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.

@@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.

@@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.
@ntd2524 ай бұрын
@@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.

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.
@ntd2523 ай бұрын
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.

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.
@ntd25216 күн бұрын
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.

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.

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
@ntd252Ай бұрын
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.
@ntd252Ай бұрын
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).

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.

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.

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.
