Greetings, good folks!

Got Asus Rog Strix G16, 13450hx 4060.
So far performance seems fine, CS2 works great but in something like Control with RT max temperatures are going into red zone (HWInfo64 showed up to 95 on GPU memory and 97 on CPU package).

Never really had gaming laptop, so I have couple questions.
Should I even bother with those? Temperatures are not consistent, just maximum numbers aren't nice. Strix cooling should be fine for these hardware but from another side, what if liquid metal melt a bit and screw everything up?

Will undervolt void the warranty?

What are the numbers to start with this CPU? I really couln't find anything useful for this exact model. Should I just use the same undervolt numbers as people recommend for 13650hx? What will happen if I will put voltage too low?

Does laptop stand actually make a difference? So far as I can see it only works for cheaper models with bad cooling, making no difference for something like Strix or higher models.
