Haven't noticed this issue, I don't have before wi-fi signal readings to be sure, but wifi seems fine. I used a 0.5 mm thermal pad vs 1 mm, however I did double up on the SoC itself. Don't know how you decided to apply the tape.

My other thought is it could be related to reassembling the phone. The 4 clips, flexible connectors, you have to unfasten have a pretty noticeable 'click' when you reattach them, to the point I was concerned I might be applying a little too much pressure. Could be a poor contact? I don't know what the flexible connectors do. I know one is for the main camera, don't know what the upper right one does.

I'd also caution folks about the main clip near the camera assembly. You have to be careful with reinstalling and removing the mainboard, the ribbon fit is a little tight and you need to ensure the flat ribbon is properly routed through the available gap.

[G3 General] AlwaysLucky:
I had the exact same problem. My Wifi signal was very low and my GPS signal never locked. I found out it was the gap the pad creates . I also used 1mm thick pads, and I had to pre-smash them with two flat objects down to about 0.6mm thick, so that the GPS and Wifi antennas make contact. After pre-smashing them they expanded out a little bit, and I had to cut them down to 14x14mm again. Also be sure to tighten all screws as tight as possible without stripping, and if you want to be pro, use blue loctite. I hope that helps.

Edit: This is also why I strongly recommend against using paste/shims. Paste expands slightly after it gets hot, creating more of a gap than intended. After pre-smashing my 1mm pad, I've had perfect reception for both wifi and gps.
[G3 General] Taracair:
Thank you for your support. I did what you said and now everything works like a charm. Previously I have put too much and too thick pad. Photos 'before and after' attached. Now WiFi is fine.

Edit

As you can see second photo shows 1mm pad which was too much and how it sticks to the chassis with extra amount on the edges. I had to remove it, because of the WiFi. Other 2 photos shows 0.6-0.7mm pressed pad applied only on the chip.
[G3 General] bloodstorm666:
Anyone have a good cheap link to buy one of these recommended thermal pads???
[G3 General] panamamike:
This is what I used https://www.amazon.com/ARCTIC-Therm...1474587691&sr=8-6&keywords=arctic+thermal+pad

Cut to fit, remove clear plastic on both sides to apply.
[G3 General] bloodstorm666:
I just found an old Xbox 360 with some thermal pads, and shaved them down lol
[G3 General] AlwaysLucky:
That's what I used. Works great for what we're doing.

I don't recommend this. Thermal pads are meant to be used once. At 6 USD per pad, there really is no excuse to not use a new one. heh :cowboy:
[G3 General] panamamike:
Let us know how it works. BTW, I agree that it's better to use a newer pad. the pads loose their moisture over time and effectiveness. At least I've had that experience with thermal paste.
[G3 General] bloodstorm666:
Hmm. If its worth itnill buy it.

---------- Post added at 12:53 AM ---------- Previous post was at 12:52 AM ----------

Just the pad right? .5mm?
[G3 General] panamamike:
Yup, it's like a double sided foam tape. I used .5mm and doubled it up. I attached one to the chassis and one to the chip itself.

Mike
[G3 General] Taracair:
I don't think it's a good idea to double it up. It may lead to poor WiFi signal as in my case (few posts earlier).
[G3 General] AlwaysLucky:
:laugh: Do not do this. Use one 0.5mm pad on the SoC itself, or pre-smash a 1mm thick pad. Clean both surfaces with alcohol first.

The reason for this is that you want the heat to sink to the chassis only, not to the other components on the board. :rolleyes: Furthermore, you don't want too much of a gap between the chassis and the SoC, due to lack of contact from the wifi and gps antennas.
[G3 General] panamamike:
Not sure why you don't like my suggestion, it's pretty much the same as using a 1mm thick pad. Except you have .5 on the SoC and .5 on the chassis. Yes, I did flatten it some to avoid loss of contact.
[G3 General] AlwaysLucky:
Apologies sir, I misread your post. I thought you covered more surface area than the size of the SoC. It appears you just meant to double up 0.5mm pads only on the SoC. I should have read that slower :eek:

On that note, stacking thermal pads drastically reduces their effectiveness. The outside layer of the pad is made to adhere once to a clean flat metal surface. They are cheap enough that you can just buy the right thickness. A 0.5mm pad should be a perfect fit to avoid any antenna contact issues.
[G3 General] panamamike:
Thanks for the feedback No stacking pads :), that's good to know for the future.
[G3 General] dmxpeter:
I just used thermal pad. It was a bit bigger than I needed, so I cut is to fit perfecty into that square (chip). Then I ran Antutu and got score 61k. Surprisingly phone was really cool, I checked temperature in Kernel Adiutor right after benchmark finished and I saw 57°C. Before this mod I had about 80° with heavy usage. I am so happy :)).

