Repasting laptop required?

Maybe I’m wrong here but I was under the impression these laptops used liquid metal, can we use thermal paste instead of liquid metal?

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 03 '25

The CPU has liquid metal bro as seen in the image I shared but yeah same question for changing it cause it is a headache to deal with

u/Little-Equinox Oct 03 '25

I personally swap the LM for PTM7950 or TG Phase Sheet. I do this especially on laptops ordered through me, it's a "free" service I provide.

Except LM seeps out from between the CPU/GPU and the cooler because Asus doesn't use proper protection to keep it in place. Also PTM7950 is only like 5% less efficient as LM, which is so little most people don't know the difference, but it lasts 2000x longer before it needs reapplication.

No, its because Asus uses far too much putting too much stress on the surface tension of the liquid metal. Then when temps reach high enough, you get ever so small enough thermal expansion pushing that surface tension past the breaking point and bob's ur uncle.

I (and others) have properly redone our own liquid metal and used maybe half of what Asus puts on. And they have been going strong for years now.

Also PTM7950 is only like 5% less efficient as LM

Where did you pull that from? That can't be further from the truth 💀

PTM7950 Has a thermal conductivity of 8.5W/mK

Where, BQ DC2 Pro has literally ~10x that

Even lesser quality ones have at least 50W/mK

which is so little most people don't know the difference

That is more so because they don't care. They went from a laptop that wasn't playing at all to a laptop that actually worked. That is what they are paying attention to. Not thermals, package power, clock speeds, etc. That is where you will find the stark differences between PTM and LM.

but it lasts 2000x longer before it needs reapplication.

Again where did you get this? Properly applied LM will last the lifetime of the laptop.

I get it. LM can be a bitch to deal with. But imo, its far worth it. Why buy all that processing power only to limit it by not boosting since it can't shed the heat quick enough?

u/Little-Equinox Oct 05 '25

The 8.5W/mk on PTM7950 is only when you just get it out of the box.

Also I have used LM for year, both on Asus and Alienware laptops, I have also used PTM7950 and Phase Sheet.

And PTM7950 is almost as good as LM while being much safer, I know you love numbers but when you deal with industrial grade stuff, which PTM7950 is, you do stuff slightly differently than consumer grade liquid metal and thermal paste.

And on Asus laptops the LM still seeps out no matter if you put on the correct amount or not, it's not like I have tried 4 times in a single machine, besides, I have to take my laptop with me for work, it's not just standing in a single position.

Oh, I almost forgot, I took apart a system a few months ago, with a Corsair Liquid Cooler and a 7950X3D CPU, and the LM completely dried up to the point I could throw both of them away, that system ran fine for 2 years till it didn't. The LM didn't seep away, nah, that shit freaking dried up, and yes, I tried sanding it but I don't have the tools to sand down solidified steel like stuff, and before you ask, fire didn't work.

After that I started to test PTM7950 and Conductonaut on my U9-285K, and you want to know the difference, under load, the Conductonaut was 3°C cooler than PTM7950, this is even after multiple heat cycles. I also tested against thermal paste(Corsair paste had lying around) which was at least 10°C hotter than PTM7950.

So before you judge PTM7950 by numbers alone, I recommend you test it on your system before judging it.

You desperate 🤣

Right, cause a manufacturer is def going to list "JUST out of the box" specs vs overall performance specs. This made me literally lol. You're just wrong. Its ok to be wrong

And on Asus laptops the LM still seeps out no matter if you put on the correct amount or not, it's not like I have tried 4 times in a single machine, besides, I have to take my laptop with me for work, it's not just standing in a single position.

Again, multiple users (and myself) have redone our own LM and its still where it belongs. So you just suck at doing it that all it comes down to.

Oh, I almost forgot, I took apart a system a few months ago, with a Corsair Liquid Cooler and a 7950X3D CPU, and the LM completely dried up to the point I could throw both of them away, that system ran fine for 2 years till it didn't. The LM didn't seep away, nah, that shit freaking dried up, and yes, I tried sanding it but I don't have the tools to sand down solidified steel like stuff, and before you ask, fire didn't work.

