It is the first time that Sony provides details about the guts of the PlayStation 5. In a video, the manufacturer shows that users can detach the side panels themselves without having to remove screws. Under one of the panels is a space where a PCIe 4.0 SSD of the M.2 format can be installed. Sony has previously said that users can expand the storage with NVMe SSDs, but they must meet certain speed requirements. Details have not yet been disclosed.
Removing the panels also exposes the console fan. Sony uses one 120mm fan, which is 45mm thick and designed to draw in air from both sides. The console also has notches where dust is collected, according to Sony console owners can remove the dust by vacuuming those holes.
To further open the console and access the motherboard, you will need to remove stickers and screws. This will invalidate the warranty. Sony shows that the Blu-ray drive is equipped with a metal cover and damping material, which is to prevent vibrations.
The soc is soldered to the motherboard and it is provided with liquid metal as thermal paste. Sony says it has worked for two years on applying that material. On top of the motherboard is a large heatsink with heat pipes, which cools the soc and the memory chips as well as the ssd. The SSD consists of a controller and separate memory chips, which are also soldered to the motherboard. Finally, Sony shows the power supply. That’s a 350W one built into the case.
Liquid metal thermal grease has long been used in PCs by overclockers and is offered by various manufacturers. As far as is known, it has not been used before in consoles. Their use involves risks because ingredients of liquid metal thermal paste can attack light metals such as aluminum and certain alloys. As long as the material only comes into contact with the heatspreader and heatsink, this will not cause any problems. Tom’s Hardware conducted a test with 85 different types of thermal grease. The liquid metal variants came out best in that test.
