i was looking at the dissasembled xoom and for those who overclock there is a posibility that we can use the back cover as a huge heatsink by just putting in some heat tranfer materias on the cpu/gpu so it can make contact. Does it heat that much? i am wasting my time?

I am OC'd at 1.6 ghz and my Xoom has not gotten warm.
If it gets hot just turn down the cpu. I think that with the right ROM, running @1ghz is going to be fine. Adding insulation to the heatsink is only going to mask the problem.
ill check the temps with the cover off.. so far i can run @1.6 stable
the cpu is under a metal cover that is soldered to the board. and it doesnt touch the cpu because you can press on it and you feel when it touches it. lets see if i dont damage it when i remove it.. all pray with me
here are some pics of the us wifi xoom
I just watch 2 hours of tekzilla and hak 5. It never got hot and play great. I'm rooted 1.6ghz n loving it.
i have seen 37.8 C max at 1.6 interactive. I dont know if its too much or normal.
Must be ok. But the problem is i failed to find any kind of software to monitor the cpu heat.
I can only monitor the battery heat..

i've reached 42 so it's okay
operation break the xoom is on hold.... wife stole it for the day
operation break the xoom done its running @ 1.7 stable .. now im using the back cover as a heatsink and it actually gets pretty warm in that area.. so far so good .. will uplad pics later ..
here is the picture.. yeah yeah it appeared that i bit it with my teeth .. didnt found my dremmel cutting disk so i had to improvise.. as you see i put in a thermal pad that's connect to the back cover and use it as a heat-sink
5 hours @ 1.7 and rocking hard!

I don't have overheating problems, but I can only run at 1.6. At 1.7 I get reboots, even with the new Tiamat 1.0 Rom.
I saw a pretty cool stick-on carbon fiber decal/cover protector, but I am afraid that If I cover the back, the Xoom will overheat.
What do you think??
i dont think it will overheat it because the cpu dont touch the back cover
Since ARM has on-demand frequency scaling, are you sure you are running at 1.7 all the time? Did you actually lock the freq at 1.7, or is that a ceiling?
i just locked both sliders to 1.7
btw is not battery friendly
why would you lock at 1.7?? Except when Benchmarking???'
I think that you will ruin your processor if you keep it up, even with better cooling. The processor is just not made to run at 1.7 full time.

Thanks, but that's not my concern. What I am worried about is that the case will act as an insulator and not allow heat to dissipate through the back cover.
i locked just to see if it wa stable.. and so far so good. and for the back cover there are no worries because it wont make any diference.. im the one using it as a heat sink
Did you run a CPU-intensive benchmark for the 5 hrs? That's the only way to tell if it's stable.
Good to see someone willing to get his hands dirty with a mod. I have to say, though, that the +0.1GHz added speed is probably not worth invalidating the device warranty. Not sure why you have to cut the alum shield as opposed to simply removing it. Then, you'd have the option of reversing the mod if you ever need to RMA.
Anyway, onto the next mod: how to boost your wifi range.
Hi,
I've been using G2 for the past one week. Within minutes of playing a game( `10 mins), the phone heats up a lot at the back where the camera is placed.
I dont even need to play high end games like NOVA 3. Just regular games like Candy crush, Cut the rope etc heats up my phone real bad.
It heats up so much that its impossible to touch it with your hand.
Please advice if anyone has faced this issue.
Regards
Georgi

Same with me, but only plants vs zombies 2 may be its just one game.
Please don't post same question in more than one thread. Your question belongs in the question and answer section where you have it now also. Not here please.
Same here. Maximum overheating is seen during plants and zombie 2.
Hi,
Guys you realize that you have a quadcore at 2.26 Ghz... And when you play a (heavy) game or some other heavy tasks (browsing in 4G for example) it's normal that the CPU heats, right?
Temperature is very subjective without reading the CPU temp with an app, it feels hot in your hand (you can have cold hands and in this case you feel much more the heat) and it's hot because the CPU temp is about 90°C is different...
Heat and overheat (or "maximum overheating" like above ) is different too..., in any case there is a thermal throttling that prevent overheating. Our CPU shutdowns at 120°C so there is a little room... Even 80°C is nothing for the CPU...
Even 90°C for the CPU temperature is almost nothing (for the the stressed people) and there is a thermal protection in any case. Thermal throttling that reduces the CPU freq according to the CPU temp, same thing for the battery. And in case of extreme temperature -> shutdown.
And if you speak about "overheating" when playing a game or browsing while charging your phone...
Check your CPU temp with an app and report here...
It remembers me all the threads about "overheating" in the Nexus 4 forum...
I will definitely try installing a temperature app and will report the temp soon.
I'm worried that the heating takes place near the area where the camera is located. Can this have any adverse effect on the camera?

