PS5 vertical cooling issues
Playstation 5 (PS5) users are reporting cooling issues when the console is used vertically. According to several repairers and technicians, the PS5 uses "liquid metal" as a thermal paste between the CPU and the cooler, but when the console is used upright for an extended period of time, the liquid metal can leak out and cause shorts. -circuits and breakage issues. The cooling of the PS5 would not be optimized to stay upright and this could result in component breakage.
Confirmations from repairers and users
Repairers confirm they've seen an increasing number of consoles leaking liquid metal, and users on Playstation France's Facebook page have also reported similar issues. Liquid metal is highly electrically conductive and can cause short circuits if leaks are not contained. This problem would appear after a few months of vertical operation, according to the repairers.
Improved cooling in the Slim version of the PS5
Cooling should be improved in the future version of the PS5 Slim by using more traditional thermal paste. Sony has not commented on these issues to date. Repairers and technicians advise leaving the console horizontal to avoid problems with liquid metal.
