Jup bye bye warranty... But if you carefull maybe you can clean all up and now one knows... And be gentle to the screws... I don't see any Warranty sticker... But with luck you don't need the warranty.
[G3 General] ride_bmx_mhell:
yes i done this,but in my way

i add copper shim 0.4~0.6mm thickness,,also i put thermal paste between copper shim ram side and lcd side and in emmc side i put thermal paste between copper tape and emi shield.

using wifi,youtube,chrome and debloated v30n + greenify and dose mode i get good results:victory:
[G3 General] android94301:
Just a heads up about this mod in general. I did it to my LG G3, and while it lowered temps, it ruined my GPS function permanently, even when I removed all shims and paste. So I can't recommend it. At least for me, overheating with GPS working is better option.
[G3 General] scarlet_venom:
Ok so I had some time to do this now(thermal paste with foil) and I can confirm it doesn't work, to a degree it does evenly distribute the heat and it is unnoticable, but after a while, it's back at heating up again at one spot.

But ofc it still depends on what thermal paste you use and what rom/kernel and if u play games, I used a cheap nonbranded thermal paste and I play 3d intensive games.
[G3 General] Taracair:
What was the purpose of the foil?

Just buy thermal pad, pre-press it and it's done.
[G3 General] scarlet_venom:
It serves as a heatsink so the heat doesnt go straight to the screen, also they dont sell thermal pads here, and ppl that sell pc stuff online dont like to ship(i mean local sellers, i dont buy from u.s. bec id rather feed poverish children with the expensive shipping fee lol), so might as well use watever is available for me.
[G3 General] Taracair:
The purpose of the whole mod is actually to use the screen as a heatsink. Paste without foil should do the work.

I think the foil was isolating the heat instead of passing it further. But that's only my opinion and maybe I'm wrong.
[G3 General] scarlet_venom:
I googled it, aluminum foil is a thermal conductor. And yes my screen does heat too, just not as hot as that guy in the reddit that turned his screen into a toaster, maybe I dont need the foil but I'll keep it this way anyway since I never had any wifi signal problem.
[G3 General] Taracair:
Remember that proper kernel settings help you with the maximum allowed temperature.

Thanks for explaining the aluminum foil issue.
[G3 General] scarlet_venom:
After a while I decided to just remove the thermal paste for two reasons:

1. One time i was letting my phone download something 700mb and the heat started to build up, I checked cpu-z and it's going over 110 degrees celsius, battery is 48 degrees and it is draining like crazy. So I wouldn't just say it doesn't work, but I'm gonna say it doesn't really work and it's just a placebo.

2. There are a lot of LG service centers in the country, so I may have my device repaired by them, if that time ever comes.

Also other stuff that I changed is that I went to Kernel Adiutor and turned down my thermal throttle to 70 degrees(for turning down cpu frequencies) and 80 degrees(for closing cores). It used to be 80 and 90.
[G3 General] Taracair:
It wasn't the fault of the thermal mod, it was the fault of your kernel settings. I have set 66°C for throttling.

If you're using custom kernel be sure to configure it properly. Wrong combination of governor and hotplug may lead to a situation like you described.
[G3 General] ST Dog:
Any idea what they charge now?

I've got a G3 that was baked once. That lasted a week then could recover by baking. (I found this thread too late to try)
[G3 General] vanko11595:
Where in kernel adiutor settings you turned down thermal throttle to 70 degrees(for turning down cpu frequencies) and 80 degrees(for closing cores)?
[G3 General] scarlet_venom:
I haven't asked them yet, but you can call their official customer support.

This depends on your kernel, it should show as "Thermal" in one of the options, tap on it then it should take you where it has sliders to change the throttling, otherwise if it only shows Core Control and VDD Restriction toggle(without the sliders) then it means the guy that made the kernel didn't add the option to do so.
[G3 General] vanko11595:
It shows only toggle. CrDroid 4.2 is the ROM with kernel. Which kernel adds those options for android 8.1?
[G3 General] Taracair:
XTD Kernel, artx kernel, solid kernel, mountaser kernel.

Thermally Conductive Adhesive tape

Hi, did someone use a Thermally Conductive Adhesive tape like in the adhesive copper foil video? This way there shouldn't be gps problem and it should spread the heat across the motherboard and not to the display.

