First Galaxy S7 teardown reveals the liquid cooling system

First Galaxy S7 teardown reveals the liquid cooling system
It's barely been a day since the Galaxy S7 and S7 edge were announced to take on the smartphone world by storm, and the Galaxy S7 already has its very own teardown treatment, watertight chassis or not. A Russian tech blog has gotten their grubby mitts on an S7 unit, and gave the trusted heat gun a bit of work to disassemble the back panel, and expose the internals.

First off, the Galaxy S7 indeed has a liquid cooling technology inside, how cool is that? We don't know, but it is built on some intricate flat copper piping with a tiny amount of liquid housed inside that is weaved around the CPU/GPU combo to take away the heat that the new Exynos 8890 and Snapdragon 820 chipsets would generate under, say, gaming stress. Samsung put a specific emphasis on the gaming abilities of its new handsets, as the phones support the new Vulcan graphics, and it has even created a dedicated Game Launcher that will minimize notifications and other disruptions while you game. The excessive heat generated by the GPU in these scenarios will now be taken away and distributed more evenly, thus avoiding any chance of overheating, freezes or shortened motherboard lifespan.

The other interesting observation that the folks who disassembled the S7 had, is that there is only very strong and watertight adhesive gluing the rear cover to the frame, no rubber seals around, so they began wondering whether you could lose the IP68 waterproof rating if you leave the phone for a prolonged time in the heat somewhere, or if you take off the cover in a repair shop to replace the embedded battery or the screen. The other takeaway is that the power button is built on a very sturdy mechanism, and is unlikely to break easily with time, which sounds reassuring. Take a look at the first Galaxy S7 teardown below.

Samsung did say they made the s7 waterproof form the inside, over stopping it from going in,if that means anything, no idea, but that what they said?

damn this phone has its own a/c...this is a plus.

Just like the phones with S810, if you know what i mean :)

Yeah when Samsung does it then its a like natural wonder of the world. But when the 810 phones (Z5 has DUAL heat pipes) copied this tech from PC's, they were being bashed left right and center. PA should be ashamed of their disgusting behavior.

No they were being bashed because the pos 810 was still overheating

BET in 2017-18 smartphones will come with built in cooling fans ..

The only thing that sucks in this phone is the exynos. Pretty much sd820 version is flawless. I hope that the phone has no 4k recording limit finally. Otherwise, I'll be greatly disappointed.

I ve seen some antutu benchmark tests where the exynos scored higher than the sd820. But even if it had a lower score, it is still getting more than double what 2015 was scoring. So I fail to see how it sucks.

He's a Snapdragon fan. He can't accept that he's Cpu is crap. Comparing it to the Exynos. Though 1 good point the SnapDragon is more Dev friendly.

Looks, for android muti-score is better so I do not give a crap what antutu says I more about geakbench says and that ver close single core and a killer muti Also the m1 keeps the score on many tests

The SD800 was fast enough for me. From here on out it's all about power efficiency and I can't wait to read about which one performs better. I'm probably going to go with the G5 though so I guess it won't matter anyway.

SD has more wide developer's support. This is the reason I want SD. Otherwise, what Qcomm did last year is not forgettable.

The Exynos is more powerful. Exynos chips were always underclocked to meet same expectations to the SnapDragon variant. Or-else Exynos destroys the SnapDragon. Due to heat. Now they've used cooling system to reduce heat. They should've used an advance version and use the Exynos Soc at standard or uprated settings.

Sammy had to OC the exynos to keep up with the sd820, not the other way around. 810 was crap and exynos was amazing in 2015, but now the tables have turned. I'm not disappointed with the exynos cpu as much as I am with the crappy mali gpu that comes with it. Andreno has always been superior. That's the problem.

Exynos is actually underclocked LOL. Exynos 7420 was 772 MHz on GPU, 8890 is just 650 MHz. Talk to me again when proper tests are done. I'm pretty sure both will be pretty much equal.

I was just about to write that, but you beat me to it. He's a Snapdragon fan boy. It really hurts him to gob the truth.

Underclocked but probably bigger cores.


Posts: 1168; Member since: Oct 05, 2015

It should be underclocked with 12 cores! I like this approach, though. Not sure about Adreno's architecture either.

That "crappy" Mali GPU beats "not crappy" Adreno since 2011 every single time.

No, Samsung released underclocked prototypes for testing purposes.

Exynos graphics aren't as good

Because Mali Gpu are 100mhz lower than the SnapDragon.

Why I sense hiden agreement between Quallcom and Samsung?

Wait for the real proper tests by reputed sites who know what they are doing in field( like anandtech or tomshardware), before coming to conclusion. Currently it looks like Exynos has 20% faster CPU and 10% slower GPU. It may change(for better or worse) with final software/hardware. Also keep into account that mali and powerVR are usually faster in real life games than adreno GPUs.

What I wonder is if those websites will get the phone before launch. Basically, are we going to see proper tests before launch date?

18. TyrionLannister unregistered

I don't think so. Anandtech will release the review around early-mid April. They take their time but the end result is worth it. i prefer a late review which I can trust over an early half-baked one.

Damn.. I've been waiting for S7 to come out. But I think I was hoping for something slightly better (mostly in the camera department - still no info w.r.t. slow motion capabilities). Especially to go for a pre-order buy. Nonetheless, I don't see myself waiting for iphone 7 (which is unlikely to have a huge improvement camera wise). Decisions, decisions.
