This part of the disassembly is the part that you really don’t want to tamper with unless you know what you are doing! This part will definitely void your warranty because a lot can go wrong with this part underneath the copper cooling pipes is your CPU and your dedicated GPU, these are basically the brains of your laptop.

They control the computational stuff that makes the laptop work as it should and are in charge of your graphics so these need to be cooled down

The least you can do here is redo the thermal paste and blow out the fans that’s it!! Note these only apply if you know what you are doing.
