Last week, rumors were floating around that Samsung was looking for a supplier to supply heat pipes for the Galaxy S7. And with other rumors stating that the device would be featuring the Snapdragon 820, many began to think that the Snapdragon 820 does indeed overheat like the Snapdragon 810. Over on Weibo, a Samsung Engineer decided to explain why they are using a passive cooling system on the Galaxy S7 and also explain that it doesn't mean the Snapdragon 820 gets hot.
The person claiming to be a Samsung Engineer states that thermal design is an art. He does also state the the operating temperature can affect the chipset's performance, but also states that having a passive cooling system doesn't always mean there is something wrong with the chipset. Instead it means that the manufacturer wants to take that extra precaution to make sure the device stays cool. And in doing so, it means the device will have a bit more performance, since it's operating at a cooler temperature. There is a rumor floating around that Samsung might be using a custom, overclocked version of the Snapdragon 820. Which would explain why Samsung is looking to use a passive cooling system. However that rumor is not confirmed.
Samsung is looking to do quite a bit with the Galaxy S7 this year. Not only do they want to sell more, as they always do and they should want too, but they are looking to bring back the microSD card slot. Something Samsung users have been accustomed to for quite a while. After last year's big redesign, it's now time for Samsung to refine that design and make it the best smartphone on the market. Which is an easy thing for them to do. Even with the faults of the Galaxy S6 and Galaxy Note 5 in 2015, it was still easily one of the best smartphones of the year.
Currently rumors are pointing towards a January announcement from Samsung. It's not confirmed just yet, but Samsung have sent out press invites for a press conference at CES on January 5th. Which we'll be there to see what the South Korean company has to announce.
