We spent fairly a while conducting analysis on insulation after we had been designing the unique PS5. The essential construction stays the identical within the PS5 Professional, however we made some enhancements by including nice grooves the place the liquid steel is utilized, in order that the cooling impact is extra secure. Once we had been doing analysis for the unique PS5, we anticipated that semiconductors would proceed to advance and change into a lot denser, so we believed liquid steel expertise would change into essential. It seems we had been proper, and it was integral when designing the PS5 Professional.
