Zephyrus G14 2022 Teardown and Repaste

[@zerotwo_.002]

28:10 glad to see others also have this same issue of it slightly sparking. I guess whenever i do this i will have drain the battery to 0. Or hey it's not like its gonna get damaged as long as you keep the clips safe . Good video!

[@ntd252]

I think so. The electrical spark is popular in electronic devices, which can be explained by Faraday’s law of induced current if you're curious. Some people reported it would brick the laptop, but I think there was something else in those cases.

[@zerotwo_.002]

@@ntd252 yeah the report of people bricking their laptop is to do with them breaking the metal retention mechanism of the battery connector holder. Yeah law of induced current should explain it but it could have been reduced or eliminated if they made the connector to be more recessed. Like on their vivobook series they use another connector which doesn't have the same issue

[@ntd252]

@@zerotwo_.002 I agree with you about the battery connector. This one is challenging to handle and non-intuitive.

[@Eng586]

​@@ntd252 Pretty sure it just sparks because of the laptop recharging the capacitors. Faraday's Law of Induced Current deals specifically with the induction of electromotive force (EMF) due to a changing magnetic flux through a loop of wire. It's not Faraday's Law because the spark is not caused by a changing magnetic field inducing current.

[@ntd252]

@@Eng586 Yes, It could be the capacitors, but I lean towards the induced current, because there's actually a changing magnetic field in coil elements. But I was wrong about Faraday's law. It should be Lenz's law (" polarity of induced emf is such that it tends to produce a current which opposes the change in magnetic flux that produced it"). By connecting the battery, there's an input current going in the coils and the magnetic field of coils changes from 0 to some values, hence EMF polarity and its current kind of oppose the input current.

Love this video thank you

Glad it helps!

[@axelcaldera4700]

I am thinking of doing the same procedure, did you see any improvements in the performance of the thermals in the laptop? Mine has already 2 years and it shut downs due to thermals while playing games like overwatch which is not that high demanding.

[@ntd252]

My laptop temperature really improved noticeably, can run without fan for some use cases, because its liquid metal had spilled badly like in the picture at 10:56. I believe yours will improve as well, because it's not supposed to reach the temp that causes unexpected shutdown. Besides, 2 years is long enough to do a big maintenance.

[@xbriskx]

CPU is maxing out at 96 as it did before. GPU is like 93 degree. Feels warmer than before, what did I do wrong? Too much of the thermal putty? It's a bit hard to mess up putting on the PTM7950? Does it matter if the square was a little bit over the silver central part? I had G helper set to 'agressive' for boost instead of enabled I realise. Everything else should be stock. Changed it to enabled, close throne and liberty and temps coming right down again. Surfing the web my cpu is showing 60-70 and gpu around 60. Just opened wow classic and PC seems quieter, CPU is only bouncing around 80 degrees and GPU 70 degrees. Everything seems ok? The one thing I'm noticing is that the fans are all over the place, one second they are loud, onetime they are silent etc, not sure what I could tweak to make them ab it more stable. I find it a bit irritating.

[@ntd252]

The piece of PTM7950 can be bigger than the CPU die's size. I think you already did a good job. You can try resetting your BIOS and then setup G-helper again with Balanced mode and default fan profile. Tweaking the power limit and undervolt number is also fun as well.

[@seiswibowo]

Quick question, the part you are cleaning at 16:10 and 18:05 , the part covered in liquid metal in the vapor chamber, is it made of copper or nickel? Thanks

[@ntd252]

I believe that rectangular part is made of nickel or something that is absolutely not copper.

[@poteattoast5164]

Quick question, should i put the PTM7950 inside a fridge before applying it ? I heard some people said that it makes the installation much more easier because the pad become solid

[@ntd252]

You really should, that's one of the thing I mentioned in the video. When applying it, you should press firmly the pad into the CPU, so it can stick on the CPU die surface. It would make the process easier, because after that, you need to take out the thin film from the pad, which might be handy.

[@poteattoast5164]

​@@ntd252Oh sorry, i didnt read that part 😅, thanks for replying mate. How's the performance by the way after 3 months?

[@ntd252]

It's actually 5 months since the recorded time, I can say it's performing well and staying cool (not kind of cold, but casual tasks don't trigger the fan to run very much). I also combine it with IETS cooling pad for high performance tasks that uses full GPU power and CPU can stabilize at 3.7 GHz full time.

[@poteattoast5164]

​@@ntd252 glad to hear it. Mine is a little bit mess up right now. I decided to change mine with normal thermal paste without knowing it uses LM to my nearest laptop services store. Now, it always shut down whenever i open games. When i checked the temps, it was very high, like around 95-98 degrees. I might follow your video's to replace it with PTM7950.