Do you think this could work and would be better to avoid damages to the display?

Did someone have problems with the display after using a normal thermal pad ?

Thanks
[G3 General] AlwaysLucky:
My gf and I are going on 4 years now with both of our G3's using a 0.5mm thick thermal pad. No heat or reception problems at all.

I've posted a few step-by-step instruction on this thread that is far easier than the OP's procedure, and doesn't risk any reception issues. Reception issues derive from using thermal paste that expands, or too thick of a thermal pad. If it's too thick, the GPS (and sometimes wifi) antenna doesn't make contact because of the bulge created by the thickness.
[G3 General] marcdw:
[MENTION=6061535]AlwaysLucky[/MENTION], my beloved D851, 2014 to August 2018 (R.I.P.), was originally thermal pasted back in 2015. Since then I've read and learned more. On my third G3 now (can't live w/out it. LOL) and forgot how hot the thing can get.

I may consult your previous post and thermal pad this one. [emoji106]

[G3 General] eric93se:
I recommend people do a real benchmark to see more accurately how and if this mod works for you. I have a D850 with RR Oreo, XTD kernel, stock "thermal engine", Alucard governor and hotplug. Running "stress cpu" app I hit 75C 100% cpu usuage. After applying a small amount of thermal paste to the SoC and a 0.5mm silicon pad to the metal shield I still hit 75C at 100%. I only ran the stress test for ~1min where temps stabalized. I don't know if 75C is a thermal limit from the thermal engine but cpu usuage stayed at 100%.

Interestingly, I didn't notice, in "stress cpu" app you can watch the cpu speed throttle and it did quite a bit. Cpu was set to a max 2.4GHz and throttle up and down from 1.4GHz to 2GHz and occasionally hitting the max set cpu speed.

Help Lg G3

Hello,

I have Lg G3 and it overheat a lot, I use a thermal pad but don't work. Maybe I use in the wrong way, can you help me?

regards,
[G3 General] AlwaysLucky:
If you saw zero difference after installing a thermal pad, I would guess either one of two things are happening:

1: The pad is not thick enough (0.5mm thick thermal pad is usually perfect thickness) or you have the rare Korean version G3 that has a covered SoC chip.

- or -

2: Before installing the pad, the G3 overheated extremely bad. To my understanding, when any silicon chip overheats past a certain temp, the chip tends to overheat easily in the future; regardless of any cooling solutions you may use. This used to happen often to me when I was into overclocking my desktop CPUs and GPUs.

I'm guessing it's the first possibility. If you would like more assistance, provide more details about the pad used, your exact G3 model, and details regarding the installation.
[G3 General] tolakos100:
Can i use thermal paste between gpu and thermal pad for more efficiency?
[G3 General] _voldemort_with_a_nose_:
Putting a strip of aluminium foil on top the paste fills the gap completely.

Or put a piece of paper on the ribbon beside the camera to put pressure on the motherboard to make its contact with the heatsink
[G3 General] 3of12:
No, op was right from the start. Thermal paste has higher thermal conductivity, and the spacing is only about 1 mm, you just need to apply more paste than normal. Thermal paste is non conductive, so you can make a mess if need be, and it drys after applied. I build custom PCs as my main hobby and I recall my phone overheating easily, so when I looked inside I was shocked to see an aluminum heat-spreader with no TIM whatsoever.

The next step to consider would be some way to mod the heat-spreader to improve transfer and dissipation, and I thought of a way that might work. One, you could solder a copper shim to the gap on the heat-spreader, then use either thermal paste and improve the efficiency, or apply liquid metal and greatly improve heat transfer; it just requires some extra care. To use liquid metal on laptops and embedded devices, just cut some strips of electrical tape and made a seal around the area of the die coated, so it cannot leak. Two, increase heat dissipation by applying TIM to the contact point between the heat-spreader and the phone chassis. The downside of improving the cooling system of a phone is that it makes the phone chassis hot, and this is why its better for the chassis to be built out of aluminum.

I have currently only applied a thermal pad, but I've already seen results, but 5 mmins before throttling isn't enough, because I want to use this phone for VR applications.

---------- Post added at 01:03 AM ---------- Previous post was at 01:01 AM ----------

That's not efficient enough.. You'd need thermal paste on both sides of the foil and two interfaces is always worse than one.

