As the PlayStation 5 console enters its sixth year of product lifecycle, professional repairers have recently pointed out that the liquid metal materials used for critical heat dissipation inside all PS5 models may experience performance degradation over time and ultimately require professional maintenance. This potential issue has raised concerns in the player community about the long-term reliability of the console.
This warning originated from a case study posted on social media by Modyfikatorcasper, a modifier and maintenance technician. He showcased a PS5 Slim (model CFI-2016) that has been in use for less than a year and a half, and its liquid metal located between the acceleration processor unit and the cooling system has undergone significant degradation. The material dries up, oxidizes, and solidifies into blocks, completely losing the key physical properties of efficiently conducting chip heat to the heat sink.
Modyfikatorcasper explicitly stated that this issue affects all PS5 models and is not an isolated case. He believes that this is even one of the reasons that prompted Sony to adopt deeper groove heat sinks in the PS5 Pro design to better prevent liquid metal leakage or drying up. He also confirmed that Sony has made similar upgrades and improvements to the cooling system by launching revised models such as CFI-2100, CFI-2200, and CFI-2116. He emphasized that the horizontal or vertical placement of the host is not related to the occurrence of this problem, and the performance degradation of liquid metal will still occur.
The placement posture of the host cannot prevent the degradation of liquid metal. This fault even affects the latest models that have only been used for one year. The main reason is the quality of the coating process and the material degradation that occurs over time and temperature, “he concluded.” All PS5 hosts – regardless of the model – will ultimately require professional maintenance! ”
When asked if this was just a few defective products, Modyfikatorcasper responded based on his repair experience that he had dealt with multiple PS5s sent for repair due to overheating issues. However, it should be pointed out that Sony has not yet made any official statement regarding the possibility of this issue being widespread in the old PS5. Some analyses also suggest that there may be a certain degree of “confirmation bias” in the perspective of maintenance technicians – due to their frequent exposure to faulty equipment in their daily work, it may amplify their perception of the universality of the problem.
If this issue is confirmed in a wider range of PS5 stock devices, due to internal material aging, devices within the warranty period are likely to be covered by Sony’s official warranty policy. For out of warranty hosts, users may face the option of paid maintenance. The development of this matter requires further response and explanation from Sony officials.
