[Nexus 6P General] DarkNate34:
This does make me curious. What kind of heat dissipation element does the Samsung Galaxy S6 has?

My old S6 Edge had issues with the camera that Samsung could never fix, when they opened it, I got a chance to see some of the internals, it very thin materials.

I'm now on the S6. My question is, how does it keep the heat under control? I can play a game as simple as Alto's Adventure and in a few minutes temperature reading apps would report 60°c.

I originally thought it was a bug, but these are two different devices, both full different states and in a different time period. My uncle has the S6 Edge too, same readings.

Want to hear the odd part guys? The front of the device is no more than about 35°c and the back never crossed about 40°c (depends on battery temperature). How can I tell? Well Celsius is off the boiling point of water and it is easier to relate.

Anyway, point is, it doesn't feel like the phone is running at 60°c. Any ideas?
[Nexus 6P General] hakneo:
I will not say anything else. Nice guide, effort and daring mod. Thanks for giving a starting point.
[Nexus 6P General] spaha-bih:
so basically what you did is just removing old thermal compound and putting new?

for me this does not sounds very difficult, i would like to try this with my Z5, but the biggest problem is removing glass on the back.
[Nexus 6P General] Degrated Shadow:
Makes me wonder if this was so easy for a manufacturer to control thermals with a TC paste then why haven't they done it already.. Seemse to me the metal lids and the connectors to the metal back did much of the dissipation.. And with the better thermal paste it should be better..
[Nexus 6P General] Gorgtech:
Ok, I´ve updated the OP again ( see the Tests section ). Now I´m really done with Benchmarking on this phone and wasting my time to compare several different results. I guess I made my points clear that this modified device is still in a great condition and at least the modification didn´t change the cooling for the worse? ;)
[Nexus 6P General] ataft:
I see in the OP you updated with benchmarks... But where are the benchmarks to compare to from before the mod? Or more importantly: where are the temperature comparisons?

I can appreciate what you've done here, but it's hard to judge what worth, if any, this mod may have had.
[Nexus 6P General] salimbest83:
just sharing when i work in Intel.

we use thermal paste between a CPU die and heatspreader.

to ensure no airpocket, we use thermal paste in the middle of die with [X] from top left to btm right. and btm left to top right.

almost exacly like this ( but in factory enviroment )

[Nexus 6P General] Gorgtech:
Thanks for all paste related suggestions again. I´ve opened the device one more time and checked the areas. What can I say? It was not such a mess like many of you might have expected. I´ve cleaned the device again and started all over.

This time I managed to fit the Eisschicht 17W/mK Thermal Pad between the SoC and the lid and it seems that this one is usable and doesn´t need that much pressure to adjust. I´ve used the "drop" method for the thermal paste this time, and simply used the pressure of the lid to spread the paste.

I´ve performed a few tests and will continue later again. What can I say? I don´t see any difference at all to be honest. It´s like the previous Mod. Oh well, wasted some time to "fix" something which was not broken. That´s the price if you do something in the name of science.

I´ll edit the OP later and add the Eisschicht Pad pictures too.
[Nexus 6P General] aniketkuber:
Hi op, since you have opened the device can you add something to the structural design of the 6p, which all have been complaining about, especially around the volume buttons. Is the metal too weak there? Whats your view on this?
[Nexus 6P General] Gorgtech:
Phew, this would make some guys mad but here is at least my opinion. My device suffered too from a slight warp and noticeable gap between the display and the buttons. When I removed the back 2x, it still looked 100% flat on a table.

The Aluminum back is quite tough but I´m still not sure if it would remain that way. I noticed however that the glue below the battery seemed to have softened too because of the heat and I gently pushed the battery against the frame. The sides of the back look very thin but in total this device seems to be somehow durable, though I have my doubts that the used layout is one of the best.