---------- Post added at 01:06 AM ---------- Previous post was at 01:03 AM ----------

Thats not how overheating works. The soc throttles to avoid failure temps, and to actually damage an IC you need much higher temps. In the case that it reaches failure temps while throttling, it just shuts off. Smartphones throttle after only a few minutes of full load, in the case of the G3, it only took 5 mins with a thermal pad that was actually thick enough.
[G3 General] Pacote-san:
Had no idea that g3 didnt have at least a thermal pad...

Took me 10 min, now the heat spread so much better with the heatsink (used AS5)

thanks
[G3 General] bloodclot:
It was always on my mind to do this but I didn't go through with doing it until now.

extremely pleased with the results, temps dropped -10~-15c using GC-EXTREME gelid.

Used a little bit less than the amount used in the video
[G3 General] OtakuLi:
for sure! But better solution for cooling :D
[G3 General] OtakuLi:
no problem man, as long as the phone is save ;)
[G3 General] lixxus:
just wanted to give you guys a heads up.

so i bought a copper shim about 0.5mm and also some double sided thermal adhesive 0.3mm.

and i can say that my overheating has completely gone. the phone does get "warm" obviously its summer here in uk, especially after heavy use. but it is not like before where the top part of screen gets hot etc. that has all gone.
[G3 General] mo123456789:
Does the copper shim go in between two pieces of adhesive pads?
[G3 General] drotaru:
Tried to do it on my lg g3 cat6 .. Not the same design .. SoC is encased in a metal hetspreader .. Or atleast thats what i think it is .. Still seems not to touch the metal body of the phone has anybody else tried it on a F460 ?
[G3 General] pletpetplet:
Hi all,i got d855 and i play a lot games.After 10 mins.play my cpu temp. is over 80°C :( nothink can help using euphoria rom with 777 kernel r10.My question is if i do this this mod can he couse any hardware problems on the divice or not.Sorry for my bad english.
[G3 General] imucarmen:
it's safe. Just do it already!

---------- Post added at 09:13 PM ---------- Previous post was at 09:10 PM ----------

Just did this today and the results are amazing. Temps went down 15-20C

I used some artic MX-4 paste and a .5mm thermal pad. Just put a dab of paste on each side. Results are amazing!
[G3 General] copy2050:
i already have recomended this for a lot of people, for long time and i did it myself to my G3, i have to say, temps go from 62/68º degrees to 40/45º degrees, is way easy to do, fix a lot of issues with the phone and raise up the scores in every benchmark!

antutu before give me 36/37k to now give me 44/45k is awesome and i feel the phone less laggy, more responsive!

try it, but make sure to follow the video to do it right.
[G3 General] pletpetplet:
Thank u for respons...i need to use thermal pad with paste or i can use only paste like on video.
[G3 General] gokhandroid:
You can use whichever you want
[G3 General] biustech:
i used a themal pad and thermal paste, my results are not interesting. still running hot on certain occasions
[G3 General] copy2050:
i only put thermal compound Artic Cooling MX4, is the best, for me works, but other users say have put a thermal pad, i think is a good idea too, because have sure they are in contact with the processor and dont heat up and go for other parts of the phone board!

do what you want, i guarantee you be more in love with your phone with this mod!
[G3 General] Blackfox123:
After reading this I'm no longer sure if I should buy the G3 of not lol. I had the G2 but I don't think it was getting that hot
[G3 General] xdax1:
nice mod!! Will it work as well just by using thermal pad? I afraid I got too much paste on and mess up the phone later
[G3 General] angwar90:
Will this affect battery life a lot?
[G3 General] theoverfiend:
In therory yes but I think you will not see any differently
[G3 General] Kigsuha:
Can anyone one confirm this wont destroy the phone in the long term?
[G3 General] robogo1982:
To be brutally honest, from a perspective of a former G2 owner: don't.
[G3 General] :
Aside from the laser AF and 4K screen, the G2 and G3 are the same phone. The 800/801 isn't too different. I guess the 3GB of RAM is more important, but I wouldn't upgrade (even w/o heat issues, which I don't have).

No, because it most likely will depending on how long you use the phone, and how good you are at hard-modding.
[G3 General] EternalFlame:
Hello, thanks a lot for the guide mate, now my phone runs cool and smooth as *

You're awesome !
[G3 General] saccentekennedy:
Hey there... I'm in London too... do you know where I can pick up the shim and thermal adhesive? Is it something that Maplin carries?