[@syka2180]

Hey, i've noticed there's a little spark when you plugged the battery back in, is it normal to do that? anyway, love the video!

[@ntd252]

Good catch! I think it’s normal due to what is called “Faraday’s law of induced current” because electronic devices usually have coils. It happens almost anywhere when you plug device, but sometimes it’s more noticeable than others.

[@xbriskx]

Can you provide a full list of all equipment used?

[@ntd252]

A set of laptop open tool kit would be useful, and they are usually sold by a whole set. You can look for "repair opening tool kit"

[@jetzziivanovich3206]

Hi! I did the procedure with exactly the same thermal pad and thermal putty on a laptop that is around 1,5 y.o. I have dropped from around 13252 to 13000 in cinebench r23. So the question is why use silicon pads and not graphite/thermal paste/ liquid metal? I guess any of those should yield better resulta

[@ntd252]

Did you use the PTM7950 (I don't think it's called silicon pads)? This type of pad material has great thermal conductivity compared to the popular thermal paste (I think there are reviews showing it's even better than awesome thermal grizzly kryonaut in terms of temperature and longevity). Liquid metal is still the best solution if you want the lowest temp as possible, but it's more risky to use in laptop (especially when you put your laptop in vertical position) since the liquid might spill out, causing short circuit or worse performance. People tested PTM7950 vs Conductonaut and the result is impressive enough that convinces people to change to this thing.

[@ntd252]

The score might decrease right after you apply the PTM7950, because this material needs a few heating cycles to be able to transfer the heat efficiently. Maybe your liquid metal was already very well applied. I think time spy test can tell better about the thermal improvements because it uses both CPU and GPU (if you already had tested before).

[@jetzziivanovich3206]

@@ntd252 Yeah, I did use exactly Honeywell PTM7950. I'll look into the temperatures later too. Also did you apply two layers of the pad?

[@LabelFlash241]

Can you link the dissasimbly document you used? This video is very helpful

[@ntd252]

It's the upgrade guide from Asus. I've updated the link in the description.

[@amelia20fe]

hows the temp now? Hesitate to change to PTM7950 becuase AMD just heats

[@ntd252]

My machine is still doing good. AMD or intel, they all heat when you deal with high performance chips, but this AMD zen 3+ is more power efficient, means that at the same performance level, it uses less power, hence less heat. The reason people want to replace the factory liquid method with PTM7950 is because the liquid metal is often spilled over in this model, making thermal productivity bad.

[@xbriskx]

i"m so scared about the battery, can I just leave it plugged in whilst redoing the pasting?

[@asianmelonbread]

It’s highly recommended to keep the battery unplugged. If you want to be extra safe, I recommend holding the on/off button for around 15 seconds to prevent any electricity stay in the motherboard. This will make the computer take a little while to boot up tho, but it won’t harm the laptop.

[@ntd252]

@@asianmelonbread Thank you for giving that useful information

[@Addicted2cars]

32:13 you have updated the GPU drivers so the test is uneven...

[@ntd252]

Theoretically, yes, you're correct about that, comparison should have been on the same version.

[@MmMchannel154]

what causes this g14 liquid metal leaked?. I was always worried about my G14, because I always use a laptop stand that was quite tilted, could it leak the liquid metal. i wish u answer my question😃

[@ntd252]

I hear this quite often from the community that there might be something with Asus's manufacturing process. It's less likely that the liquid can leak out to the surrounding circuit because there's already a small piece of foam preventing it. However, it seems the application process in the factory might be badly configured which probably leads to what we see in my video.

damn that factory liquid metal application is so bad. You can clearly see on both cpu and gpu..

If you're in zephyrusg14 subreddit, you will be surprised by how common it happens. From technical standpoint, I think I can't blame everything on Asus, because the application of liquid metal process might be very challenging on mass production, and the QA process also suffers from it.

Is that a normal thermal paste? Is it better than liquid metal?

[@ntd252]

Hi. It’s the PTM7950, a highly thermally conductive material, far superior than common thermal paste, but not as conductive as liquid metal. However, a lot of benchmarks have shown PTM7950’s performance is almost on par with liquid metal, about 8/10 I would say, and much safer because it’s not electrically conductive. I replaced liquid metal with PTM7950 for that reason, and for the fact that liquid metal was applied very badly on my machine as you can see in my video.

[@derekhatake]

How much u6 did you use 20g or 50g?