I cant vouch for a smartphone camera in general, but I know I had a newer regular old camera that sat in the sun and the heat for a day, and was perfectly fine. I don't see the heat damaging the camera.
How to tweak this kernel for stopping G2 from overheating? Even I lowered my CPU to 1ghz it is still overheating. :crying: please help. thanks
Hi,
What is exactly overheating for you???
Can you share your CPU/battery temperatures?
Overheating... But when? When playing a game while downloading a huge file over 4G and while charging?

After that you can try to undervolt a little (be carefull, step by step and don't set your undervolt at boot unless you're sure it's stable) and play with the thermal control by decreasing the max CPU temperature before thermal throttling...
You can use an app like Trickster Mod or Faux123 app (kernel enhancement) on the Play Store.

After playing heavy games, I can use my phone to iron clothes. lol. Well, I know it have quad core that's why I bought it. And I think having this kind of power is a disadvantage too because it heats very quickly like 10mins of heavy gaming.. And by heating it decreases the battery life.. I don't want to use this quad core phone in just browsing and watching video only, i bought this for gaming also.. lol
I don't know now where to use these quad cores.. lol... I envy my brother now, playing games smoothly on his ip5s with cool temp.. >.<
I have fauxclock and leave it to Intellithermal frequency throttle temp:80c and core throttle temp 85c. Is that ok?
Thanks :cyclops:
Re,
Hummm..... :laugh:
Decrease the two temperatures of 10°C... And use Ondemand or Interactive governor with MpDesicion "on"...
Try undervolt/underclock a little... No need to underclock at 1 Ghz otherwise, right, it will lag...
But I don't think you really understand what I was trying to say... Heavy games+quadcore 2,26 Ghz+10 mins of use with that...= heat (and not overheating), are you sure there is something wrong or abnormal?
What is your CPU/battery temperatures???
And please don't compare our CPU's with the one in the Iphhone 5, it's not the same thing.

Begin with -25 mV but don't set at boot, use your phone for a day like as always (games, browsing, etc...). If you don't have reboots or anything wrong then try another step by - 25 mV. If you went too low your phone will reboot, (so don't use the set/apply on boot setting or you could have a bootloop), at this point you"ll know the undervolt possibility. Apply your last setting before the crash and see...

Heloo i have the same problem when i play games likeplants vs zombies my phone hetas badly imen like 70°C(160°F) and i dont think it normal in like 10 to 15 min to be like that,i have root andtrickster app instaled and i alawys check the temperature.
I know its normal for the phone to heat but not so fast i seen thrads where users reported theyre g2 doesent heat bad att all.I have cpu threshold. on ,activated it from secret men.
So please helpwith advice and youre experience with this problem.
Thank you!
Hi,
Strif3, it's normal, point. 70°C is the CPU temperature limit before thermal throttling. What can I say more??? Read my posts above...
Use your phone like you want, as usual in any case there is a thermal protection! I think that Qualcomm knows how their SoC needs to be set about thermal stuff and I think (I'm sure) you can play heavy games without any issues even if your phone is at 70°C.
If your CPU temp was at 100°C (without modifie the thermal throttling), ok maybe here there is a problem (it depends also what you are doing), but I repeat 70°C during a game and after 10 mins i's totally normal!
If you all guys are worried about the CPU temperature, stop playing games, browsing in 4G and underclock your CPU to 300 Mhz and all will be fine...

