A CFI-1116 PlayStation 5 suffering from severe overheating has revealed signs of long-term degradation around its liquid metal thermal interface. 4 Reviews ← exclude selected types ← exclude selected tagsAn older PlayStation 5 has developed a severe overheating problem that appears to be linked to degradation around its liquid metal thermal interface. He consequently questioned whether fresh liquid metal should be reapplied to the damaged surface or whether PTM7950 would now be a safer replacement. iFixit notes in its PS5 liquid metal replacement guide that the material can oxidise or become unevenly distributed across the APU and heatsink over time. Over time, oxidised liquid metal may take on a dried or cracked appearance, while overheating and throttling are among the potential symptoms.
