Sony has released the official PlayStation 5 disassembly video.
It's a maintenance procedure as far as the user can go, as well as a full view of the giant cooling fan, heat sink, and thermal interface material made of liquid metal material.
The PlayStation 5 is much larger than the current PS4, and this video clearly shows that the reason for this is the massive cooling system.
We often see the association of a large cooling system with the idea that it must be so large and noisy, which means it must generate a lot of heat, but at least in terms of thermal design, large is always justified.
It is no different for any device that operates with the same power-efficient processor, which consumes the same amount of power as the performance and always results in heat that needs to be released to the outside world in some way.
Liquid metal is used for the thermal interface material (TIM) that effectively transfers heat from the processor to the massive heat sink.
The larger the diameter of the cooling fan, the more it can deliver the same amount of airflow at lower speeds, which means less noise to your ears and better cooling (Of course, there are numerous factors in addition to diameters, such as the type of fan, the shape of the wings, the motor, the overall airflow design and acoustic design of the chassis, etc.)
The PS5's cooling fan is 120mm in diameter and 45mm thick, double-sided intake. It sucks air in from the front and releases it through the exhaust port on the back.
A slot for storage expansion is located near the fan, which is capped by a white cover. It has a PCIe 4.0 NVMe connected M.2 interface, which allows you to use commercial M.2 SSDs that have been verified by Sony to meet speed and shape standards.
What's also interesting is that there are two dust catchers in two locations that make it easy for users to clean up accumulated dust.
Even if the cooling mechanism and fans are excellent, we are concerned that game consoles, which tend to be placed close to the floor, will absorb and accumulate dust over the years, leading to reduced efficiency and noise. With a limited range that users can disassemble, it's great news that the design has been well thought out to prevent dust.
