The PS5 Pro was launched in late 2024, but Sony had not yet offered a home teardown of its console, leaving the field open to specialized sites like iFixit. This has now been done with a long post blog showing the innards of the beast.
It includes information already revealed by others, such as the integration of a new DDR5 memory chip for managing background tasks and the new redesigned motherboard.
But the most interesting elements shown by Sony concern the cooling. Two points in particular catch the eye: the new liquid metal integration and a new fan.
Improved Liquid Metal Integration
Regarding liquid metal, let's briefly explain what it is before going any further. Cooling a chip involves a whole bunch of devices: copper pipes, radiators, fans, etc. But closer to the chip, it is often necessary to add a thin layer of thermal paste to help transmit heat quickly from the chip to the rest of the cooling system.
When the PS5 was released, Sony decided to apply a thermal paste like no other to its chip: liquid metal. Its heat transmission power is 4 to 6 times greater than that of a conventional thermal paste, which explains why Sony spent two years racking its brains to develop its own tooling.
Except that, in 2023, a controversy suddenly broke out: the PS5 should not be left upright, at the risk of the famous liquid metal dripping onto the other components. Several technicians confirmed the problem at the time, but in hindsight, it seems that only a small series of consoles were affected.
So back to the PS5 Pro and its disassembly. While Sony has not commented on the controversy, it has nevertheless slipped in a form of response: "We adopted it after carrying out various tests to ensure its safety.".
The article does, however, confirm that the arrangement of the liquid metal in the PS5 Pro has been reworked.
A new fan, a more powerful power supply, and the Wi-Fi 7 chip
That's the big stuff. Sony also took the opportunity to show off some slightly more secondary, but equally interesting, elements.
We'll start with the new fan. This one is both larger and more efficient, the company explains.
There's also a new power supply, which you can see below. This produces an additional 48W to power the more demanding components of the machine.
Finally, it's not very visual, but at the bottom right of the motherboard, a small silver rectangle stands out. This is the new Wi-Fi 7 module, placed in exactly the same place as the Wi-Fi 6 module of the basic and Slim PS5s.
