Samsung’s thermal throttling problem is old news. The Galaxy S22 controversy, the GOS scandal, years of Exynos heat complaints, the community has been pointing at this issue for a long time. What’s new is that Samsung appears to be doing something genuinely different about it. Reports confirm Samsung has established a dedicated thermal research team investigating active liquid cooling and gaming-grade heat management for future Galaxy phones.
The timing makes complete sense. Modern flagship workloads are nothing like they were three years ago. On-device AI processing, real-time image generation, 4K and 8K video recording, Galaxy AI features running continuously in the background all of it generates heat that traditional vapor chambers increasingly struggle to manage. Software throttling has been Samsung’s answer for years. The company is apparently acknowledging that the answer isn’t good enough anymore.
The technology Samsung is reportedly evaluating works by circulating coolant through a sealed internal loop continuously moving heat away from the processor rather than simply spreading it across a vapor chamber and hoping for the best. It’s the same fundamental approach that RedMagic and ASUS ROG have used in gaming phones for years, but Samsung reportedly wants a quieter, more mainstream implementation without visible fans or dramatic design compromises.
Separately, Samsung has already shipped something concrete in this direction. The Exynos 2600 inside international Galaxy S26 models includes Samsung’s Heat Path Block (HPB) , a copper-based heat-transfer structure integrated directly into the chip package that reduces thermal resistance by up to 16% compared to the previous Exynos generation. The design required moving DRAM away from its traditional position on top of the processor to make room for the new thermal architecture. The result has reportedly caught the attention of both Qualcomm and Apple, who are said to be evaluating similar approaches for future chipsets.
No Galaxy model has been officially confirmed to receive active liquid cooling yet. The Galaxy S27 series is mentioned most frequently in speculation: future Snapdragon and Exynos chips pushing AI performance even harder make stronger cooling even more necessary.
Samsung has been reactive about heat management for years. Building a dedicated research team and shipping HPB in production hardware suggests that’s finally changing and Galaxy S27 buyers may be the first to feel the difference.
