Samsung may finally be addressing one of its most persistent criticisms—overheating Exynos chips—with a surprising twist: a built-in cooling chip. According to trusted industry insiders, the Galaxy S26 series could debut a thermal control system (cooling chip) never before used in a Samsung flagship. The key? A component called HPB (Heat Path Block)—a copper-based heat sink that Samsung is planning to integrate directly into its new Exynos 2600 processor.
How the Galaxy S26 Cooling Chip Works
Samsung’s plan is to place the HPB module on top of the application processor (AP) and DRAM, following the PoP (Package on Package) structure. This way, the heat sink pulls heat away from both the chip and memory, helping to stabilize performance under heavy workloads.
Think of it like giving the Exynos 2600 its own internal heat exhaust system—one that works directly with the core hardware rather than relying solely on external vapor chambers or cooling layers inside the phone. If testing goes as planned, the Exynos 2600 will enter mass production by the end of 2025, in time for a likely Galaxy S26 launch in February 2026.
Why It Matters
Exynos chips have long lagged behind Qualcomm’s Snapdragon processors, especially in thermal management. But Samsung is clearly trying to change that. Even in early benchmarks, the Exynos 2600’s GPU—built with AMD’s help—outperformed the Snapdragon 8 Elite in 3DMark tests, a major reversal of past performance trends. The chip is built using Samsung’s advanced 2nm process, and it introduces a deca-core CPU layout with next-gen ARM cores and a new Xclipse GPU.
In short, this isn’t just a cooling patch—it’s a total architecture shift.
More Changes Coming to the S26 Lineup
The Galaxy S26 series is rumored to bring other significant hardware upgrades:
- A new Edge model may replace the standard “Plus” variant
- The Ultra model could support 60W fast charging for the first time
- More RAM, improved AI features, and possibly thinner bezels are also on the table
And while Samsung is still refining the Exynos 2600, the signs point to a much stronger global launch strategy, possibly with broader Exynos adoption in key regions.
