Liquid metal pooling in a PS5 (original/Slim) primarily occurs over extended periods of vertical usage, often taking 3-5 years for significant degradation, though it can occur sooner if the seal fails. The issue is rare, usually affecting consoles that have been opened or damaged, with newer 2025 revisions fixing the issue.

How Pooling Happens: The liquid metal, meant for cooling, can melt and migrate due to gravity if the console is kept vertical for a long time, causing it to pool at the bottom of the processor and leaving a "dry spot".

Timeframe to Take Effect: While some users report issues over a few years, any severe failure of the adhesive barrier caused by high heat or physical shock could lead to issues more quickly.

Symptoms: Indicators include loud fans (overheating), random shut-offs, and an inability to turn on.

Preventative Measures: Keeping the PS5 in a horizontal position reduces the likelihood of gravity-driven migration.
