We spent quite some time conducting research on insulation when we were designing the original PS5. The basic structure remains the same in the PS5 Pro, but we made some improvements by adding fine grooves where the liquid metal is applied, so that the cooling effect is more stable. When we were doing research for the original PS5, we anticipated that semiconductors would continue to advance and become much denser, so we believed liquid metal technology would become crucial. It turns out we were right, and it was integral when designing the PS5 Pro.
