SIE releases PlayStation 5 Pro teardown article, liquid metal-cooled main processor has grooves for improved cooling efficiency
A disassembly article for the PS5 Pro has been published on the official PlayStation blog. Mechanical design leader Shinya Tsuchida and electrical design leader Shinya Hiromitsu provide detailed commentary on the disassembly.

There are three models: the original PS5, the current model, and the PS5 Pro. To improve cooling performance, the PS5 Pro has three slits on the side of the main unit. The design team calls them 'blades.'
The back of the PS5 Pro and the current PS5. The power supply is placed at the bottom on both models, based on the common understanding that 'everyone uses it, so it's better to have it at the bottom when placed vertically,' but the position of the input and output terminals has been slightly adjusted to match the internal circuit design.
The panel is removed and disassembly begins.
To improve cooling performance, the PS5 Pro's fan (left) is larger than the current PS5's fan (right).
The main board is fitted with a metal shield to keep electromagnetic noise below a certain level.
With the metal shield removed, it looks like this. The eight GDDR6 memory chips arranged in a circle on the right side are GDDR6 memory chips, and the ninth memory chip with a red circle to the right of them is DDR5 memory chips. According to Hiromitsu, up until the current PS5, the eight GDDR6 memory chips were used for both 'high-speed processing to run games' and 'low-speed processing to run other OSes,' but with the PS5 Pro, the low-speed processing is left to the DDR5 memory, and the GDDR6 memory is dedicated to high-speed processing.
One of the features of the PS5 is that it uses liquid metal as a thermal conductive material for the main processor. According to Tsuchida, a lot of consideration was given to the initial model, so although the basic structure is the same as the PS5 Pro, improvements have been made, such as adding fine grooves to the part where the liquid metal is applied to improve cooling efficiency.
The number of heatsink pipes has increased to match the increased performance. The silver parts are made of aluminum for better cooling, while the grey parts are made of iron. The two fins that transfer heat from the heat pipes are positioned to provide optimal cooling.
The PS5 Pro can be purchased on Amazon for 113,920 yen including tax.
