So I've officially done the mod. All I used was a .5mm shim without thermal paste because I'm out at the moment. Its running at a minimum of 5 degrees celsius cooler. I did order a thermal pad to take its place and it should be running even cooler after. As for antutu I've scored about 4k higher as well. I haven't even seen the high 60s let along 70 degrees yet. Running temp is between 40-55 celsius I've idled down to 35 so I think everyone whose conferrable with taking your g3 apart should run a thermal pad. My screen does feel warmer but its honestly not really noticeable.
[G3 General] russnash:
I did this mod today while I was bored at work on new years day, one thing I did notice though is that my VS985 doesn't have a metal chassis for the thermal paste to transfer heat to. It's plastic. That said though, there still seems to be enough heat transfer to make a difference.
[G3 General] sabresfan:
Just did this mod same as op and I notice an immediate improvement. My power and volume buttons would get hot but its definitely cooler now. Thanks for the great video tutorial.
[G3 General] oogsaggie:
Hea all. Was just wondering if someone had some quality thermal pad material leftover to get rid of. Would much rather buy someone here a pint than the vultures selling crap on EBay. Cheers.
[G3 General] theshrink89:
Anybody tried the silicone thermal pads? Are they worth it?
[G3 General] ThePurpleK:
Standard thermal pads work well (forgot their material), but ended up using a copper shim + thermal paste. The results weren't much different.
[G3 General] tunichi01:
any update for those who did this mod months ago? any long term negative effect? on the screen?
[G3 General] TheMadScientist:
Nothing but great top out at about 60 c but average 40c but i also did a couple extra chips while i was in it
[G3 General] Haribo68:
I used a stack of 2 tiny 0,5mm ARCTIC Thermal pad, 6W/mK, 10x10mm.

When the thickness is to big you can press it to a smaler thickness.

I made the thermal softmod too, change the thermal-engine8974.conf in /etc, and all its fine.

I used it for 1 Month. I´m not a havy user but when i need the speed the speed is longer high.

The Display is ok and almost placed in the front.
[G3 General] Ev_da_bacon:
I'm not gonna give you exact temps but the screen hasn't shown any problems other than being warmer where the cpu is. The buttons and camera are cooler and my phone has been fast and reliable with no issues ever since doing this in mid november
[G3 General] tunichi01:
thanks for giving the exact brand you used :) also, didn't you use thermal paste? just pads?

Thanks for your help guys :D

Hello everyone,

today I applied thermal pad, temperature went down perfectly. But I found big drop of wifi signal. I have low signal in living room and sometimes the wifi going off for a while.

Did I something wrong?

[G3 General] smatak:
Very nice, and what about your wifi signal? Do you have some signal drops? Because I have :(
[G3 General] Itachi23:
wifi signal is working fine, i'm not a heavy user of wifi, but so far, no problem at all.
[G3 General] adil.ali.503:
which one is more safer for cell

thermal paste or thermal pad?
[G3 General] Akopps:
How hot is too hot? When I pushed my LG G3 through mass application updates through play store or other heavy tasks, the back cover does get warm. I checked the CPU info and often some sensors go up to 70C under heavy tasks. No wonder the older LG G2 actually tended to post more consistent benchmarks. My G2 used to get something like 900-ish all the time in Geekbench 3. The G3 can get 900-ish on the first run, and 700-ish on a subsequent run.
[G3 General] marcdw:
I really don't know. I thermal pasted some months back. No issues.

Like any liquid (albeit thickish) there is the chance it could run, though. So technically a pad would probanly be safer. I already had paste on hand so I used it.

[G3 General] Nicky2108:
I applied this mod... When I bought my phone... It's hot in the camera zone when I play games and now... The heat spread out to the whole frame... Its hot slowly now and cool down very fast...
[G3 General] Leeum:
I just did this on my LG G3 D850 as my phone would get really hot up to 75-80 degrees. After the thermal paste method it reduced to 60-70 degress. Thanks heaps mate. P.S. I didn't use as much as the video
[G3 General] o1d8oy:
I did this mod few days ago. So far no issues and phone no longer gets hot around power button.
[G3 General] AlwaysLucky:
Paste/shim method is sheer overkill. Remember this is a SoC, not a CPU/GPU. The same heatsink principles do not apply. Go with a 1mm thermal pad and cut it down to 90% of the size of the SoC. Pre-press it to about a 0.7mm thickness. Clean both surfaces with alcohol before applying. Ensure you tighten all screws as tightly as possible without stripping. If you want to do it right, you could even re-apply blue loc-tite to the screws when re-assembling.

