Repair Service Attributes Overheating Issues to Original PS5 Design Flaw
Electronics repair shop TronicsFix warned about PS5 overheating issues several years ago, and those findings have now been confirmed.
According to TronicsFix, the liquid metal in early PS5 models can shift away from the APU cooling system over time, especially if the console is kept in a vertical position for long periods. Inadequate power supply ventilation is cited as another issue.
In a new video, TronicsFix tore down two PS5 consoles that had been brought in with overheating complaints. In both cases, the liquid metal had indeed shifted, and reapplying it resolved the issue, stopping the consoles from displaying overheating warnings in certain games.
First, try to keep your PS5 clean. Second, even on the PS5 Slim, the liquid metal issue remains a serious concern. The main design flaw of the PS5 is the liquid metal running off the APU. And third, the ventilation is inadequate. In my opinion, it is not sufficient for the PS5 power supply. Those vent holes are simply too small and poorly designed.
Salem Techsperts reached similar conclusions. Sony only fixed the design flaw in the PS5 CFI-2100 version released in September 2025. It features a modified cooling contact surface with grooves, similar to the PS5 Pro, which prevents the liquid metal from shifting.