Thnx for info
Stuck my phone in the freezer for a few minutes, took it out, and ran the stability test in AnTuTu which plots the temperature and a benchmark score. Looks like it starts right around 34 degrees (93 Fahrenheit), which really isn't that warm at all. You could get that just browsing around and holding it in your hand.
My cpu temp is normally in the 40's and 50's while browsing.
Have you tried turning the thermal daemon mitigation and high temperature property off in the hidden menu and see if this throttling happen? Will be interesting to know if the hidden menu selection works.

It does work. you can just open an app like setcpu and you'll see that it rarely peaks without disabling throttling. Just be careful as it does open you up to potential hardware failures and shorter life of the device. I only keep phones for around 6 months so I don't care but I'm not a normal usage case.

Wouldn't the hardware still have a thermal cut off point where it will just shut down the phone if it gets too hot? It's to my understanding that this hardware shut off point is different than the software thermal throttling. If anything, I think it will just make your device get too hot for comfort than do any real hardware damage to it.
I'm just throwing an educated guess out there though, I honestly have no real proof one way or the other.

Yes eventually it'll hit tjunction and shut down. This isn't even a safe shut down though. It is basically an emergency kill switch. It's like yanking the cord out of the wall on a desktop. Running at higher temps also shortens the life of the silicone. Much the same effect that overclocking has on a normal PC.

If it gets hot, it will do damage. It can fry the GPU before it even gets to shutdown point. The XBOX 360 for example had the RROD where the constant heat made the solder joints fail (I know the 360 is different but the heat point stands)

The 34 in this case is temp or battery, not SoC. The SoC is probably hit 75 Celcius and that's why CPU throttles. Try HWBot bench instead, it shows not battery but CPU temp. You will see that CPU immediately hits 75°

It runs hotter because its having to produce all the pixels for the QHD. The same chip in other 1080 phones doesn't run as hot. At times doing normal things like browsing and Facebook etc my phone has throttled down to 1.4Ghz max and the CPU temp is up at 65-70deg C. That's pretty hot.

Its not the only phone. And mine never throttles that low doing normal tasks. It doesn't even throttle at all. However, when playing games or running demanding apps it does throttle.
Also, its not the only phone that runs this hot. All other phones will get hot and throttle just as much when running equally demanding stuff.
So the question was, what's the point of super fast chips when they are going to throttle themselves so fast?

I'd recommend that you do a bit of testing,run some apps for 5-10 min then open up a CPU frequency app. The frequency will be be at a low maximum and the temp high. The GPU also throttles, open an app like Faux clock after running some apps and the max GPU value has decreased. Without a doubt the extra pixels are causing this as the SOC is having to work harder to produce them. Its simple physics.B
But anyway, its a specs game. People want faster and better so that's why the SOCs get faster and faster even if they're throttling.

The soc is working harder, but like I just said the how soc is still hot even on other phones man.
Run the dead trigger on the s5 and the g3. They both most likely throttle down to the same limit while the fps on the G3 might be a little lower due to the resolution.
But like I just said, what's the point when the damn thing will burn. There is no point in 2.5ghz when your phone can't run at that frequency more than 5 seconds lol.
I remember when I used to run my Galaxy S One full speed. Not one but of throttling. These CPUs have not gotten any more efficient thermal wise.

Yeah, I agree there's not much point in having a super fast chip when it throttles so much. Again, people want bigger faster and better and most users wont even know about thermal throtlling.It does seem to be bad on the G3 though. I think I saw another thread that said LG don't use a proper thermal pad also. Don't know about that but to run a 1080 phone with the same chip as a 2k phone then you'll have thermal and performance issues on the 2k Vs the 1080.

The 801 is more than capable of driving a QHD phone. The 800 series are basically created to support up to 4k. And how will give the same performance as a 800 while on QHD. Its not even close to being a big deal. And yeah I saw that same thread. I wonder if it's true.

I see that the layered CPU/memory unit has a metal cover to it, im wondering if a thin thermal pad could be placed between them to conduct heat to the metal cover. Its not much of a heatsink, but it might help a little bit. It may even be possible to put a thin copper sheet on the metal cover to move heat away. It all depends how much room there is under the plastic cover. The only teardown ive seen doesnt make it very clear.