Thermal pads will stay flexible when hot which will allow the screen and frame to flex like it was designed to. Paste usually hardens like a rock after getting hot, sometimes creating rainbow colors when you press on the the middle-top portion of the screen. There have also been reports of the GPS antenna contacts not being able to touch due to the thickness of the thermal paste after it gets hot. Pads are also much easier to clean off if you ever need to remove it to send in for warranty.

I have been using the thermal pad now for my gf's G3 ls990 and my G3 ls990 for just over 4 months now, and we are both still seeing the consistent 10+ degree (Celsius) drop during heavy usage. I highly recommend using this mod. :D
[G3 General] whitexp:
what would be best in the opinion of you?

thermal paste, thermal pad, or heatsink (I saw a thread where it was placed)?

thanks
[G3 General] ads2801:
In my opinion you need use thermal pad or thermal paste for a heatsink due plastic LG G3 cover. Buy one heatsink on ebay, and apply thermal paste or thermal pad. Obviously is best use a thermal pad, due to you doesn't use a liquid component, so is less dangerous for the phone, but If you doesn't have a thermal pad, use thermal paste being carefully, no exceed too much, use only a little quantity of thermal paste.

PS: Sorry my english, I'm trying to improve it.

---------- Post added at 10:17 AM ---------- Previous post was at 10:15 AM ----------

Thermal pad or thermal paste don't do nothing without a heatsink, or don't do much more...You need use both: thermal paste - thermal pad & heatsink for a best work.

---------- Post added at 10:21 AM ---------- Previous post was at 10:17 AM ----------

Thermal pad and thermal paste, don't interrumpt your connectivity, despite it has metal components. Wifi and 3G/4G and others goes perfectly, with no problems. However you need be carefully aplying thermal paste and thermal pad, and later apply the heatsink.
[G3 General] arrows83:
What would be an ideal heatsink?
[G3 General] AnteLo:
You should add litle bit under metal heatsink.

Lg G3 Bootloop, Restores wont fix it, please help!

My Lg G3 is rooted, has the Lg G5 ROM on it and has TWRP recovery installed. The other day i was playing a game, went to tap the screen and the phone froze and died. When i tried to boot it up again it was in a boot loop. So I decided to try and restore one of my backups from a few days ago. However, I just got the same result after the restore. The phone was in a boot loop.

I have tried wiping and restoring to different backups but nothing is any different. One thing i have noticed though is when on the TWRP recovery main menu, after going into mount it says that the system is not mounted. Does this have anything to do with the problem? Dont know if this is the right place to post but if anyone has any suggestions, please go ahead!
[G3 General] spongerobsquarepants:
My G3 has been doing random reboots, this seems to be due to overheating of the CPU which was 70C, after i monitored it on CpuTemp. Is this normal behaviour for the phone to be rebooting due to CPU overheating? I have put in a new battery as I originally thought that would be the issue. Would this thermal mod fix work for me, or does it seem like there is something more to my predicament?
[G3 General] ThePurpleK:
I've reached that temperature in the past without the thermal mod and doing the mod very noticeably lowered the temperature. The mod *will* help. Aside from that, you should take a look at your kernel settings, especially the governor and throttling settings. Changing kernels may help you.
[G3 General] spongerobsquarepants:
I am on stock marshmallow rom and not rooted, so would need to be rooted right? Are there any kernels you recommend? Also, how do I sort out the governor and throttling settings? I'm completely new to this. Thanks.
[G3 General] ThePurpleK:
You need to be rooted. As a CyanogenMod user, I can't give advice on stock kernels and settings, unfortunately. However, I can suggest that you use the conservative governor as it is less taxing on the CPU.
[G3 General] spongerobsquarepants:
Is the cyanogenmod stable you are using? I've used cyanogenmod on my S3. Do you know the reason for reboots? Is this likely caused by the CPU overheating?
[G3 General] ThePurpleK:
I use the latest nighties. Be warned that battery life is not very good with CM13 (three hours of screen on time), but I'm fine with that. The reason for the reboots is most likely overheating.
[G3 General] spongerobsquarepants:
I guess there's only one way to find out. I did notice a Dirty Unicorns stable rom. I assume that'd have those settings to change?
[G3 General] ThePurpleK:
I don't know about that since I haven't been on stock based ROMs for ages now. You should ask there.
[G3 General] spongerobsquarepants:
I applied the thermal paste to the cpu and put the phone back together. However, the phone still continued to reboot. With little usage it was fine for a day but as I started to use it more over the next 24 hours, it again started to reboot itself. This was with temperatures of the same as without applying the thermal paste.
[G3 General] ThePurpleK:
I think rooting and using a custom ROM/kernel would have to be your solution. Then you'd be able to use the conservative governor.
[G3 General] Taracair:
Can anyone confirm that after 1-2 years of usage everything is fine with the LCD screen? The heat is redirected to the screen so in my opinion it may damage it after long time.
[G3 General] marcdw:
I did the thermal paste sometime last year. So far no issues with regard to screen and heat.

