This Guy Built the World’s Quietest DIY PC – Could You?


When you have a high-end PC, you expect it to be noisy. Running the latest processor and graphics card with a massive PSU will cause your fans to make a racket. This is especially true when you’re at max load. Short of placing your PC in another room, it’s nearly impossible to use a powerful CPU silently.

However, one popular YouTube DIYer rose to the challenge. He built a silent cooling mechanism that works to keep his gaming rig's temps in check.

Who Built It

Matthew Perks is the craftsman behind the project. He specializes in creating tech DIY projects. He also recycles old electronics to give them a new lease on life. You can find his work on his channel, DIY Perks.

How It Started

Back in 2020, Matthew created a concept fan. He got the idea for the fan from bellows. Historically, these primitive devices have been used to pump air for a variety of applications.

He built his design using magnets and water pumps to move a giant acrylic sheet. This sheet then pushes the air in and out of the system to provide silent cooling. After four attempts, he finally got the fan working.

He made a rough comparison between his concept and four 140mm (5.5-inch) conventional fans. Both systems had similar air volume output and cooling power. However, his creation worked with negligible noise levels compared to the fans.

One Year Later

After over a year, Matthew got to building the computer he will use his fan with. It runs an AMD Ryzen 9 5950X CPU and a Zotac RTX 3080 GPU, with two 32GB Crucial Ballistix 3600MHz RAM sticks. It’s powered by a passive PSU, ensuring that no fan noise is introduced in his build.

However, as he attempted to install the PC to the fan, he broke his original creation. This necessitated a couple of additional steps in the building process. At first, the issue seemed hopeless. But he eventually saved it through ingenuity and some chemistry.

After all the effort, Matthew created a computer that makes almost no sound. Even when running at full power, you can barely hear the noises his system makes. Now if your laptop has a noisy fan, but you don't want to build something like this, check out some of the things you can do to solve it.

The Result

Temperature record passmark for quietest DIY PC

To test the effectiveness of his creation, Matthew ran Prime95 to stress-test the processor. The AMD Ryzen 9 5950X generates a lot of heat as the program maximizes its power. The hottest temperature recorded was 60°C (140°F) at full load. That’s an excellent result considering his cooling solution is DIY.

He also launched PassMark to benchmark the 3080 video card. The max temperature recorded was 62°C (143.6°F). These are almost the same as the processor, even though GPUs tend to run hotter. Better yet, these results are impressive for a single radiator cooling system!

The First Breathing PC

Although Matthew Perks’s creation is silent and effective, there is one glaring drawback. The system is about eight times larger than your typical full-tower case. Nevertheless, its near-silent operation is perfect for most offices. Furthermore, its unique aesthetic is quite a conversation piece when you have guests.

So what do you think of this cool DIY PC? Do you reckon you could make one yourself? Despite its size, this design could be the future of silent cooling technology. After all, the first computers were room-sized machines with less computing power than your calculator. Who knows what the future holds for breathing computers?
