Reports from international repair centers indicate that Sony’s liquid-metal cooling solution for the PlayStation 5 is showing long-term reliability challenges. The thermal interface material, chosen for its high conductivity and ability to move heat efficiently from the processor to the cooling assembly, appears to degrade over extended use. As this material ages, it can migrate beyond its containment frame, creating electrical and thermal problems that can eventually disable the system.
One recent case involving the PS5 Slim (model CFI-2016) highlights how early these issues can appear. The console in question had been used for less than eighteen months and arrived with unstable operation linked directly to liquid-metal leakage. According to the technician who serviced the device, the failure could not be traced to improper handling or poor placement. Instead, the liquid-metal layer showed visible breakdown caused by repeated heat cycling, which slowly weakened the coating and allowed the material to escape its designated zone.
Independent repair specialist modyfikatorcasper has seen enough similar cases to consider the problem inherent to the cooling design. He argues that the compound’s long-term behavior under thermal stress poses a risk for all revisions of the PS5. Although the claim that every console will eventually need service is difficult to substantiate, the number of observed failures suggests that the issue is not confined to isolated units.
Additional industry commentary reinforces this trend. Matthew Cassels, founder of Alderon Games, has noted a substantial increase in user-reported PS5 failures associated with liquid-metal instability. Symptoms range from inconsistent performance to non-functional systems, and most of the confirmed cases involve early PS5 models that have spent several years in service. Their longer operational lifespan has exposed them to more temperature fluctuations, increasing the likelihood of material degradation.
Sony has implemented several structural changes in newer hardware revisions, including the PS5 Pro and updated base models. These updates aim to stabilize the liquid-metal interface, reinforce containment mechanisms, and reduce the stresses that lead to wear over time. However, these changes have only been in the market for a short period. Technicians will need significantly more field data before determining whether the updated cooling solution meaningfully reduces long-term failure rates.
The widespread attention this issue is receiving underscores the complexity of deploying liquid-metal materials in consumer electronics. While the performance benefits are substantial, maintaining long-term stability requires precise engineering and tight manufacturing controls. The PS5’s experience illustrates both the advantages and risks of such an approach, and it remains to be seen whether subsequent revisions fully resolve the problem.