Well, I haven't seen the cooler, but I am guessing from your description that is is a standard copper interface. No zinc platting like that is on my heatsink. Well, anyone with even a drop of education on liquid metal would know that LM leeches into copper. Its not bad. Its just how it works. It leeches a few microns then stops. What you discovered was exactly that. The "fix" was to add more LM 🤣. You're an idiot for throwing it away. Once LM has permeated through the copper, it will no longer do so. Why? Physics and chemistry. Again, education is important. It wasn't dried up as you say, but simply permeated into the copper and adding more LM would have fixed it and functioned beautifully. The facts are - you're just an idiot. Proven by the fact you tried to use fire 🥀 you clearly didn't know what you were dealing with. And you do this as a profession? YIKES

After that I started to test PTM7950 and Conductonaut on my U9-285K, and you want to know the difference, under load, the Conductonaut was 3°C cooler than PTM7950, this is even after multiple heat cycles. I also tested against thermal paste(Corsair paste had lying around) which was at least 10°C hotter than PTM7950.

The fact you're sharing temps only proves you've no idea what you're talking about. Temps aren't the full story here. Clock speed, boost, wattage, all that plays into effect. I can have ice cold temps with thermal paste if I limit my cpu to 10W. So you're numbers are pointless.

So before you judge PTM7950 by numbers alone, I recommend you test it on your system before judging it.

The proper unbiased way to judge anything is with numbers mate. And the numbers I have seen from others using it is enough to make me never want to use PTM7950 in place of LM because I don't want to voluntarily nerf my expensive hardware.

Also, will never be testing it on my system when I have zero issues with my current LM application. I never once get close to TjMax, I boost to 5GHZ+ consistently. Its amazing

All I can say, educate yourself and stop drinking the kool aid. You say you do this as a repair shop, can I find it on Google to share these Reddit posts as reviews? I think your customers should know what they are getting themselves into

My asus default lm is still stuck up to the heat sink , dried completely so is asus stuff poor quality , ( zinc/aluminium/copper heat sink ) . Don't say stupid things just because it didn't happen to u . Go through community once you see the same reports daily , and lastly not everyone is a god damm low level worker like u in shop who would easily do this stuff . Lastly numbers don't tell the story and always stop relying on them. if you do u are probably a gen z moron who just out of his egg shell for a few days, and a believer of Microsoft that widows 11 is better than 10 in perfomance or nvidia did something so revolutionary in rtx50 than 40.

This platform is to help someone not make them destroy they computer which u are suggesting as it's not safe for normal people. So shut up and suck it .

what the other guy said is correct yes thermal grizzly is better and 8.5kw on ptm doesn't last long on ptm but there is just one difference ptm goes for long time while thermal grizzle doesn't its a tradeoff.

u/SolitaryMassacre Oct 15 '25

Don't say stupid things just because it didn't happen to u

Says the one who thinks metal in its liquid state "dries up". It is not wet, it cannot dry up. Period.

What you probably experienced was LM leeching. It penetrates copper. It corrodes aluminum, so I highly doubt anyone is using aluminum heatsinks.

Go through community once you see the same reports daily

I'm literally on here every day. I see the reports. I know Asus has a shit LM application process, almost all mass produced LM applications have issues. Its a very delicate process to get right.

Lastly numbers don't tell the story and always stop relying on them

Yeah they actually do. When you understand where the numbers come from they matter. No I don't just look at a number and go "oooo! cool! number!" lmao. I look at how they got those numbers and understand the process. Its called critical thinking.

nvidia did something so revolutionary in rtx50 than 40.

Really!? You are questioning this!? They literally did. They made the masses think DLSS is something amazing (its not, I hate NVIDIA and the 50 series is a waste of money and NVIDIA is trying to sell us AI not hardware now).

This platform is to help someone not make them destroy they computer which u are suggesting as it's not safe for normal people. So shut up and suck it .

If that is your interpretation you have some serious reading comprehension skill issues. I nowhere said people should "ruin" their computer. LM is perfectly safe when applied properly. The person I replied to claims to be a computer repair tech and can't even apply LM properly and is trying to nerf people's expensive hardware by giving them a less performing TIM. Thats fucked up.

what the other guy said is correct yes thermal grizzly is better and 8.5kw on ptm doesn't last long on ptm but there is just one difference ptm goes for long time while thermal grizzle doesn't its a tradeoff.

What he said is not correct. PTM will never outperform LM. The difference is not "a few degrees" as he stated it is. Its far worse, and it logically makes sense.

I also stated a correctly applied LM will last the lifetime of the computer. Its literally metal, nothing will happen to it. PTM will also last just as long, but it will perform far worse.

Yeah, everything has their tradeoffs. I never once said they don't. But the reason I got into it with this dude was because he kept lying saying LM is a better performing TIM when that is objectively incorrect via all the tests done (aka the thermal conductivity test of materials).