Thank you in advance!
[G3 General] Gr8man001:
Bought the thermal compound for less than $4 at a local Radio Shack, applied following the instructions, and heating issues are gone. You really don't need expensive thermal paste. This compound has worked for me on many other electronic devices, laptops and PCs. It sounds like a sales pitch but just wanted to let you know that this compound and OP instructions are working great for me. Thanks!
[G3 General] liamR:
Will 15x15x0.5mm thermal pad be the best way to go?

Thanks
[G3 General] Kimd41:
I also want to know this, 0.5mm or 1mm thermal pad?
[G3 General] aaronc222:
Don't know how I didn't stumble across this before but I just did it this weekend.

I didn't take any before readings but the heat issues on this phone stopped me from playing CSR Racing. The phone would get so hot after 1 or 2 races that throttling took over and made the game stutter so bad it was unplayable. After the mod I can run a full set of races (10 - 12, run out of 'gas') and it still plays as smooth as the first race.

Info on my phone/how I did the mod:

VS985 (Verizon)

Only thermal paste w/out foil/pad/shim... (Shin Etsu Microsi, I have tons of it lying around from work, they give us 1/2 a syringe per heat sink replacement)

Total time from start to finish was under 20 minutes including the 5 minutes to stop and make my 7 month old a bottle

After Mod Temp:

Wake/Unlock 35c

Idle/Browsing/Email... 40-45c

Moderately Complex Game (Clash of Clans...) 53-55c

Complex Game (CSR) 65c

Side note: This has to be THE easiest phone I've disassembled to date. I've done a couple iPhones (3GS/4s) and a few Androids (Droid X2, Incredible 2, Galaxy S3) and this one was far and away the most pleasant experience I've had to date.
[G3 General] OtakuLi:
Very nice, seeing a lot of good result from this mod :D

Thank you for all the supports!
[G3 General] zerotong1008:
what is the dimension of ths SoC? it is 15mmX15mm or 20mmX20mm?

thanks for the info! im planning to try this by tomorrow
[G3 General] Zlatty:
This is such a blatant design flaw on LG's side. However, it's nice to know it can be amended by 5 minutes of time and some thermal paste. Looking forward to testing it on my phone tonight.
[G3 General] Zlatty:
I applied the thermal paste to my LG G3 and the phone works for once. I can stream videos at max brightness without setting anything on fire. 20℉ temperature drop all around.
[G3 General] gado45:
Didn't know this could be achieved , have some artic silver 5 left from my pc setup definitly gonna try it
[G3 General] liamR:
Guys be careful not to use conductive (electricity) thermal paste if it leaks to the PCB it can kill the phone, check your thermal paste before applying.
[G3 General] bogdan003:
What paste do you use?
[G3 General] liamR:
I'm using 1mm Arctic Thermal Pad .
[G3 General] NERDTUBED:
I've actually been thinking about doing this to mine, but i'ts partly due to laziness and well.. Mostly that, but awesome that it's working :D

#EDIT

Just did it, and we'll have to wait and see if I can feel a difference or not.
[G3 General] tetrahedonism:
Just did this myself, and I gotta say that LG makes one sturdy phone. When I took apart my old Note II, that thing felt so flimsy.

I'll be posting stats in the next day or so on how it's performing!
[G3 General] zurih:
Any suggesions on how to remove a thermal paste? I used a cheap one and it doesn't do a lot and I want to applu a better one.
[G3 General] petermg:
You can try an alcohol pad, or dip a q tip in alcohol and try that, but you could first just use a facial tissue to wipe off any excess, then use the alcohol to get the residue. This is what I did. Worked for me -I used an alcohol pad and some qtips.
[G3 General] skui:
I use to use ear cotton swabs with ethanol, but it's better to use propanol ( or propylic alcohol ) that's more pure and less aggressive for the components.