Now my device still looks flat and the gap between the buttons and the display frame is barely visible anymore. I guess that heat inside the device is what makes the battery go wild after a while. I´m not sure about the visible bent area though which other guys experienced. Maybe some of them really put their phone in their back pockets and have sit on it? Who knows ;)

I won´t open my phone a third time, it has slightly visible scuffs around the visor glass and the paint also chipped off around some edges where I used the metal pick. If you use a case, it doesn´t matter anyway because no marks would be visible.
[Nexus 6P General] mrdunlop:
How many of you guys who claim "Too much TP" actually have experience with that stuff? The stuff is dielectric so it shouldn't matter. It may look like the OP used a lot, but we are looking at a picture, and we all know that a picture doesn't tell the whole story. There are too many variables to make an explicit claim like that, you dont have drawing specifications for dimensions, size of gap, or even the specs for how much heat that soc needs pulled from it to function properly.

We are so good and quick to criticize someone for doing something that your average user wouldn't dare attempt. Bravo OP you are one brave Mofo!
[Nexus 6P General] galaxys:
Yes, this OP & thread is definitely in the spirit of XDA! Experiment, Explore, Improve, trial & error, Development...! Kudo's
[Nexus 6P General] Gorgtech:
Thanks, that's nice to hear ;) I hope that the Nexus 6p will last for at least 2 more years since I'm out of warranty now. For me it was worth the try and you gain extra experience, especially if you have to deal with such complicated devices.
[Nexus 6P General] WangGang:
Try doing it with coollaboratory liquid ultra. It claims to have a thermal conductivity of 38.4 W/(m*K)
[Nexus 6P General] Citizen_Snips:
Agree on the thermal paste replies. Don't judge OP.

Most of the people come here to flash mods to their phones that could potentially turn it into a brick, but you get all fussy over application of thermal paste? Yikes. Don't discourage him from trying future projects!

Thanks for this OP. I honestly won't try this unless my 6P starts getting exceptionally hot. The nerves are enough for me not to.

Reapplying the thermal paste on my old PS3 was so nerve wracking I almost threw away all the pieces and bought a new one. Like you, I also "used way too much paste" according to all of the video tutorials on YouTube(which instructed to use something like a credit card to apply a very thin and even layer neatly on the CPU), but I was young and figured more paste = cooler CPU. FWIW, it ran another year and a half before the motherboard finally gave out. Huge improvement over freezing and shutting down every hour while sitting directly in front of an AC unit. ???? Oh and 20 minutes without the AC. Fan was also working. Man thinking about it now, those things get hot, fast. Anyways sorry for the OT. Thanks again. Will definitely consider it if my phone starts overheating!
[Nexus 6P General] Gorgtech:
I've used this liquid metal paste a while ago and will never use it again. It is 100% conductive, very hard to apply and absolutely not reliable. I've mentioned it before in this thread. Even standard silicone thermal paste is better for long term purposes than this kind of liquid metal.
[Nexus 6P General] Bigbabyjesus:
I am thinking of replacing my back panel as mine is scuffed and camera glass is scratched. I'm considering changing the thermal pads or paste. Which would you recommend, pad or paste, and what thickness of pad do you think would be best if you were to suggest that over paste?

Replacement back with glass and bottom plastic is $40CAD on ebay and I figured I would order pads or paste at the same time.
[Nexus 6P General] Gorgtech:
A thermal pad between the SoC and the lid can be used if this one is very thin and can compress to a smaller size without high pressure. I used the 0.5mm thick Eisschicht Pad on my second try. If you cannot get a similar thermal pad with such a high thermal conductivity, use thermal paste instead.
[Nexus 6P General] stephendt0:
People have criticised because it is true. I have been working with PC hardware full-time for 8 years, about 12 years since I started tinkering with them. The OP has applied too much which is probably holding back thermal transfer, and in worst cases, oozing over to other components which could cause corrosion over a prolonged period. This picture is pretty much the ideal paste to surface area ratio:

[IMG="Ideal Thermal Paste Application"]http://www.circuitremix.com/images/124/apply_1.jpg[/IMG]
[Nexus 6P General] Gorgtech:
I just want someone to answer me one simple question. How deep is the gap between the SoC and the lid? Do people read the whole OP? If you don't know the exact gap dimensions, how can you tell that I still used way too much thermal paste? Why did the phone achieve better scores instead of throttling?
[Nexus 6P General] ataft:
I just checked out the Benchmarks thread and I'm seeing people running stock achieving pretty much the same score as you in Antutu.