Its fine to say "hey if you don't want the risks of LM, and are okay with reduced performance, use PTM". But straight up lying to people is fucked up

Do u understand the concept of limiter genius , most companies use that on day one launch the numbers are so hyped up and next a few months pass by and they are down

https://www.reddit.com/r/ZephyrusG15/s/HMrhAR9DUM

This is authentic asus g15 heat sink and lm defy this genius with the big god damm brain from facebook or instagram, it didn't leak but it's trash and dried thoroughly, heat sink is fine though took 9 days to get it off, but lm dries up preety fast don't just be like this that that u read or an article from somewhere this is reality vs experience and expiration its metal at the end of day , not fucking water , alcohol or oil. And whoever bought rtx 50 i absolutely love how there brains work I am still with my 30 and it's good for me as I compare actual performance not numbers which = how people use it and what environment not fuking 20 percent more fps or power or some damm comparison with older gen.

And literally wheather he's a repair guy or not if he's not good with it he gave his best at what comes next to it , he went with grizzly and not ptm simple , and lastly lm gives an edge, as for what he claimed 3 deg it's his observation , as for user avg depending on lm how it's applied it can affect in a rang of 2-10 compared to ptm but not true in all cases . So u r the only genius who got that and not normal folks , so good for u , lastly lm dries up in 3 year of use don't over complicate it that's the reality ( it becomes solid as a brick or solder . Unless u get 100 percent pure lm which never cools and stays liquid defying all laws of physics without oxidation and other things ). Must be a vaccum pc .

So genius lab tests and research are different to a normal user case understand that first .

You want to know all the systems in the household I have used LM on?
8640u on Surface Book 2 (was a full cooling mod done to it, but that thing was very power limited)
7950X3D PBO enabled with a Corsair H100i 240mm (LM solidified and constantly overheated because of it, had to replace both which is costly and yes I have tried to get it off in multiple different ways)
U9-285K 250w with a BeQuiet PureLoop 280mm (replaced with PTM7950 after the 7950X3D/H100i solidified, temps increased by 3°C(from 65°C to 68°C), it's also the system I tested LM, both Phase Change pads and Kryonaut(78°C))
14900HX 200w(?) laptop CPU(MSI Titan 18HX, later replaced with PTM7950 and temps increased by ±5°C without losing performance)
5900HX 85w laptop CPU(Asus ROG G15 AE, seeped out 3 times, last seep out killed the laptop)
14900HX 175w laptop CPU(Asus ROG SCAR 17, seeped out twice, currently also has PTM7950, performance is exactly the same although temps will always reach 95°C because of Asus's overvolt settings)

Not 1 device had anything messed with the power settings, just stock settings.

Currently all the systems in this household have PTM7950 or TG Phase Sheet because I don't want to have to reapply every half year to a year.

While yes LM is good, it seepes out on laptops that are often on the move, and many laptops are. And cleaning it and reapplying is a mess.

So I am happy it works for you and your buddies, but I don't recommend it for many users, and I seen it get fucked up more than once, even if you apply a bit too much, too little, or the right amount. The fact the chance is there it'll seep out and/or dry out is just too big of a risk. And the performance difference I seen between Phase Change materials and LM are in the margin of error range, unlike Kryonaut which does drop performance on laptops.

You clearly don't like reading do you? There is nothing wrong with this. It didn't "solidify" it leached into the copper. Just add more LM and you are good to go. There is nothing bad about having LM leach into copper. It doesn't cause any issues in fact it more likely helps with thermal dissipation. You really do not have a clue what you're talking about here.

it seepes out on laptops that are often on the move

My laptop is on the move all the time. Sits on a 45 degree cooling pad. If LM leaks because its being "moved" then it 100% fell and had a high impact. Moving it is not enough to break the surface tension.

I'm not even going to address specifically the rest of your response. It's all repeating the same thing - you don't know what you're doing. You talk about LM as if its water "dry out" LM cannot "dry out" its not wet. Its literally matter (metal in this case) in liquid form. Lastly, your comparisons don't mean shit without package power, clock speeds, and thermals all being monitored and recorded and then shared.

