Earlier this year, reports began circulating that the PS5 would have an "exceptionally expensive" cooling system, and the recent details that Sony revealed about the console's hardware certainly matched this information and the The main reason is the cost, said Otori when asked why Sony decided to use a liquid metal TIM on the PS5. “The standard for thermal design is to spend money near the heat source. As an analogy to the overall thermal design, lets say you have a system cooling structure that costs 10 yen for a TIM and 1000 yen for a heatsink. If you switch to a 100 yen TIM here, you can get the same cooling effect, even if you use a 500 yen heatsink. In other words, the total cost can be reduced.
Liquid metal was chosen to reduce the total cost of the PS5 cooling system

“Even after overcoming the difficulty of handling and adopting the manufacturing process, the PS5 has finally managed to adopt liquid metal, which should have a big effect.”
Otori spoke more about the difficulties mentioned also in the manufacturing process. Liquid metal TIMs generally go hand in hand with certain problems and, according to Otori, Sony spent two years creating solutions to these problems.
I always wanted to use liquid metal, he said. “However, as the liquid metal is conductive, if it leaks to the side of the substrate, it will short-circuit. Above all, it is highly corrosive to aluminum used in parts such as heat sinks. For the handling of these materials, it is necessary to take measures also for the manufacture of the equipment. It took us more than two years to prepare well to solve these problems. ”
Speaking in the same interview, Otori also confirmed that Sony will continue to improve and optimize the PS5 cooler after the consoles launch with [url=https://www.gamevicio.com/noticias/2020/10/sony-pode-controlar-dynamically-the-speed-of-the-fans-of-the-playstation-5-by-means-of-updates/] firmware updates "> large size of the console ). Likewise, they made cost-based decisions in other areas of the cooling system as well, as Yasuhiro Otori, head of the PS5 mechanical and thermal design team, explained in a recent interview to [url=https://www.4gamer.net/games/990/G999027/20201016035/] 4Gamer "> large size of the console "> suggested that the investment will be worth it.
Sony recently talked about how wanting to cut costs was one of the reasons for using a single large fan on the PS5 instead of two (which resulted in the [url=https://www.gamevicio.com/noticias/2020/10/the-huge-sink-of-the-playstation-5-and-the-reason-of-the-console-being-so-gigantic/] large size of the console ).

The liquid metal cooling of the PS5, for example, was chosen for the console to reduce the overall cost of the cooling system. Although an isolated liquid metal thermal interface (TIM) material is more expensive, it is effective enough to allow Sony to choose cheaper components elsewhere.