I then start to think... A passively cooled device can only be improved upon so much before it can no longer transfer heat any more efficiently. Given that the 810 is known to get hot, and the 6p is a thin device, I'm thinking that Huawei did about as much as they reasonably could, within the design specs, to keep the phone cool.

Perhaps you applied too much paste, and any possible benefits were cancelled out... Or perhaps the possible benefits were just never going to be significant enough to realize a real world improvement in performance and cooling.
[Nexus 6P General] Gorgtech:
The cooling system of this phone is physically limited and like I said before, even replacing the paste with diamond sheets ( look it up ) would not change too much about it in comparison to the first and second attempt with elite thermal paste and thermal pads. Even this modified device will throttle sooner or later but it will require a way longer time in order to heat up. This will result in less throttling intervals which will make the phone feel snappier during regular use.

From a point of reliability, the new paste is also something which will help the phone to survive at least 2 more years, until you can chose another one from your phone provider. I did the Mod because I was curious and decided to also make a guide about it. Many Teardowns only show you a few shiny pictures without all details. It was OK for me to void my warranty because to be honest, I was willing to take a risk. Worst case I would have lost the phone but this is not something which would make you to eg. commit suicide?

Now, I´m no longer sure if it was such a great idea to make a guide if you read on the internet how other guys insult you for sharing something with a community.

Maybe I will open my phone once again (third time) and check if everything is still in place but on the other hand everything works great and this device is really hard to open.

I asked about the gap size because I eventually opened my Nexus 5 (2013) again in order to check if the Pad was still in place ( it was ) and also found the time to measure eg. the gaps and the material thickness. This phone is a lot easier to open. Since other phones use the same material, I have at least more input now.
[Nexus 6P General] ataft:
I don't think anyone here has insulted you, rather people have just pointed out something you did incorrectly, or in my case questioned whether the mod even had the desired effect (and offered a reason why it may not).

You've made some claims saying it greatly reduces throttling, improves cooling, improves Antutu results, and increases phone longevity... But you have provided absolutely nothing to confirm or prove that.

As it stands I think you did a great job getting the phone open and doing this mod. I would be more confident opening my phone after going through the OP. However, this thread should be labelled more as an exploration of the phone than a guide to improving it in any meaningful way.
[Nexus 6P General] Gorgtech:
Just have a look at that video: https://www.youtube.com/watch?v=r2MEAnZ3swQ

If you add "more" thermal paste, you can connect a larger surface with it. Assuming that the pressure used is the same in order to attach the heat sink, there is nothing wrong with it? It might look dirty or even be a waste of material. How exactly will something like this change the results for the worse? If you add a lot of paste and don´t apply much pressure, you can increase the gap between the SoC and the heat sink but this is not possible.

Why is it not possible? Because the whole motherboard has a really tight fit when it´s held in place by the screws. Some thermal paste is thick and not very soft but will adapt through heat to the surface because the mechanical pressure will work against it.

Like I showed in the extra pictures in the OP, more paste would only harm your wallet since you waste material and maybe create a huge mess. That´s it.

And I know that the gaps in this device are way higher than what you experience in a regular PC where thermal paste only has to fill the scratches of the heat sink itself. In this case you can expect a gap of at least 0.3mm ( SoC - lid ) and a extra 0.3mm ( lid - display frame ).

How can I prove my claims? Every system is different and many factors make a comparison next to impossible ( ambient temperature, used ROM, Apps, Kernel etc. ). At least I can speak for myself that this Mod has helped a lot to improve my user experience with this device. Maybe I had bad luck and the paste attached by Huawei was poorly done?
[Nexus 6P General] 12MaNy:
Great....now a bunch of inexperienced kids are going to try this and screw something up and then start a hundred complaint threads about it.
[Nexus 6P General] Citizen_Snips:
That's just not fair. Lay off OP. Mods like this have been posted in pretty much every device forum I've ever been a part of. Opening the GNex/N5 and adding a wire to an antenna to get better service, etc.

