That sounds about normal to me.

so yeah.. looks normal

Quad is a huge silicon die, also 45 watts TDP, and you need to redo the thermal paste with better one. Artic silver 5 or Thermal Grizzly Kryonaut 1g with around 12w/mk tube or Hydronaut by 2 w/mk less but cheaper.
This is required to get best use of heat conduction because this is high end machine.

This is what this CPU looks like.

He already used Kryonaut to replace the old TIM. Still the bottleneck is the relatively small heatsink rather than thermal transfers between CPU and heatsink.

I have a similar machine, EB 8740w and temps are normal. It's a very solid machine. I have stressed mine a lot (I have a i7-3740Q in it) with multi-threaded compilations for hours that made the temp rise up to 98C for extended periods of time and it never had a problem. But in normal operation including games, it usually doesn't go over 60-70C.

thank you thank you !
😁 its all i wanted to read ! its an amazing laptop !

I refine the heatsink by lightly lapping with 600 grit sandpaper wrapped around with excess as handle small piece of metal cut from old cpu IHS. Lap once to check how much warp of the heatsink.

I do this on all the PS4 (all models) and Xbox one (all models) and both Xbox series S/X consoles I repair at work too. PS5 left alone. They were rough and some has bad wave. So far I heard nothing from people with repaired consoles and this was going on for 4 years.

But I need your attention: Xbox one (all models) and both Xbox series S/X consoles has major issue with type of thermal interface material. Even at 1 year old, the TIM has air bubbles over whole area of silicon die with
re-hardened excess TIM (yes, lot) as spacer around the die holding APU and heatsink apart, hence the air bubbles.
You need to fix that by remove old TIM and use MX-4 or MX-5, AS5, Hydroanaut or noctua NT-H2 and described above light lap. Also inspect carefully for flattened shiny particles and gently rub away with edge of PCB board. This leaves no mark on the silicon die and heatsink. X-clamp not the issue, I bend them bit more for more force.
