but the developer will be able to solve this problem. Only this size... You'd need a lot of space for such a computer.