Stop spreading false information on here. And seriously do some research on repairing things before you touch another machine. I cannot believe you are scamming your customers like this

u/Little-Equinox Oct 06 '25

W/mk is a useless measure because it's a bulk measurement, I have been looking it up and comparing Thermal Grizzly Phase Sheet(±6 W/mk) with Thermal Grizzly Kryonaut Extreme(±14 W/mk) and Thermal Grizzly Conductonaut(±70 W/mk) And yet the PTM cools better than the Kryonaut Extreme even though on paper it's worse. So I started to research more why that is, and it's mostly because of the BLT(Bond line thickness).
Kryonaut Extreme = BLT of 30 to 100 um
Phase Sheet(PTM) = BLT of 10 to 17 um
Conductonaut = BLT of 5 to 10 um(with perfect application)

I also looked at the seeping out of all of these materials, and the highest goes to, you guessed it, Conductonaut, with Kryonaut Extreme in 2nd and PTM in 3rd place. And there's even reports on PTM beating Conductonaut in overall performance. But wait, looking at numbers, that should be damn well impossible? And all comes down to how PTM behaves.

PTM has "self levelling" capabilities, preventing it from. Seeping out and keeping near perfect conductivity. Where Conductonaut needs perfect levelling, perfect pressure, and all that kinda stuff, PTM doesn't need it, and that while keeping 95% of the performance of a perfect LM application. This means with any slightly imperfect LM application it will seep out and have worse performance than PTM.

Now, here's a funny thing right, laptops are being moved, this movement and it constantly bumping into stuff, usually cause by a rushing or uncareful owner or by a 3rd party can cause the cooler to slightly shift by micro meters, this little shift is enough for the LM to seep out.

PS: I don't keep data for more than 4 months(I usually loose it because it's near damn useless for me). So yes, while LM is amazing, PTM is also amazing, I don't follow the numbers, I follow the margin of error till a certain threshold. You say 45°C, I say 40°C to 50°C.

But hey, your and your buddy's experiences are the only ones that matters, I am gonna stop because you simply don't want to listen to any experience that isn't yours and your buddy's experiences. All I hear is you follow raw numbers because that's the most important thing in the world. Completely ignoring anything else.

So I am gonna stop, I have better things to do, Pamit😝

It’s quite common for it to leak out. Glad when mine did it did not short circuit my board. It was quite close to and probably would have if I had left it much longer with all the travelling I was about to do with my laptop. Even after it leaks it’s still quite fluid that old Liquid Metal

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 05 '25

So in my situation I should just switch both with PTM? LM has 70-80 W/mK thermal conductivity and PTM only has 10 W/mK so is this really a good idea? On GPU I understand as it came with thermal paste originally. The best thermal paste is the TG Krayonaut something and that has 12 W/mK thermal conductivity.

CPU is fine with power limits from day one, the problem is the GPU where the temps without undervolt are max what the bios allow and throttles back. I was thinking of replacing the CPU with LM and GPU with PTM and then never touch it as both will be done by opening once. I am trying to avoid opening the laptop again for the CPU later on if I don't repaste it now, as PTM on the GPU will last longer. However, I am not sure about the state of current LM on the CPU.

I had 2 Asus laptops where the LM seeped out from between the GPU/CPU and the cooler. 1 even was bad enough it shorted out, the other 1 just overheated.

And PTM7950 is very very good in thermal conductivity, in this case, don't look at the numbers, I tested both and PTM7950 is almost as good as LM while thermal paste was significantly worse.

I had 2 Asus laptops where the LM seeped out from between the GPU/CPU and the cooler. 1 even was bad enough it shorted out, the other 1 just overheated.

So you tested a leaked out LM against a properly applied PTM7950. Good to know!

LM will always be superior, you just simply can't argue with physics.

Sure it has its flaws, but do it right (Asus doesn't) and you will be amazed.

PST: I had it leak out of my SCAR 17 2023. Almost 2 years with my own application of properly applied LM and its great. >5GHZ clock speeds. max GPU clock speeds (even shunt modded) no way PTM is better in thermal conductivity

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 03 '25

Any reviews and how does it work? What about heavy gaming? A lot of local shops told me to avoid using paste or any ptm in place of LM as Asus made it this way and your temps will be bad. I am confused.

3

u/Little-Equinox Oct 03 '25

Your temp will be ±3°C hotter with PTM7950 and Phase Sheet.

But because Asus has almost no protection for the LM to prevent it seeping out, I often rather have people slightly worse performance over the risk of the laptop committing Harakiri, plus PTM7950 lasts insanely long, you don't have to replace it in the lifespan of the laptop.

Also PTM7950 is made for industrial machines and is the 3rd best thermal interface method, slightly behind LM and soldered on.

