The problem with the liquid cooling solution: if the Sony console is placed vertically, the material can theoretically leak, which can cause it to spread on the circuit board.
Therefore, in addition to short circuits, heat from the APU is no longer properly transferred to the heatsink. In the worst case, the PS5 becomes completely unusable.
If you want to be on the safe side, it’s best to place your PlayStation horizontally. Incidentally, user reports show that the problem occurs with both the purely digital PS5 and the PS5 with a drive.