Never really felt the screen before until your post just now. It is indeed warmer than the back of the phone. We'll just have to wait and see.

[G3 General] tiguy99:
Did the mod today.

Used Fujipoly 11.0 W/mK 0.5MM thermal pad.

Take a look at Antutu

Was surprised bc the new version has horrible frame rates for the 3D testing part

See attached for the results

As for the temps

Idle is between 35-40C

Phone normally runs between 45-55C for average load

Max temps I've seen are 73-74C but I had some benchmarks and other apps going.

The phone is smoother and the screen isn't hot at all.

It's luke warm at the top at Best while the back of the phone is slightly and I do mean slightly warm.
[G3 General] tiguy99:
Oh yeah by the way here's today's screen time shot...keep in mind i did a lot of CPU intensive crap.

I'm excited to see standard screen on time tomorrow
[G3 General] King_Tuna:
Hey guys which one should i use thermal pad or thermal paste. I got zalman stg2 for paste.

Im really afraid to damage something. Is it easy to do? I hit 95C on one of my cpu-z thermal sensors while stressing cpu with stablitytest 2.7

I do a lot multitasking on phone and it throttles itself down! I hope this helps.
[G3 General] tiguy99:
Pad...much easier and more effective in my opinion...

BUT since you have it try the paste sparingly
[G3 General] King_Tuna:
If pad is more efeective then i will go with it. Thanks!
[G3 General] arebokert:
I did the mod about a year ago now and the screen is fine. However, I used a copper shim, and I've noticed that lately my GPS has been acting out and not locking in properly. I removed the shim today, as I said about a year from when I did it, and the GPS works fine again. Beware that using a shim might mess with your GPS lockin.

The screen is working without any issues at all and looks exactly like it did new so if you've got any thermal pads, use those as I think the mod is great as long as it doesn't mess up your GPS or wifi.
[G3 General] Driftfire:
yes go with pad, even though it's less effective than copper shim, but it's a bit overkill and also interrupts with the GPS signal, if it's not being interrupted then the copper shim mode is awesome :good:
[G3 General] Taracair:
So I'm going to do the mod soon. Do you prefer 1mm thickness or 0.5mm? Or maybe different? Is 12 W/mK good enough?
[G3 General] PTGamer:
no problems at all, had it since day 1 on my lg g3(it has 1y and 2months). i didnt use the thermal PAD, just a tick ammount of thermal Paste ( the cpu is in contact with the mid frame). no LCD problems or anything related.
[G3 General] zerotong1008:
after reading all the post, I still have a question of the thickness of the pad, should I by 1mm thick or 0.5mm thick pad to apply in this MOD?
[G3 General] tiguy99:
0.5mm is generally what most of us buy. Have been using for about a month and phone stays cool with no wifi, nfc or gps problems either
[G3 General] zerotong1008:
Thank you for your information, I have ordered a 0.5mm from Taobao, as I am living in Shanghai now.

Hope that pad is real.