I don't suggest pads or papers because they can do scratches and leave small pieces here and there, and that's not good for the phone.
[G3 General] arebokert:
Do you guys think this would work to put between the cpu and the chassis for better contact?

http://www.ebay.com/itm/10pcs-Coppe...5-15mm-/291374947627?var=&hash=item43d74cdd2b

[G3 General] biustech:
i didn't measure m8, but i would say 15mmx15mmx2mm
[G3 General] Racer-1:
15mmx15mmx0.5mm. 2mm is way too thick.
[G3 General] Liberr:
I'm getting a G3 in a few days. According to the video in OP, some G3's have a overheating issue, so I guess not all. I was wondering: is this due to use (for example overclocking) or is it a problem with the hardware (the CPU not making proper contact with the casing > should it?) that varies with different models or something?
[G3 General] Racer-1:
The phone gets hot without overclocking and yes the SoC is a little away from the casing. That's why a lot of people took thermal pads, thermal paste or coppershim and put them in the phone and it really makes a big difference.
[G3 General] arebokert:
I ordered a pack of 15mmx15mm and a range of thicknesses from 0.8mm to 1.5mm. I'll report back on how it goes when they arrive.
[G3 General] RoyFAR:
Nice experiment bro ;)

Btw have you ever opened G2? Does it same like G3?

[G3 General] Kigsuha:
Okay Thank you, what can i except after doing this mod ?

45°c or 50°c in the same situation ?
[G3 General] dadi11:
Maybe 45c from that what I read there.. I still can't decide to do this mod, because of increased screen temperature with it. but my device is running up to 75c

Sent from LG G3
[G3 General] Racer-1:
It's not really increased. Without the mod my cpu was running at about 80 degrees when charging and normal usage in a quite hot room of about 28 degrees celsius.

With the copper shim mod it runs at about 60 and the screen is not hotter than before.
[G3 General] arebokert:
What thickness is your copper shim?
[G3 General] Racer-1:

how should I do it? paste>copper pad>paste? or just paste>copper pad. what do you think about adding some isolation between pad and LCD?

Sent from LG G3
[G3 General] Racer-1:
I did paste-copper shim-paste. Why a isolation? The point is to dissipate the heat not to isolate it and heat up the chip again.
[G3 General] gado45:
Maybe to protect the lcd ? Does anyone have some feedback after using this mod for more than a month, the lcd is not affected by any means ?
[G3 General] Racer-1:
I bought my G3 last year in July. About 4 months later I installed a thermal pad. In march I had to sent my G3 in because of a cracked bezel. That were about 5 months without problems.

The screen got replaced with the bezels. After that I applied the thermal pad again until about 3 weeks ago. At this point I installed my copper shim.

No problems so far.
[G3 General] Kigsuha:
How much better is the copper shim against thermal pad?

I heard that the copper shim can kill the phone if u messed up.
[G3 General] dadi11:
that's exactly what I thought about..

Sent from LG G3
[G3 General] Kigsuha:
So are there any confirmed size for thermal pad / copper shim ?

No ? Planning to buy some.

Thanks
[G3 General] arebokert:
How can the copper shim kill the phone exactly?
[G3 General] menvert:
I am going to try this mod, but I will use K5 PRO (find it on eBay) from Greece apparently?

It is a Thick thermal paste that is apparently several times better at heat transfer than thermal pad, but it can also bridge up to 3mm (looks like it's basically a clone of what Apple uses in some of their hardware)

So to me sounds like best of both worlds - a paste that can span a variable gap size but without the poorer performance a pad will give...

Anyway I am excited, I was shocked to see my CPU at 60-70 just from light use
[G3 General] r.sorujlall:
interested in trying this also with some thermal paste. decided to go with Arctic Silver 5 but just as a use posted a little while back i'm worried if spreading the heat out towards the lcd will cause issues in the future.

i'm in south america so warrenty and future repairs is pretty much out of the question unless i ship any parts and tools i'll need all the way to me and do the repairs myself which i don't have a problem doing but shipping to my country is not exactly cheat so if that could be avoided would be great
[G3 General] Racer-1:
With the copper shim the temp gets down more quickly and the phone throttles at a later point.
[G3 General] Kigsuha:
Okay thank you do you know what size for the copper shim ?

I ve read that most people write to put thermal paste and coppet shim but why ?

And what order for the paste copper ?

Thank again
[G3 General] Racer-1:
It had been posted a lot of times. 15x15x0.5mm. That's the size of mine and it fits perfectly.
[G3 General] Kigsuha:
Okay thank you did you do it with thermal paste + copper shim or only copper shim ?

Edit :Nevermind
[G3 General] Racer-1:
With paste on both sides. That works best.
