It's been about 3 years and my temps have gotten worse compared to when I originally got this G18 Strix 4080 laptop (easily hitting 100c with an undervolt). Since its already geared for LM TIM, I'd just going to replace/repaste it and at this time not interested in switching to PTM. Even brand new, this laptop ran hot (upper 90s CPU temp consistently under load, even undervolted), so losing even a few degrees of performance would matter.
I'm aware liquid metal is the TIM used on this machine. I know the CPU for a fact, not positive if the GPU uses it too but I imagine so.
I've handled liquid metal before, many years ago when using it on a delidded desktop CPU for better temps. So in the typical sense I am aware of the general knowledge of working with LM -- it's conductive, don't use too much, coat copper heatsinks with it before using so as to let it soak in to the copper, etc.
I'm confident I can do the job, What I am curious to know is if there is any particular information about repasting these Strix laptops that I should know about, like whether its best to use more LM on the GPU due to contact pressure differences, or any other particular pitfalls to be aware of?

dry microfibre cloth or qtips to remove most of it, then use alcohol to thoroughly clean residue

Hello,
If you are going to the trouble after 3 years then do everything in one go, Thermal Putty included on the CPU VRM / GPU VRM and GPU memory chips.
And some further info including thermal putty / cleaning

Liquid metal does react with copper so it's mainly used on nickel plated copper bases, if you used it on copper it cause pitting and the Gallium content within the liquid metal would end up coating the copper surface.
Which model do you have (G814?), check here to see if the GPU is using liquid metal.