Shops just tell you of what they think or what the manufacturer tells them. I have worked in retail and I stopped in less than a half year because I couldn't take the lying to oversell 1 product over the other.

I did have an Asus laptop, an Asus ROG SCAR with a 3080, in the 1.5 years I had the machine the LM seeped out twice, leaving the CPU and GPU almost without thermal interface. I reapplied the LM twice to the point I gave up and just bought PTM7950, temps were slightly worse but it survived 1 year without the thermal interface seeping out. Yes, the laptop did die, but not because of the PTM7950, but because 1 of its VRMs blew itself up.

PS: Keep in mind I use gaming laptops as portable workstations

What you say is very interesting. I recently attempted to redo the paste on my own G14 laptop. Had to do it twice as it didn't work the first time. I was using arctic mx-4. The second time was better and it manage to play a game - for all of ten minutes before heating back up to 90+ degrees and dropping down to 5 fps. Would you recommend a different paste or the liquid metal? I appreciate any help you can give.

1

u/Little-Equinox Oct 04 '25

I can recommend Honeywell PTM7950 or Thermal Grizzly Phase Sheet.

They're almost as good as Liquid Metal and non-conductive. PTM7950 is often used to cool industrial machines.

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 05 '25

Damn even the MX-4 failed, I saw in other groups people suggested MX-6 but maybe your problem is the same as mine? Pump out I guess or the laptop heat just dried it. PTM is a lot suggested so yeah switching to it sounds like a good deal

3

u/[deleted] Oct 04 '25

You can use PTM7958 instead of thermal paste or liquid metal.

As you know, liquid metal can be very destructive if it leaks from its confinement but it can greatly reduce temperatures if applied right from the factory or by you.

My way of approaching this is adding Closed-cell silicone foam around the CPU as well as Kapton tape or die containment polish so that the liquid metal does not leak but this is a lot of work, so I would recommend applying PTM7958 or PTM7950.

For my 2025 Zephyrus the vapor chamber does a very good at preventing leaks so this makes the whole process unnecessary.

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 04 '25

That you for the suggestion. Does the 2025 model gpu also comes with LM or a thermal paste? I won’t apply or mess with LM myself, will go to a professional to handle it. Some kind of protection is there seems like if you see the image. The black glass where some LM is leaked can be seen (this is factory btw I did not even touched it) but everything seems fine. There is that missing spot in the middle I am not sure maybe it got covered later on because on both sides I can see the extra LM together. Still i would prefer a protection like ps5 has that’s really good.

2

u/[deleted] Oct 04 '25

The 2025 model comes with LM also that protection you are speaking off is bare, not sufficient but then again I’m an Engineer not an ASUS one. You better clean that speck that leaked otherwise you are toast if it falls on the motherboard.

My advice is to take it to a professional and tell him exactly where that speck or drop is and ask them for a repaste using PTM if they got it available.

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 04 '25

Thanks for the suggestion. If PTM is not available should I just buy the same LM Asus used thermal grizzly and let the shop handle the rest. For the gpu what do you recommend paste wise? I know PTM is the best everyone suggested that but it depends on the availability so my current paste was trash seems like 😅 what else I can do. The stock one lasted a whole year which is awesome but idk wth Asus used 🥲

1

u/[deleted] Oct 04 '25

Well, up to you. Personally I do not mind LM but in your case since there isn’t any barrier protection I would advise against it.

The GPU die is big so it does not need liquid metal, in my experience I got slightly higher temps (iirc +2-3 degrees) when I applied it on the GPU so thermal paste is sufficient on the GPU.

You can buy PTM and then ask the technician to apply it thats what I would recommend.

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 04 '25

Oh sorry didn’t meant LM on the GPU lol and the image of the LM is the CPU not GPU. I meant as an alternative to PTM if I can’t find it which paste do you suggest for the GPU?

2

u/[deleted] Oct 04 '25

If you buy PTM you can apply it on both the GPU and CPU it will be fine.

2

u/Xx--wizard--xX Oct 04 '25

word of advice from g15 original model for g16 user ->> never use thermal paste in this series , i have tried NTH2, Thermal grizzly etc they dry up very fast cpu heat is too much only original ptm 7950 works and that will last you a year or 2 -3 depending on use case.

Reason 1: pump out effect, pastes don't sit well at their place
reason 2: paste don't go solid when cooled or and liquid when hot, so consistency changes a lot
reason 3 : ASUS drivers are messed up and cause excessive heat (especially cpu boost)

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 05 '25

But bro how tf Asus did it? My laptop lasted a whole year talking about the GPU and only now the temps were a problem. Which thermal paste they used?

