A PS5 has dimensions of 390 x 260 x 104 mm, or 92 mm in the digital version that does not accept discs. It is very big. Doesn't fit upright in an Ikea Kallax. This is why a Slim model is expected to arrive in a few years, but a user did not want to wait for it.
Matt from DIY Perks has created his home version of the PlayStation 5 Slim. To perfect it, it has added a custom liquid cooling circuit to improve thermal performance compared to that of the stock console.
A PS5 can be only 2 cm thick
The PlayStation 5 Digital Edition is 92mm thick, and Matt's ambitious goal was to reduce the thickness of the console to 20mm. That's a 78% reduction. That means Matt must get rid of the case, heatsinks, and more. In his quest to make a homemade PS5 SLim, the only key component he was able to salvage from the original PlayStation 5 was the motherboard.
Matt created a full-cap water block for the motherboard, flash storage, power circuitry, VRM, and custom heatsinks for the other components, like the GDDR6 chips. He also made a copper box for the project. He acknowledges that the copper plates alone already cost more than the PlayStation 5. But It is not a project designed to be done in series, and it is only to experiment and give content to your channel.
The original PlayStation 5 power supply supplies 31A at 12V, so a suitable alternative should have been easy to find. It was replaced by an HP DP5-750RB A power supply with a capacity of 750W. It offers up to 62,5A at 12V, which is enough to power the cosnola and Matt's custom water cooling circuit.
Then, built an external aluminum case to house the power supply and water cooling components with one of the slim 7x40 radiators from Alphacool along with seven small Noctua NF-A4x20 fans for heat dissipation. It also used an unspecified reservoir and pump.
Needless to say, his first one ended badly, as the console froze during his tests and refused to turn on. He got a second PlayStation 5 and managed to finish the project.
Much more than make it fine
As well as being slimmer than the original PS5, this homemade slim version was aimed at lower operating temperatures. That's where the custom water cooling loop comes in. Added three temperature probes to measure AMD SoC, memory, and VRM.
Testing Horizon Forbidden West for several hours, it registered 46 degrees Celsius on the SoC. Since the temperature probe is not inside the SoC, he estimated the temperature to be around 65 degrees Celsius. The memory recorded temperatures of 52 degrees Celsius, while the VRM only got as hot as 44 degrees Celsius. Comparing their results to the Gamers Nexus thermal tests for the vanilla PS5, Gamers Nexus recorded 75 degrees Celsius on the SoC, 95 degrees Celsius on the memory, and 71 degrees Celsius on the VRM. Compared, Matt's PS5 Slim recorded 13% cooler temperatures everywhere.