The common knowledge of every single mod (software or hardware) on XDA is that YOU are solely responsible for what YOU do to your phone. No one makes anyone here do anything. If they try this, then that is on them. So are any consequences.

Your post was entirely uncalled for and completely irrelevant. OP posted a very clear disclaimer in his thread before anything else like pretty much every single thread on XDA.
[Nexus 6P General] ataft:
First of all, I find it hard to believe that the mod helped your user experience "a lot". The phone is fast as hell to begin with, and does not suffer from overheating or heavy throttling in normal usage. With all the hype about the 810 being a hot processor, if all it took to improve performance "a lot" was a better application of thermal paste then it would have been done.

Second, how do you know what you're feeling isn't a placebo effect or something to do with a 3rd party ROM or kernel you're using?

You're essentially asking everyone to take your word for it... On XDA...
[Nexus 6P General] 12MaNy:
It was a joke. Jesus.....

It was directed at the thousands of idiots who dont read and then attempt to mod things and then try to point the finger when they screw up their devices. Obviously the OP knows how to tear down a phone like a pimp.

Calm down Felicia....
[Nexus 6P General] Citizen_Snips:
Since you don't seem to know it's very hard (read impossible) to read sarcasm. You know, for next time. ;)
[Nexus 6P General] hacksome:
Very cool mod indeed!. // No pun intended. ;)
[Nexus 6P General] 12MaNy:
Whatever dude.....
[Nexus 6P General] Gorgtech:
That´s nice to hear that the Mod helped you too in order to lower the thermal throttling intervals :) Is it OK for you if I link your post in the OP too? Like I said before, this device is really hard to open and not something which everyone would want to do.

Now you have used nearly the same ingredients as I did which should offer you a similar performance. Did you also try the heavier Benchmarks like 3D Mark or Vellamo?
[Nexus 6P General] RngrYogi:
I will be glad to run some numbers on them and hopefully compare them to the stock setup on the 6P! I love this kinda stuff lol and please feel free to link this to the OP. I will take some screen shots and see if I can get them attached here. If you would like some specific ones just shoot me a list. I'm so glad I can help. Thanks! :)
[Nexus 6P General] Gorgtech:
I´ve updated the OP. Some of the heavier Benchmarks are 3D Mark ( Slingshot & Slingshot Unlimited ), Vellamo and Antutu. It seems that you´re the only one after me at XDA who was crazy enough to perform this Mod too? ;) Any more volunteers?
[Nexus 6P General] RngrYogi:
And I can only admit to a small level of crazy. I think its more experience and confidence then anything else. I've been inside hundreds of different phones doing research and repairs. I am also a system builder of over 20 years so I have a lot of experience with cooling components and designing effective setups. I attached my latest baby in the screenshots. I'm so proud of her lol! So I have a lot of experience working inside phones and with hardware and software. About the only thing I have not fully tackled yet is coding but rest assured I'm on it! lol

Ok I have some screenshots for you guys!
[Nexus 6P General] ataft:
Great job on the write up. Looks like there's a good, measurable, benefit to doing a mod like this.
[Nexus 6P General] Gorgtech:
These are great scores and the temperature increase is also linear. You can also see in the 3D Mark results, how this device recovers from thermal throttling. The resulting score is higher than that of a Stock Nexus 6P.

I´ve linked the post as well in the OP and I feel honored that this Guide has been mentioned by the great Guru himself at XDA ;)
[Nexus 6P General] Tron82:
What about electrical conductivity? I know there are completely insulated thermal paste while others do not ... there are risks (for the Phone and especially for people), maybe when you plug the smartphone to a socket? when the paste overflows, it's ok simply a cloth to clean it even outside of the smartphone (or worse in the creeks)?

PS:I'm a newbie so completely unable to repeat this now (and perhaps ever) but I find it all very exciting, so forgive me for my stupid curiosity :p
[Nexus 6P General] Gorgtech:
Most thermal pastes are not electrical conductive ( their resistance is very high ). Even higher grade thermal paste is not conductive under regular conditions ( you would need a lot of pressure in order to make it conductive which is impossible to achieve, even with a screwed heat sink ). Liquid Metal on the other side is conductive and looks similar like quicksilver. This stuff is dangerous to use and unreliable since it reacts with the material itself and can also damage circuits. It is also very hard to apply. I had the pleasure to use this stuff and won´t ever touch it again. It´s not worth it.

