Laptop thermal paste

chassis wrote i was told that the best thing to do is replacing the stock thermal paste
do you guys know a shop or anyone who offers this service ?

I would try to do it myself.

First I recommend you start to research how to disassemble your laptop, then where to get good thermal paste (maybe someone can lend you some).

Also maybe the thermal paste that is inside is already good, in which case it's better to leave it as it is. So do some research about that too before you change the thermal paste. Since this is a gaming laptop, I suspect that they have already put in good thermal paste.

There are few things that can go wrong when disassembling a laptop. Mostly:
- Be very careful with the LCD (never bend it or put pressure on it even a little)
- Do not force anything or over-tighten anything. Use the correct screwdrivers.
- Watch out for the little connectors (easy to forget one and then you have to disassemble the whole laptop again)
- Thermal paste is messy, make sure you apply it uniformly (using a plastic card) and just the right amount. Try not to smear it all over the rest of your laptop
- Finally write down where every screw goes, so that you don't put them in the wrong place

As for a shop I trust to do this better then myself, I don't know any.

PS: I did a quick search on google and it seems your laptop has a removable bottom plate for easy access, so that's good news. However judging from the picture it looks like you will need to re-apply thermal paste for the GPU as well

DNA wrotethermal paste will not solve anything, the heat capacity of the cooler is lower than the dissipation of the gpu and cpu working together.
better thermal paste will get you couple degrees at best. if it did anything at all, if the fan is blowing very very hot air then the thermal paste isnt the issue

CPU and GPU are often not working together at full throttle. In those cases, the laptop would throttle both to keep heat output manageable. In cases where either is running at full throttle or both are running but not at max, thermal paste should help.

Also, if the cooler weren't able to handle the load he's testing, temperatures would keep going up until the laptop overheats and shuts down. A stable high temperature indicates that the cooler is able to keep up with the load presented.

thats not correct if what you said is right why is then beefy desktop coolers keep higher tdp cpu and gpus at 70degrees at full load? simply because the coolers have higher heat capacity laptop coolers have very low heat capacity and surface area and rely mainly on the fans to dissipate the heat fast this is why you stay at higher temps

what you said about cooler is able to keep up is right, but when you have a piece of metal thats already at 60 70 degrees its heat conductivity is even lower so the cpu or gpu will stay at higher temps

if the load he is testing is taxing both cpu and gpu and the fans are blowing very hot air thermal paste won't help

You're confusing several factors here.

Desktop CPUs and GPUs have higher TDPs and the coolers used have a high heat capacity. The TDP for each component is well below the TDP each respective cooler is designed for.

Laptop CPUs and GPUs have lower TDPs and the coolers used also have a lower heat capacity. However, they do not necessarily have a heat capacity low enough as to be lower than the combined TDP of both components. Furthermore, laptops often employ aggressive cooling in the uncommon case that both CPU and GPU are saturated AND each hitting its max TDP. This helps keep overall heat dissipation below the heat capacity of the cooler.

Laptop coolers with lower heat capacity that what both the CPU and GPU are putting out are coolers that simply cannot keep the temperatures stable. Both components are pumping out more heat than the cooler can dissipate and temperatures keep rising, leading to overheating. This situation almost never happens with modern hardware as the laptop simply throttles frequencies and voltages and increases fan speed until this is no longer the case. A point of distinction between laptops is how high they can sustain their clock frequencies in the worst possible scenario, which is both components being at full load and hitting their respective TDPs. Even in a compute workload, this almost never happens as generally, one component bottlenecks the other - unless you have separate workloads, one pushing the CPU and another pushing the GPU to the max without bottlenecks happening (i.e. without the GPU requiring the CPU to feed it in the meantime).

what you said about cooler is able to keep up is right, but when you have a piece of metal thats already at 60 70 degrees its heat conductivity is even lower so the cpu or gpu will stay at higher temps

It's not that simple. The regression depends on the heatsink fluid used in the heatpipes.

if the load he is testing is taxing both cpu and gpu and the fans are blowing very hot air thermal paste won't help

He didn't state he's stressing both at the same time so I did not assume that he is. In all cases, thermal paste will help, even if in a limited fashion, since it increases thermal conductivity. Given the cooler is already keeping temperatures stable (but high), then its heat capacity is beyond what is being dissipated and therefore the bottleneck is not heat capacity, but thermal conductivity.

man u can believe whatever u like i am talking simple physics here u are talking about irrelevant stuff just my 2 cents

ok chassis apply thermal paste and tell us if it lowers ur temps drastically since u already have a more than capable cooler

Still the same exact personality. You have not changed a single bit in all these years. Great to know you're consistent at least LOL

The simple physics you speak of are this: a heat capacity lower than what is being dissipated means that more heat is produced than is released into the air. This heat stays on-chip, and given the chip is simply releasing more heat, this will lead to overheating.

The simple rule is: if your temperature remains stable, then the heat being produced is equal to the heat being released and you have equilibrium. Using a cooler with higher thermal conductivity or heat capacity will simply shift that equilibrium towards a lower temperature.

These simple physics are the same physics that explain why in a water loop, regardless of pump, radiator, and component order, components usually reach the same temperatures once the water loop reaches equilibrium and that any differences are due to differences in pressure or the form of water flow e.g. jet.

It's not about beliefs and frankly it's ugly that you choose to end a discussion like this. It clearly indicates you have either run out of arguments or you're explicitly disrespecting the party you are engaging with.

Whether chassis gets lower temperatures or not is up for tests, since the thermal paste might already be good enough.

But, repeating, this is not related to the assertion that the laptop cooler's heat capacity is LOWER than the combined TDP of both CPU and GPU, nor is it relevant, since laptops don't insist on keeping both CPU and GPU at their highest frequencies like desktops (used to do) when both are maxed out.

Do note that liquid metal is tricky to apply as well as risky. Furthermore, the liquid metal leeches into the copper and gives you poor results if you change it out for regular thermal paste. You'd need to sand the surface and this is of particular worry on what is probably already a thin piece of copper making contact with little thickness and clearance.

Make sure you read up before you use such a compound.

Honestly I don't care anymore about you and and your laptop and your money so count me out.
I was trying to help but it seems you have already decided what the solution is, so I'm not sure why you are wasting our time.
To answer your original question, any computer shop will replace your thermal compound.
And to answer your second question, yes $70 is expensive because it's like a 1/2 hour to 1 hour job.
Good luck.

I got some MX-4 if you want

chassis wrotehey, thanks for the reply

i honestly don't think i can reapply the thermal paste alone ( i don't want to mess anything up ) if any of you guys is willing to help that would be great : )

i already found a guy (Tarek from the ROG facebook page)

he says he will do it for $70 is that too expensive ?

Just my two cent, stay away from the ROG / Tarek guy. we had a discussion about him a few years ago on the forum, long story short : He has nothing official, he does not provide warranty and he his over expensive regarding everything he sells and does, finally if something goes wrong he will blame you and refuse to take responsibility

working with the guy is like playing an expensive russian roulette

I have a GL502VS, changing thermal paste helped, a little. Don't expect drastic changes. ( Only 5c or so under load).
What really helped is undervolting. I undervolted both my 6700HQ and 1070.
I have 6700HQ on -150mv and 1070 running on 1730mhz 0.800V.
So all in all, undervolting and changing thermal paste (GC-Extreme), now I max out at 70GPU, 75 CPU under full load (90%+ CPU, 98% GPU).

Also, don't get near liquid metal. If you do anything wrong, your laptop is as good as dead.