latest AICP rom, Acc lite kernel 1.2, root, no xposed
[G3 General] kostelo:
I also did the mod today but I combined a slim piece thermal pad with a tiny bit of thermal paste. So now I have a cpu at least 10-12 degrees cooler. Before I had 80-82 degrees on heavy usage and now 69-70 tops.
[G3 General] dodgenator:

[G3 General] xdfly:
I have tried this a year ago and still to this day I'm using thermal paste it works amazing. I dropped my phone in salt water at the jetty and it was submerged for over 10 mins. Took the phone apart and dried it and reapplied the thermal paste again. the phone still works lg g3 is tough as ****.
[G3 General] Wimmme:
Just some feedback for you all before I leave this thread.

I did the Mod with thermal paste, i did it right, and it helped as described.

But some time later i got the dreaded SIM-card error issue, and my phone lost it's warranty because of the mod.

-> phone is pretty useless now. bought myself a nexus 6P (i don't regret that ;) ), but the G3 is waiting for some time to have the SIM-card reader replaced ...
[G3 General] marcdw:
Deleted. Misread previous post. Thought mod messed up SIM but I see it messed up warranty. Bummer.
[G3 General] imucarmen:
I did this mod a year and a half ago and it lowered my temps by 20+ degrees Celsius. G3 still going strong and never had a single issue with it. I still use my g3 to this day regularly. My post about the process i used are buried somewhere in this thread. I used thermal pads and a bit of paste.
[G3 General] frosty234:
Didn't want to read all through 36 pages, sorry, so I just ask:

What thickness of thermal pad do you recommend, rather 0,5mm or 1mm? Thanks.

Edit: Never mind, just ordered Arctic Cooling 0.5 mm pad.
[G3 General] :
How long does Gps take to lock? Immediately or still over a minute?
[G3 General] V1P3R_BR4Z1L14N:
GPS lock still takes a while, but after doing an AGPS wipe it's on the same speed as it was before the mod, my house and work have always been areas where the gps is bad so I'm not that good a reference.

When i get on the road with the phone again i'll be able to tell it better, but for now it's getting a lock versus not getting one at all so... it's still a win ;)
[G3 General] motoralbi:
Hello guys. I did the mod yesterday but I noticed a strange thing: a red sticker on the CPU

Probably that's because my mainboard is refurbished(changed from LG once).

Did you remove it?

Alternative Solution to Overheat

Hey Everyone!!!

I made a Guide to Fix/Prevent Overheat on the SoC, using Alluminum Foil rather than a Thermal Pad (Thermal Pads generaly overheat PCs NB/GPUs)

I brought 2 LG G3 to make and compare them with Alluminum Foil vs. Thermal Pad: The Alluminum cool more the CPU and make pressure when the SoC is failing...

[G3 General] Kulu212:
Does anyone know if the thermal mod will help with the bootloop problem?
[G3 General] AlwaysLucky:
Ummm, only if your bootloop problem is heat related :rolleyes:

A thermal pad on the SoC benefits the overall function of the phone regardless of any problems you are having with the phone. The faster heat dissipation prevents the CPU from being throttled down as quickly; or in some cases, at all.

---------- Post added at 10:03 AM ---------- Previous post was at 10:00 AM ----------

I made a quick guide with links in another thread, so I thought I'd post that here too:

To start you will need a kit like this if you don't have one already. They are handy to have anyways because a kit like that can open most modern small gadgets.

Then you'll need the thermal pad. For a perfect fit, I would use a 15x15x0.5mm non-metallic pad like this. You don't have to get that one, it's just an example. You could also get a larger one with the same 0.5mm thickness, and just cut it down to 15x15mm.

Use this video to disassemble the G3. It's the best one I have found so far. Of course, you don't have to disassemble it all the way like in the video. Just enough to expose the SoC chip (the biggest and most obvious chip on the board, you can't miss it).

Things I recommend when applying the pad, but not required:

- Perform the install in a clean, static-free environment.

- Be delicate when removing the ribbon cables. The tool kit mentioned above makes this 100% easier.

- Before applying, clean both the surface of the SoC and the surface of the metal phone frame indent where the other side of the pad will make contact with alcohol or something similar.

