Sony has registered a patent for a redesigned cooling system that could address one of the most debated features of the PlayStation 5: the use of liquid metal as a thermal interface. The filing, recorded in early 2026 and published in April, describes a heatsink architecture intended to improve cooling regardless of whether a device is used horizontally or vertically.
Details of the patented cooling design
The patent outlines a new heatsink capable of enhancing heat dissipation for electronic components across multiple device orientations. According to the document, the design’s goal is to maintain efficient thermal performance whether the console is placed flat or upright.
The text does not explicitly name the PlayStation 6, but industry specialists cited in the source suggest the technology could be part of Sony’s research for a next-generation console.
Why liquid metal on the PS5 became controversial
Since the PS5 launch, Sony has used liquid metal between the processor and the heatsink to improve heat transfer. While effective for many units, the solution prompted debate after some users reported internal leaks in consoles that experienced overheating.
At the time, speculation arose that operating the console vertically might encourage liquid-metal movement, but Sony never confirmed a direct link between orientation and the reported issues.
Recent PS5 Slim and PS5 Pro revisions
Users who examined the PS5 Slim and PS5 Pro models noticed internal changes to their cooling systems. These later versions feature redesigned heatsinks and adjustments in how liquid metal is applied.
Technical analyses indicate those modifications could lower the risk of leaks and improve thermal distribution, though Sony has not publicly detailed the reasons behind the changes.
Patent does not guarantee PS6 implementation
The filing should be seen as a technology record rather than confirmation that the design will appear in a future product. Manufacturers commonly patent innovations that never reach consumer devices.
Still, the document signals that Sony is actively exploring alternatives to enhance console thermal efficiency as expectations build around a new generation of hardware.
