In short: Sony’s PlayStation 5 is one of the largest consoles the company has ever released. The Japanese gaming giant has historically released a thinner version a few years into the system’s life cycle, but one modder didn’t want to wait that long and took matters into his own hands.

Matt from DIY Perks recently dismantled the still scarce PS5 and began to reduce its area. The standard PS5 is 4.1 inches thick, but Matt wants to shrink that down to less than one inch (0.79 inches to be precise). The key to achieving this goal will be to completely upgrade the cooling system and move the power supply.

Much of the PS5’s girth is due to the heatsinks designed to keep various system components from overheating. Once you remove them, you will find that the PS5 motherboard is actually quite thin. Of course, these components still need to be cooled or they will burn out within seconds of turning the system on.

To do this, Matt turned to water cooling. But even off-the-shelf components won’t help here, as they take up too much space for this particular application, so Matt had to build a special 3-layer copper water block to keep everything cool.

His method may seem a little rough, and the end product – even after a quick buff – doesn’t look as polished as you’d expect from a retailer, but the cooling circuit is airtight and waterproof, and that’s all that really matters. . Gaskets and hot melt adhesive were applied to the cooling plate to remove heat from the secondary chips, which also get hot. The SoC received a new liquid metal coating, and an original bracket was used to hold the plate in place.

Several other chips also received spacers for heat dissipation to a separate cover. However, the VRM needed more powerful cooling, so Matt modified the original PS5 heatpipe to connect it to a secondary fluid channel he made in a copper layered water block.

Another hurdle Matt had to face was the power supply. Sony installed the power supply inside the PS5, but if it was done here it would more or less defeat the purpose of the project given its size. Instead, Matt used an external power supply, which is a little less aesthetically pleasing.

Matt chose a computer power supply and mounted it in a long rectangular case that also houses the heatsink and water cooling pump.

The custom cover was made to match the rest of the aesthetic before everything was zipped up and polished. After a bit of a freak out, the system eventually got up and running and was ready for a thermal test to see if it was at least as efficient as a stock PS5. But then there was trouble.

Matt inadvertently blocked the air intake on the radiator, causing the system to overheat and seemingly fail. Luckily, he had a spare PS5 on hand and was able to quickly transplant its innards to get it working again. This time, he added thermal sensors to easily check the temperature in key places, and there were no problems.

PS5’s water-cooled temperatures were much warmer than the standard PS5, but that’s to be expected. Even better, the case measures just 1.9 cm (0.75 inches), which is even thinner than expected.