Will update the result once I finish the MOD.
[G3 General] tiguy99:
Look forward to it!

Think youll be pleased with the results
[G3 General] SmuTech:
I still have wattanty on my G3. My question is: When i remove the pad and the paste an screw all back together as it was when i have bought the phone will lg notice that i applied the mod or will they just repair it? (Just in case anything breaks (not caused by the mod or by me)
[G3 General] Taracair:
Your warranty is void after thermal mod or any kind of software/hardware mod. There is a chance that someone will not notice the mods, but sincerely I won't count on it.
[G3 General] Version 7:
Excellent advice but as many have stated, use a thermal pad rather than the paste. Measuring the indent in the frame plus the distance the processor is below the EMI shield is approximately 0.6mm - so a 0.5mm pad will not be enough. The thermal pads I use are very soft, so a 1.0mm pad worked perfectly. Be sure to apply to the processor and not the indent of the frame to assure that the pad doesn't end up contacting the EMI shield which may result in a clearance issue.
[G3 General] tiguy99:
I used fujipoly 0.5mm thermal pad and had no issues.

In fact it works very very well.

Some people have complained that 1.0 caused issues with Wi-Fi and other signal problems.

As always your mileage may vary
[G3 General] android94301:
Killed GPS, would using a nonmetallic thermal pad help??

The mod is easy, and I used a .5mm copper shim, with thermal paste, but it has mostly killed my GPS. Where before the mod my phone locked in immediately, now it can take up to 5 minutes to get a fix, which makes using Waze or Google Maps impossible. I guess the mod is coming out. Have people who used nonmetallic thermal pads experienced the same GPS issues?
[G3 General] android94301:
Okay, so I removed the thermal paste and the 1mm copper shim. I replaced it with a stack of two .05mm Fujipoly / mod/smart Extreme X-e Thermal Pad - 100 x 15 x 0.5 - Thermal Conductivity 11.0 W/mK from Amazon, these were cut to about 13mmX13mm, and I crushed them down a little bit so they were probably 0.7mm high before I put them in. I put both on the SOC. Then I very carefully reassembled the phone, screwing the top screws and the camera screws first, and making sure they were all pretty tight, as the problem with the GPS is caused when the microscopic tiny metal contacts on the motherboard don't make contact with the plastic casing where the GPS antenna is. I didn't try bending the contacts as they are truly tiny, and with my old eyes, even reading glasses didn't help see them. Also, I think they are fixed contacts, and very tricky to bend.

All fixed, now back to getting a fix in 2-4 seconds. Yay! Temps are a solid 46 to 53 C even when running Stability Test.

I also had added the thermal software mod, which may also be helping. I'm back to loving my G3.
[G3 General] Biou_Pilgrim:
I just used my thermal past on my D855 ! Now, i m going to run PokemonGo for 1 hour. Let see how much my phone will burn my fingers !!

Edit : Truly amazing ! This mod is a success !
[G3 General] tiguy99:
Glad this worked out for you guys!

Loved it with my G3
[G3 General] AlwaysLucky:
It's actually not a matter of metallic pads, I found that it is a matter of thickness. The paste/shim method is a no-no because the paste will expand slightly and harden after heating. The shim will not help because the heat has nowhere to go when the phone is closed up. The GPS antenna uses touching contacts that will not touch if the paste or pad is making too much of a gap between the SoC and the frame.

I measured the gap for my two G3's at around 0.7-0.8mm, so I simply pre-pressed a 1mm thick thermal pad down to about 0.6-0.7mm and cut it down to 15x15mm. Any pad will do because the heat coming from the SoC is is actually not that much, but it tends to build up because of the design of the G3. Then tighten up the screws as much as possible without stripping.

Been using the pads for over a year and a half with no issues. The screen gets a little more hot than usual, but the SoC stays a consistent 10 degrees Celsius lower even after all this time. Had a GPS issue with a 1mm pad, but after measuring the gap and pre-pressing the pad, all was well.
[G3 General] panamamike:
Which version of the MOD did you go with? Shim, pad, only paste, combo?

What was the temperature delta?

