Samsung unveiled the use of its Heat Pass Block (HPB) technology in the Exynos 2600 to help lower thermal resistance and improve heat dissipation. Based on rumors, there has been a lot of interest in this solution, with even the Snapdragon 8 Elite Gen 6 Pro schematic leak shown to be using it, which is a pleasant surprise because lots of manufacturers have incorporated custom cooling fans to help lower temperatures. While these additions have their use cases, the noise generated would definitely trigger some unease for users. Thankfully, a tipster says that the use of HPB will eliminate the need for these fans.
As chipsets’ power requirements rise to deliver increased raw performance, the Exynos 2600’s Heat Pass Block could be a viable solution
On Weibo, Fixed-focus digital cameras says that the new thermal solution can improve heat dissipation by 20 percent, with his previous posts stating that Heat Pass Block can allow chipsets like the Snapdragon 8 Elite Gen 6 Pro to reach clock speeds of 5.00GHz. This solution will be highly beneficial for Qualcomm, as the latter has been pursuing an aggressive approach with its SoCs by targeting higher clock speeds to obtain improved single-core and multi-core scores.
The Snapdragon 8 Elite Gen 5 for Galaxy is expected to reach 4.74GHz on the performance cores, and that will only result in increased heat generation. To combat this problem, companies like REDMAGIC have adopted custom fans in their smartphones, but to say that they’re distracting is an understatement. Also, even with these fans doing their job, the Snapdragon 8 Elite Gen 5 still experiences situations where its thermals are sitting at uncomfortable levels.
For instance, in a graphics and framerate comparison of Tomb Raider 2013 running on the iPhone 17 Pro Max and REDMAGIC 11 Pro, the A19 Pro was operating at a chilly 39 degrees Celsius, while the Snapdragon 8 Elite Gen 5 was running much hotter at 47 degrees Celsius. As for how Heat Pass Block technology works, it is essentially a heatsink placed on top of the chipset die to help transfer heat. Since the DRAM on top of the chipset also produces heat, there’s little thermal room for the SoC on older designs to flex its muscles properly.
Thankfully, this limitation gets addressed by the Exynos 2600’s Heat Pass Block, but we wouldn’t be this quick to pass judgment on a solution that hasn’t witnessed any real-world testing, so while it shows promise, we’ll wait for actual data to come through and conclude if high-performance smartphones still require fans or not.
