This solution is an impressive feat of engineering, but don’t think that means your PS5 will never get warm.

So this means PS5 will run as cool as an ice cube, right? Not really And that likely speaks to advances in the durability of the alloy. Asus is shipping its first laptop with a liquid-metal TIM this year. Sony also isn’t the only company doing this. This is likely key to dealing with the conductivity and shifting issues. “Various conceivable tests have been conducted during its adoption process.”Įarlier this year, Sony patented an insulating sheet that basically acts as a corral for the liquid metal. “We have spent over two years preparing the adoption of this liquid metal cooling mechanism,” Ootori said. This led to situations where you would have to reapply the TIM regularly.īut Sony has obviously solved these engineering complications. Finally, previous liquid metal alloys used for this application weren’t very durable. Liquid metal also moves around a lot, which makes it difficult to ship to consumers. The risk is that it could get on other parts in a system and cause them to short out or malfunction. It’s difficult to apply because it’s electronically conductive. If liquid metal is a better thermal-interface material than paste, then why would you ever use the latter over the former? Well, liquid metal is a challenging substance to work with. Why doesn’t Sony or Microsoft always use liquid metal? “The PS5 utilizes liquid metal as the TIM to ensure long-term, stable, high-cooling performance,” said Ootori. That need led Sony to go with liquid metal. “This led to a very high thermal density in the silicon die, which required us to significantly increase the performance of the thermal conductor, also known as the TIM, that sits between the SoC and the heatsink.” “The PS5’s SoC is a small die running at a very high clock rate,” Ootori said. During his teardown of the PS5, Sony engineering vice president Yasuhiro Ootori explained why. Typically, systems use a paste-style TIM, but that isn’t good enough for the PS5. And that’s the job of the thermal interface material (TIM). But to get the most out of that routing, you want to ensure as strong a connection between the chip and the heatsink as possible. The important part of this system is called the heatsink. Cooling usually works by putting a conductive material onto the chip to route the heat outside of the system.
