This is more of a PSA if your PS5 is experiencing any quirks.
TL;DW: the liquid metal on the PS5 can oxidize creating areas of the APU that don't get full cooling, this can lead to overheating/artifacting/less than optimal performance. This person has encountered multiple PS5s with oxidized liquid metal spots. CLEAN OUT your PS5, they weren't joking about the vacuuming it out periodically. He also recommends leaving it horizontal.
