This is the world’s thinnest and quietest PS5

By inserting the PlayStation 5 motherboard into a handmade copper water block housing connected to a hidden water cooling system, a hacker has turned the Sony console into a work of art … which hides a troublesome secret.

PlayStation 5 is big and bulky: that’s a fact. If one of its pages stays thinner than Microsoft’s Xbox series, it’s recording an impressive volume. Volume is needed to quietly cool its CPUs and GPUs, the very large size of the fan and the cooling plate, thus avoiding the hum of previous generation consoles.

Hacker Matt from the DIY Perks YouTube channel has decided to slim down his console by removing … absolutely everything. Plastic cabin, metal cage, cooling plates, but also the power supply has been removed (and partially remotely controlled, read below). that mud (as they are called in Anglo-Saxon jargon) thus restored the motherboard and designed a new case only 2 cm high. For the purpose of relying on the principle of water cooling.

Just buying copper costs a fortune.

The adventure told in a 30-minute video is not easy and requires time, tools and materials … not necessarily given. Just the copper plates that have been cut and soldered together almost cost the price of a PS5. In addition, a block of water, which the handyman has cut to the nearest millimeter, but also a pumping system and an external cooling system, to which he has added a power supply, also external.

The console is cooled by a stream of water (water cooling)

In addition to the skills and equipment, the two shortcomings of this “PS5 Slim” are therefore the total price of the solution, which fortunately must triple the starting price. But also the overall size: If the electronic part of the console has been reduced, considering the total amount of visible and invisible elements, we realize that Sony’s engineers have worked well.

The total size of the water-cooled solution is larger than the original console.

This does not detract from the mastery of Matt, who should not only overcome startup problems, heating up, etc. to create a console with a unique look. But he also managed to cool his console logically much better than Sony. Its water cooling system is actually much more efficient than the classic air cooling on the original console.

Water cooling lowers the temperature well below a conventional PS5.

This ingenious handyman performance highlights the challenges facing Sony’s mechanical and thermal engineers working on the PS5 Slim, a highly anticipated development of the console that is still criticized for its bulk. How to reduce its dimensions? Certainly not with overpriced copper and a water cooler assembly that is anything but suitable for consumer use. On paper, in addition to new metal alloys, some airflow tricks, etc. Sony’s main ally in this regard would be the fine engraving of the chips.

The “brain” of the PS5 is engraved in 7 nm by TSMC and is an all-in-one chip (SoC) that integrates both 8 Zen 2 CPU cores that can go up to 3.5 GHz and 36 Compute Units (CU ) at 2.23 GHz. However, AMD and its partner TSMC have mastered the transition from 7 nm to 5 nm chips very well. This track seems likely: TSMC explained in 2020 that the production launch yield at its 5 nm was already better than the launch of 7 nm. Almost two years later, 5nm fabs are running at full speed, 4nm has taken over at the very high end, 3nm is coming in late 2022 / early 2023 and 2nm is scheduled for 2025.

If Sony manages its launch timing well (end of 2022? During 2023?) And has succeeded in optimizing its production costs – which is often the main reason for the arrival of “bis” or “slim” consoles – then a passage at 5 nm is possible. A miniaturization that would reduce energy consumption by 20%. Not enough to reach a 2cm high PS5 Slim, but more than enough to make the dissipator and cabin lose weight.