While playing some games I noticed my phone(N910H/Exynos) has a very hard time keeping framerates once it heats up, I downloaded 3D mark and a frequency/temp monitor app and discovered that during Physics test my phone throttles at 92°C and keeps frequency at 1500MHz(simply can't sustain the 1900 supposed max) to prevent burning, how can the CPU reach 90° while my hands are barely any hot?. Then I watched some disassembly videos and turns out theres no thermal pad/paste between the CPU and "heatsink"(these older phones don't really cared for cooling,it sinks heat to the frame).I re-did the benchmark while applying slight pressure over the CPU area and my physics score went from 1500 to 1600, still reaching 90°C but taking a little bit more time to do so, so it kept 1900MHz for longer.
So I though about doing the experiment of applying thermal paste over the CPU, but i'm scared I may brake the phone on the disassembly, so I'd like to ask if someone is willing to do the test to see if it's worth it. Maybe we can unlock gaming potential we didn't know was there, thank you guys.
[Update] So I did the test
TL;DR: There's already a thermal pad there, so it's not like the results are shocking, it does make a difference but it's not worth disassembling your phone just for it.
BUT there's an additional experiment I'm gonna make sooo things could change.
WARNING: if you're thinking of disassembling your phone for any reason be warned that the spen digitizer connector is a little bit hard to connect so it happens pretty often that it won't work, so test the spen before reassembling everything.
Long version:
Anan did not publish the OC kernel yet but I was too curious and did the thing anyway, you don't need to remove the screen from the mainframe so the procedure is not really that risky.
Turns out that pinky thing I saw on the images are thermal pads (as anyone not stupid as me would already know), not copper as I originally thought, anyway since thermal pads are worse than thermal paste(even the 2w/mk ****ty one I used) I did replace it, I had to use a generous amount to make contact, after all it's replacing a thermal pad(0,5mm i think).
Overall CPU temps got like 5-10°C lower, but the benchmark results are pretty boring since they don't thermal throttle the CPU much, geekbench got 100-200 average more on multi core (no difference on single core) and antutu went from 99251 to 103408 ,CPU multi-score went from 26136 to 27971. The stress test basically achieves the same temps, only taking a few seconds more to throttle.
However,gaming performance did get a considerable boost,since they offer a constant heat output. Minecraft( yes it thermal throttles the cpu a lot) almost doesn't see throttles anymore granting a SIGNIFCANT better performance, Free fire also does perform better but stupid me did not pay attention to temps before the mod.
Heat on the phone also feels WAY less concentrated on the CPU area.
Now if you know a little bit about this stuff you know that thermal pads are usually used when the heat source is not touching the heatsink, which is the case here. I am 100% sure the results would not be this boring if the CPU actually touched the midframe, so I'm going to do another test sometime putting a 0,5 mm copper pad(401 W/mK vs the 2 from my thermal paste) to see the actual result I was expecting.
I know all this sound pretty stupid and pointless but I'm going to use this phone for another year or two so I want to make the most of it, also I really like this stuff.
If you want to know WTF is even going on you can watch this video/read the article: https://www.gamersnexus.net/guides/2137-thermalpaste-types-conductivity-and-more
I think someone has already done that, don't recall the thread
Use a kernel which can give you possibility to tweak. Search on Exynos forum.

A custom kernel would not solve this problem, as you need to get heat away from the cpu so it can maintain high power usage and low temps.
The only way a custom kernel would help the cpu run cooler is trough undervolting or increasing temperature limit, the latter is obviously dumb, about undervolting I have already tried managing mere -50mV wich did not change a thing.
So Anan confirmed he's porting Helios Kernel V3 to the lineage 15.1 rom (wich is the one I'm using) then well be able to overclock to 1500/2100. Once he posts that I'll see just how hard this phone throttles and then maybe do the procedure myself.
I got :
99251 on Antutu
1114 single 3734 multi core on geekbench
It throttles in both
the stress test in Antutu gets it so hot Im not really confortable letting it finish, it imediately reaches 90°C, keeps oscilating between 900 and 1900 on the big cores,in 5 minutes the entire phone is burning hot.
