The beast of an engine that is Qualcomm's Snapdragon 810 mobile processing chip is known to make hot rod smartphones faster—yet hotter than anyone would like.
Adopters of Qualcomm's hottest mobile processor have had to work out ways to keep their handsets from overheating, and a torn-down Xperia Z5 Premium shows Sony's solution to keep the Snapdragon 810 from running too hot.
Sony's solution is the use of dual heat pipes, established to transport heat away from the Snapdragon 810.
In an image of a torn-down Z5 Premium, posted to Chinese-language microblog Weibo, two pipes, likely copper, run across the top half of the Z5 Premium above where the battery goes in.
The processor itself, which intersects both channels near their centers, isn't visible in the image. That's because its smothered in thermal paste, a compound meant to manage the heat transfer from the processor to the heatsink and protect the two components from having metal kiss metal.
Generally, the philosophy in heatsink applications is something along the lines of "more is less," but it looks like there's an apron of aluminum protecting other circuitry and sensors from Sony's heavy-handed application of the paste.
The Snapdragon 810 is the fastest mobile processor Qualcomm has to offer, fast enough so that manufacturers are willing to work with the company and work out the kinks of the chip.
OnePlus has taken a similar approach with the OnePlus 2, applying thermal paste and graphite to keep the recently launched handset from overheating.
"Just like we did with the OnePlus One, our engineers debated endlessly over which CPU would be the perfect fit for the 2," said OnePlus. "While we played around with other options, we always came back to the 810."
The OnePlus 2 operates within the industry's standards for phone temperatures, even after hours of use, said OnePlus.
"We worked very closely with Qualcomm's engineers to integrate an improved version of the chipset (version 2.1) in the OnePlus 2, and fine-tuned both hardware and software," OnePlus stated. "The 2 will be 'cooler than ever.'"
