Sony may replace the liquid metal cooling system used in the PlayStation 5 with a vapor based design for the PlayStation 6, according to a recently published patent.
The proposed system uses a liquid such as water inside a sealed cooling assembly, along with several tapered heat pipes that regulate circulation. Heat from the console’s main processor would cause the liquid to evaporate, move through the cooling structure, and then condense as it releases heat.
This approach could give Sony a more conventional and easier to manufacture alternative to liquid metal. It may also reduce concerns about cooling performance when the console is placed vertically.
The patent does not confirm the final PlayStation 6 design. Companies regularly protect technical ideas that never appear in commercial products. However, the filing suggests Sony is evaluating different ways to manage the heat generated by its next generation console.
The proposed system uses evaporation to move heat away from the processor
A vapor chamber transfers heat by circulating liquid and vapor inside a sealed structure.
When the processor becomes hot, the liquid near the heat source evaporates. The vapor then moves toward cooler areas, where it condenses and transfers its heat into the surrounding cooling hardware. The liquid returns to the original area and repeats the process.
Tapered heat pipes could help control this circulation and maintain cooling performance regardless of the console’s position.
| Cooling detail | Proposed PlayStation 6 approach |
|---|---|
| Main cooling method | Vapor based heat transfer |
| Working fluid | Potentially water or a similar liquid |
| Heat movement | Evaporation and condensation |
| Supporting hardware | Multiple tapered heat pipes |
| Console orientation | Designed to work vertically or horizontally |
| Manufacturing benefit | Modular installation |
| Final use in PS6 | Not confirmed |
The system would still require a heatsink, airflow, and one or more fans to move heat out of the console. The vapor chamber would primarily improve how heat travels from the processor to those larger cooling components.
Vapor chambers could simplify console manufacturing
Sony used liquid metal between the PlayStation 5 processor and its heatsink because it transfers heat more efficiently than ordinary thermal paste.
The material also creates manufacturing challenges. Liquid metal is electrically conductive, so it must be applied carefully and contained within a protected area. A spill during assembly or repair can damage nearby components.
A vapor chamber is a self contained module. It can be installed over the processor using manufacturing methods similar to those already used for conventional heatsinks.
This could reduce the number of delicate steps on the production line and lower the risk of damage from incorrect thermal material application.
Simpler assembly may also help Sony control manufacturing costs. Cooling systems become more expensive as processor power and heat output increase, so reducing complexity could be important for a console expected to use advanced hardware.
Reports of PlayStation 5 liquid metal failures remain disputed
The PlayStation 5 cooling design has faced criticism because of reports claiming that liquid metal can move or leak when the console is used vertically.
Some damaged systems have shown liquid metal outside the intended contact area, leading to overheating or component failure. However, these cases do not prove that every vertically positioned PlayStation 5 faces the same risk.
Damage can also be influenced by previous repairs, physical impact, incorrect disassembly, manufacturing defects, or deterioration of the protective seal around the processor.
Sony has continued selling the PlayStation 5 with liquid metal cooling across several hardware revisions. The company has not issued a broad warning telling owners to avoid using the console vertically.
The patent therefore should not be treated as confirmation that Sony considers the current system fundamentally defective. It may simply show that the company is testing a solution better suited to future hardware.
PlayStation 6 hardware may require a different cooling strategy
A next generation console will likely include a faster processor and graphics architecture than the PlayStation 5. Even if newer manufacturing technology improves efficiency, higher performance can still create significant heat.
Sony will need to balance several factors when designing the cooling system.
The console must remain quiet enough for living room use, fit within a practical enclosure, and operate reliably during long gaming sessions. It must also be affordable to manufacture at a large scale.
A vapor chamber could spread heat more evenly across the cooling assembly. This may allow Sony to use a thinner or more efficient heatsink while avoiding concentrated hot spots around the processor.
The final design will depend on the power target of the console, the size of its processor, expected manufacturing costs, and the amount of airflow available inside the enclosure.
The patent does not confirm PlayStation 6 specifications or pricing
The filing provides an idea of what Sony is researching, but it does not reveal the final appearance, power consumption, release date, or price of the PlayStation 6.
Claims that the next console could cost $1,000 or more also remain speculative. Component prices, memory capacity, manufacturing agreements, and Sony’s broader hardware strategy will determine the eventual price.
Sony could use the patented cooling design in a PlayStation console, a development system, another electronic product, or not use it at all.
The more reliable takeaway is that the company is exploring cooling methods that avoid direct reliance on liquid metal while supporting powerful hardware in different orientations.
A vapor chamber would be a practical choice for a future console because the technology is already used in graphics cards, laptops, smartphones, and other compact devices. Its modular construction could also make production and servicing more manageable.
The PlayStation 6 remains unannounced, so any connection between the patent and the final console should be viewed cautiously. Still, the design shows that Sony is considering a different approach to heat management as it prepares for its next generation of hardware.