- When reassembling, tighten all screws as much as you can without stripping them. This ensures the gps/wifi/radio contacts are good.

My GF and I have been using this thermal pad mod for over 2 years now on our LS990s with no problems. I used 6wmk pads on both. Others have reported wifi/gps reception problems, but I found this resulted from using too thick of a thermal pad (1mm thick or more), or using paste.

Hope that helps! Good luck! :cowboy:
[G3 General] motoralbi:
I'd like to say some things about that from what I've experienced on my G3.

-1mm pad is fine,I tried to pre smash it but without any kind of result, but my WiFi works fine. Can't say if GPS has got worse(it's not working so good in G3 in general).

-having a kit is a good thing but the procedure can also be done with only the little screwdriver, while the ribbon cables can be disconnected with nails(they're like LEGOs)

-the two screws that you find near the camera(they hold the camera glass and back keys),in particular the bottom one,have got really fragile "seats". So be very carefull when you put back the bottom one, the plastic thread on the phone breaks really easily(I broke it on my G3,it's not a big deal but it's broken).

[G3 General] AlwaysLucky:
I've read reports that paste/shims and aluminum foil could work too, but it costs the same to get a pad that fits perfectly...

You could even widdle down a stick from a tree and use that too, but at $7.37 USD, there really is no excuse to do it right (and easily). :cowboy:
[G3 General] HashtagFTW:
Hi, sorry for the bother but you seem to be very knowledgeable about this stuff so I just had to ask a few questions to make sure I wouldn't do something that might mess up my phone.

1. Will this mod also work on the G3 Cat.6 LTE-A version (a.k.a F460S/L/K with the 805)? As far as I know the exterior is exactly the same and I believe the interior has a similar layout as well. Here is a photo of the inside, are they any different from the normal G3? : https://imgur.com/a/JKREi

2. I currently have the choice between buying a 1mm or the 0.5mm version of a thermal pad that is the same size (the Arctic one you linked before, actually), but the 1mm is half the price of the 0.5mm in my country. Should I just go with the 1mm or stick with the 0.5mm since it apparently fits better? Thanks.
[G3 General] Taracair:
Guys, be very careful with the proper thickness of the thermal pad you want to apply. Mine pre pressed 1mm was about 0.7mm and it was still too much. I was literally sculpting the pad and moulding it with my fingers to get the right thickness. In result I have no more issues with WiFi or GPS.
[G3 General] AlwaysLucky:
First, it's never a bother! :) That's why these forums are here! Welcome! Sorry for the delay in response.

1. As long as the inside frame is metal, and not plastic. I've read that a certain model of the G3 has a plastic-type material for the internal frame, instead of metal. But apparently this model is rare. From the look of your photo, you have a metallic internal frame.

2. Get 0.5mm if you can afford it, but be sure to Google extensively because sometimes other sites will have it for much cheaper. You can use a 1mm pad, just simply "pre-press" it to a thinner size. To do this, before taking off the protective plastic on both sides of the pad, use anything that's flat like a mirror or the bottom of a drinking glass to press it to about half it's thickness. When you do this, however, the pad will expand slightly so you may have to cut it back down to 15x15mm. It doesn't have to be exactly 0.5mm thick, and be sure to not over-press it either. When installing it into the G3, you should feel a very slight resistance, indicating the pad is contacting both the SoC and the internal frame.

I hope that helps! Good luck!
[G3 General] HashtagFTW:
Hi, it's me again. I really wanted to avoid bothering you again with dumb questions for a variant that you're not even familiar with, but me being the dumbass that I am just HAD to forget to do a disassembly for a compatibility check BEFORE ordering the thermal pads...

The problem is the gold "sheet" covering the side of the pcb that makes contact with the metal frame. As you probably already know, there's a gold "sheet" (I have no idea what it actually is, but since it looks like thin gold sheet made out of something metal, so I'll call it that) covering areas of the pcb surrounding the soc / ram chip. Problem is, the "gold sheet" in the model that I have (F460) unfortunately also covers the ram chip, the place that you're supposed to put the thermal pad on.

http://imgur.com/a/kTv85 (G3 Cat.6 F460)

https://imgur.com/a/qC9XZ (Original G3 D855)