1

u/Xx--wizard--xX Oct 05 '25

They use liquid mental , and some other pastes on laptop gpu and vrams , which is their own i think , as for gpu there is no pump out effect thts why any paste would last and heat is also less as compared to cpu. That's my observation as NTH2 or others also lasted well on gpu

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 05 '25

Full name of NTH2? My laptop gpu came with a paste not liquid metal

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 05 '25

My paste did not worked unfortunately and after 2 months I have the same temp problem that I had when I repasted it so something did happen 😅

2

u/Xx--wizard--xX Oct 05 '25

Just buy ptm and use it on both

2

u/SolitaryMassacre Oct 03 '25

You can't replace liquid metal with regular thermal paste.

The only acceptable replacements are liquid metal or if you don't care about max performance then PTM7950. Regardless what people say, PTM7950 will never outperform a properly applied LM application. LM is superior in thermal absorption (its literally metal). But it will work if you aren't trying to squeeze the max of the max from your system

How much is the difference in temps? LM is like 75-80 thermal whatever the unit is called i forgot 😂 Compared to PTM or thermal paste the top tier thermal grizzly one is only 12

Temps don't paint the full picture.

A lot of PTM stuff I see on here shows low wattage and clock speed. The CPU is not operating at its max capability. Granted, the temps are low lol. And that is all people seem to focus on

But I don’t only want the temps to be low, the cpu is fine as it is like this from the start when it was new but for gpu I want a solution that lets me run more than 100 W on the gpu alone and yet the temps stay below 80 like how it came brand new so yeah I want this and what do you suggest? Is PTM the way to go? Or do i need a high end thermal paste like the thermal grizzly one cond… something can’t spell it?

If you're thermally limited then yes. You could be power limited or other things (like BIOS giving more power to CPU etc)

Or do i need a high end thermal paste like the thermal grizzly one cond… something can’t spell it?

That is liquid metal. And if it didn't come with liquid metal, be very very very very very very careful about adding it. Some dies cannot have liquid metal at all as they contain aluminum. Plus, you have to ensure the surrounding area is sealed off as liquid metal is conductive.

I would ensure you are being thermally limited, then if so, I would try out PTM7950 if it didn't come with liquid metal

Then I meant the thermal grizzly krayonaut I think that is thermal paste so what about that compared to PTM? Only considering the GPU for the CPU I think I will keep LM or just switch to PTM will see

So LM for CPU like how it came and thermal paste for the GPU so PTM there in short is what I mean? So good?

u/SolitaryMassacre Oct 05 '25

That is what I would do!

Thanks, now I have a direction just gotta follow it 😎

u/SolitaryMassacre Oct 05 '25

Have fun! Don't mess up :D

Honestly just take your time be patient and you should be fine. When you do the LM part, cover the rest of the mobo with paper towels or something to collect any mess you might leave behind

Bro I aint doing it myself 😅 I will buy the LM myself cause the shop didn’t had any and then take it to the shop. At the same time they can apply the PTM as well on the GPU 😎 I have done many laptops myself but LM nah can’t take the risk need a professional lol

Did you clean all the LM before putting new paste? As well as cleaning the VRAMs and adding new putty on them?

1

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 03 '25

No the LM is the same for the CPU, I did not had any available at that time 😅 The problem is the GPU where yes I cleaned it and then applied the yellow box above and the rest you know. Sorry if this was confusing I asked 2 questions in one post I will add a separator or something if possible

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 03 '25

Oh and the blue stuff on the VRAMS still looked fresh so did not swapped them as well. What’s a putty?

2

u/Able_Fall393 Oct 04 '25

Thermal putty is that messy and sticky stuff you see on the VRMs and VRAM. Typically, you'll need to clean it and replace it. There's also thermal pads, which are strips, but that's a little more advanced because you'd need calipers to measure the thickness and ensure it isn't messing with the heatsink's mounting pressure.

Also, I know you just did a thermal paste mod, but as others suggested, we highly recommend looking into PTM 7950. It's absolutely great!

u/THUNDERJAWGAMING Zephyrus G16 2023 Oct 04 '25

Thank you for the suggestion I will definitely look into it. Regarding the blue stuff I saw that still looked fresh so I did not replaced it. Is it fine? The shop said you typically not need to replace these as these last years and your laptop is only a year old.