You can clean the stuff with a cloth but make sure that you don´t discharge yourself through the components. It´s dangerous to wear eg. a pullover while performing repairs like these because of a static discharge. Just use a tooth pick or similar item to remove the chunks of hard thermal paste.
[Nexus 6P General] Bigbabyjesus:
So I'm thinking I'm going to open mine up and do this, I also watched some videos of the dudes with a shop in shenzen that pull 16gb flash out of iPhones and replace with 128. Thinking about looking into this for the nexus.
[Nexus 6P General] RngrYogi:
Well, If u need any assistance with the cooling mod let us know. I have pulled some chips off the xbox Motherboards before but I would not like to try it on a small mobo like this one lol. At least not my own lol

---------- Post added at 06:51 PM ---------- Previous post was at 06:46 PM ----------

After a few days of helping seat the pad and paste in its doing very very well for me. I'm glad I took the time and money to do it. Even after a constant burn in for say 25% of the battery and heating up the entire phone so far with a app called cpuburn I found the chip won't throttle past 900ish mhz and will stay at a constant 70C. I would not recommend people do this but it can assist in breaking in new TIM once your set and fixed on what you know you're going to stick with.
[Nexus 6P General] Gorgtech:
I don't have the equipment to remove chips from circuit boards;) Btw, I can confirm that the pads need some time before they perform the best. I'm still very happy with my devices now. There's no need for me to open the Nexus 6p again :P
[Nexus 6P General] Gorgtech:
I´ve optimized my thermal settings now and this device performs even better now ;) It runs slightly hotter but that´s not a problem at all.
[Nexus 6P General] badboy47:
Shouldn't it be less hot after optimization? From my understanding any phone getting warmer loses more battery. Assuming having it less warmer should help the battery?
[Nexus 6P General] Gorgtech:
It runs slightly hotter because I force it to run hot ;) It won't affect the battery life that much but will result in a snappier Os. You have to be careful though if you modify the thermal settings configuration file. Make sure that you don't overheat the battery.
[Nexus 6P General] RngrYogi:
Hey Gorg! Did you edit it yourself or are you working from someone's preset? I'd like to see what changes you made and and get me a copy to check out if you don't mind please post the conf file :fingers-crossed::highfive::silly:
[Nexus 6P General] Gorgtech:
I changed the file myself and experimented with different increments. I've increased the values by 4°C, even for the lowest settings. I can upload the file later ;)
[Nexus 6P General] aniel300:
Ok so i did this mod and used this thermal paste from Amazon (Arctic Silver Ceramique 2 25g Premium High Density Thermal Cooling Compound Retail CMQ2-25G) but now i see more lag than before please i need tips comments, help on what to do next
[Nexus 6P General] Gorgtech:
I'm not sure if this thermal paste is really suitable for this device? The gap between the lid and the SoC is quite large and would require a thermal pad or thermal paste which is sticky and not very fluid. Maybe this paste has managed somehow to spread around the components and to leave a gap after a while?
[Nexus 6P General] aniel300:
Yeah that could be or i put to much thermal paste, im gonna try put less and redo the benchmark tests, by the way im using Android n, does it effect the results? Also i have a square Peace of Copper, should or can i place it between the metal body and the cpu shield/ heat sink?
[Nexus 6P General] Gorgtech:
I didn't try the Android N Preview because this one might be full of bugs. Maybe the lags are not because of faulty paste. You could use a small copper piece if it's thin enough, about 0.3mm.
[Nexus 6P General] aniel300:
Ok cool
[Nexus 6P General] aniel300:
Update:used new/ different thermal paste, here are some screenshots but i still tink i can get better cooling. Should i buy the thermal paste u used amd tried with that ?
[Nexus 6P General] RngrYogi:
I would like to see the file and compare it to stock and see if I can make some tweaks i have been wanting to experiment with while keeping the battery safe. So please post it when u can. :highfive::p
