The PlayStation 5 has largely delivered a smooth experience, yet a lingering concern remains: the console’s tendency to overheat. While Sony’s liquid‑metal cooling system has proven effective in many scenarios, it has also sparked leaks and related complications in others. Though the precise cause of early PS5 overheating incidents remains unconfirmed, a newly disclosed patent—potentially tied to the forthcoming PS6—may address this flaw in the older design.
Filed in early 2026 and published in April, Sony’s patent focuses on a revised heat sink. The filing describes an electronic device that enhances the cooling capacity of a heating element built into a device capable of operating in multiple orientations. The proposal suggests a return to conventional liquid cooling, aiming to boost heat‑transfer efficiency whether the console sits upright or lies flat.
While there is no definitive confirmation that Sony will adopt this design in the PS6, the company appears to be moving away from its more exotic liquid‑metal approach. The debate over whether the PS5 should remain upright—after users discovered leaked liquid on motherboards—has long persisted, with many attributing overheating to the console’s orientation against gravity.
Although Sony never formally addressed the issue, the release of the PS5 Slim and Pro models brought subtle yet effective changes to the original heat sinks. Deeper grooves and altered application patterns helped curb unexpected spills and overheating incidents, offering a quieter, more reliable experience for early adopters.
If the PS6 takes the form of a handheld—or at least includes a handheld variant—Sony will undoubtedly want to avoid any leak allegations. My own PS5, however, continues to operate upright since launch, even in 97‑degree weather without air conditioning. For now.
❓ Frequently Asked Questions (FAQ)
What new cooling solution is Sony proposing for the upcoming PS6?
Sony has filed a patent for a conventional liquid‑cooling heat sink that replaces the experimental liquid‑metal system used in the PS5. The design incorporates a traditional liquid cooling loop with a heat sink capable of operating efficiently whether the console sits upright or lies flat, aiming to improve heat‑transfer and reduce overheating.
Will the new PS6 cooling design address the overheating problems that affected early PS5 units?
The patent indicates that the conventional liquid‑cooling system should increase cooling capacity and stability, potentially eliminating the leaks and overheating incidents that plagued some early PS5 models. While Sony has not officially confirmed the use of this design, the proposal suggests a significant improvement over the current liquid‑metal approach.
How does the proposed PS6 heat sink differ from the PS5's liquid‑metal cooling system?
Unlike the PS5’s liquid‑metal pads, which can cause leaks and are sensitive to orientation, the PS6 design uses a standard liquid‑cooling loop with a heat sink that is engineered to perform well in multiple orientations. This shift to a proven cooling method is intended to reduce the risk of leaks and improve overall thermal management.