So... I'm screwed, I think? Right now, the only thing holding me back from just putting the phone back together is this video : https://www.youtube.com/watch?v=YBQNl0-OT8o&ab_channel=FrancisPiché From how it looks like in the video, this guy has somehow successfully did the thermal mod on the same G3 variant (F460) that I have. While there is the possibility that the phone in the video is actually a D855 / the "original" G3, but considering that the G3 was getting Antutu scores similar to the Exynos 7420 used in the S6/Note5 (and the title of course), it seems likely that it is indeed a Snapdragon 805 with minimal throttling thanks to some sort of mod. So, in your opinion, what should I do? Just put the phone back together and not risk anything? Or do I just put the pad on top of the gold "sheet" and hope for the best? The phone is sitting right in front me as I speak, completely disassembled, ready for reassembly either way. I'll mostly likely leave it disassembled until I get a reply from either you or the creator of the video, so any sort of help would be greatly appreciated.
[G3 General] AlwaysLucky:
Oh nooo! :(

I have never seen that before, and it must be exclusive to the later models. For all intents and purposes, I would say do not use a thermal pad. It would appear that the aluminum sheet covering the SoC and PCB does not make contact with anything underneath it, so putting a thermal pad on it would do nothing. You can attempt to confirm this observation by pressing slightly on the sheet where the SoC is. If it bends at all before touching the SoC, it is not making contact. However, placing the thermal pad in the indention of the frame and letting it drain heat from the aluminum sheet in theory would not hurt anything, but it may not help either. If you try this, I would pre-smash the pad to ensure the aluminum sheet doesn't add too much thickness.

If your phone is overheating badly and you are desperate, you could try cutting a 15x15mm hole in it where the SoC is with a dremmel or something similar but I don't recommend it. I guess you could also remove the entire aluminum cover that is covering the whole PCB, but I don't recommend that either. I recommend going with a software solution; ie: a custom kernel that throttles the speeds at lower temps to avoid overheating.

I'm sorry I did not know about this model, but it's good you reported back to let any other F460 owners know that the thermal pad can not be used on this model, or to check inside the F460 first.
[G3 General] Hiyaslalabs:
Will this fix the blue screen error on my G3(D855)? Also the G3 I bought doesn't have any cover plate on the back and front of the logic board. Is that alright?

Nice video. I am very curious about these type of stuffs. My interested subject is CPU motherboard where different parts are used to assemble a PC. To make a CPU cool, a cooler is required. Thermal Paste plays a centric role between cooler and CPU. It makes the CPU run faster and Better by providing coolness.

Arctic Silver 5 is non conductive. see this http://www.arcticsilver.com/as5.htm

Not Electrically Conductive:

Arctic Silver 5 was formulated to conduct heat, not electricity.

(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.) I am thinking of using this - do you forsee any conductivity or capcitive issues ?
[G3 General] _jonte:
What about this method, using copper tape to spread out and dissipate the heat?

I know this is an old forum, but would this work for an LG V10? I'm totally new at this, so.

Thanks in advance.
[G3 General] AlwaysLucky:
I don't think so. Looking at this teardown video, it appears the V10 already has some sort of thermal pad already installed to the frame where the SoC is. Perhaps the XDA V10 Q&A forum might be a better suited location for this inquiry.
[G3 General] napsterion:
Does anyone used Arctic 5 and has problem with gps or phone signal ?

It is safe for our lg g3?
[G3 General] Taracair:
I used a thermal pad. WiFi and GPS are a little bit worse, but still it's worth a shot. With original fault CPU can unsolder at high temperatures and your phone is dead or will require some decent repair services.
[G3 General] ezantera:
Somobody removed metal and put thermal paste on opposite side of soc?
[G3 General] Marcos OC:
I did, covered most of the chip and a small blob on the frame (to fill gapps). Not the best option but it reduced the temps drastically under load.

No gps or signal problems, i think its not related whit the method but how you reassembly the phone. Obviously a big thermal pad may get in the way.

I get a lot less throttling too.
[G3 General] OtakuLi:
I removed it because I broke my screen and I have to replace a new one by myself. At the mean time, I scratch the paste a little bit, thats why I need to clean it up.

I made after i read this and watch the video...the gap is huge...i apply my thermal paste and i close the motherboard..i lift it up again and the thermal paste didn't touch the back....so i put both ways..not as much as the OP but again i thing the best way is a 1mm copper or a thermal pad...a good thermal pad or whatever its called!
[G3 General] Invicta:
just use a thermal pad, its much safer and it will eliminate the gap between the cpu and the back of the phone. Its much safer too, MX5 thermal paste as far as i remember has a little bit of conductivity

Okay now I.... I make it little bit different... Two layer copperfoil at the chip two layer copperfoil at the other side between thermal paste... The result is amazing after 5 times of antutu it looks like this