Regards,

Mike

---------- Post added at 02:41 PM ---------- Previous post was at 02:23 PM ----------

Shouldn't the .5mm shim work if you have .7mm of space? Also when thermal compound expands like that, it's not as effective. Should be a very think layer, basically painted on.
[G3 General] Biou_Pilgrim:
Which version of the MOD did you go with? Shim, pad, only paste, combo?

I only used Thermal paste, but i think i ll loose some benefits in the futur so i m considering to use pad instead of my thermal paste.

What was the temperature delta?

About 10-15°C (From 65°C to 50-55°C)

Mike
[G3 General] DMCrimson78:
Just ordered some SARCON® GR45A from Fujipoly, 1mm thickness. I've this yellowish spot in the upper left quarter of my display... Need to have it checked first with LG, and see what they think, as the device is still under warranty.
[G3 General] Taracair:
Can you take a photo of it? You think it's because of the pad? I've just ordered some 1mm pad and I am concerned about such issues. How long have you been using the pad?
[G3 General] DMCrimson78:
I'm not using a pad at the moment, all stock. But from what I've read, the spot is caused by heat. Sometimes after extensive gaming my power button is so hot that it almost burns my finger... Lowering the screen brightness doesn't help.
[G3 General] panamamike:
Paste suggestions?

I've seen a few different variations of this fix:

1: Paste

- Gap too big for paste, can dry out over time and be messy.

2: Shim

- GPS signal block issues?

3: Thermal pad.

- Looks like the most promising.

That being said, I'm going with the thermal pad approach, but I'm wondering how much can I use? Most have applied to just the CPU Snapdragon. I'm thinking if the phone chassis is being used to distribute the heat, maybe use a wider strip of the pad to cover more area on the chassis, wondered what other folks thought of this approach.

Also, are there other chips that could be added to the thermal pad, or should they be left off of contact since they don't get as hot?

Your thoughts are welcomed.

Regards,

Mike Hoffman
[G3 General] Taracair:
Tomorrow I am doing the mod with thermal pad and I was thinking about the same - to cover more area. I will let you know about my thoughts later.
[G3 General] tiguy99:
Used the Fujipoly 0.5mm (11 m/mk) costly but worth it.

Cut to fit the soc and never had issues.

Only dropped temps 15-20c avg across the board :D

Go that route.
[G3 General] AlwaysLucky:
I used a thermal pad on both of my G3s with great success. Only cut it to just under the size of the SoC (aka CPU) chip. I think the chip is around 15x15mm, so cut the pad down to ~14x14mm. I measured the gap between the SoC and the chassis at around 0.6-0.7mm. A 0.5mm thick pad will work, just make sure to press firmly during initial install and re-assembly.

The amount of heat that we are sinking from the SoC is tiny compared to the Desktop CPUs and GPUs that the thermal pad is meant to be used with. With this in mind, the quality of the thermal pad is irrelevant. Get the cheapest non-metallic pad you can find and you'll be good to go. I bought a $6 pad for both of my G3s and I achieved the same drop in temp as those who spent a lot of money.

I hope my experiences help! Good luck! :cowboy:

---------- Post added at 11:47 AM ---------- Previous post was at 11:41 AM ----------

The SoC is the only chip on the board that creates any tangible heat. Cut the pad to just under the size of the SoC (14x14mm) and you'll be good to go.
[G3 General] Taracair:
Done. The mod is amazing. I used 12wmk thermal pad, 1mm thick. I pressed it a little with fingers and it fits perfectly. I have maximum 60°C when charging and using GPS and mobile data. Previously I had 75°C and the throttling was lagging the phone.

I do recommend the mod with thermal pad.
[G3 General] panamamike:
Thanks to all. I ended up using the Arctic thermal pad 6.0 W/mK. I applied a .5mm pad across the width of the chassis and just covered the chip with a square. The results are pretty good, temperatures are matching my Sammy Galaxy S5 which was running anywhere from 10 to 20 degC cooler than the LG G3 without the mod. The screen doesn't seem to get any hotter than it did in the past, so happy about that too.
[G3 General] Taracair:
Well there always must be some drawback. I am experiencing weaker WiFi signal after the mod. Anyone has the same issue?

Maybe it's because my pad is too thick? I used 1mm one.
[G3 General] no14me:
anyone confirm?

this mod look interesting :D
