If your MSI GS66 Stealth laptop (model 11UE-007) is having problems with the overall cooling system and it is not the cooling fan, the thermal paste might need to be replaced.
Thermal paste is used to transfer heat away from the CPU and the cooling system. Loss of effectiveness from this part can result in the laptop heating up to dangerous levels that put other components of the laptop at risk.
This part can dry up over time and will need replacement at some point. This guide has the necessary steps to fully replace the thermal paste and return the laptop to peak efficiency.

When putting the heatsink back on, do we only need to reapply cpu thermal paste, or do we have to replace the pink stuff? If so, what is the pink stuff, and where can I get it?
If you only have issues with thermals on your cpu then I would just replace the gray thermal paste directly on the cpu. The “pink stuff” is also thermal paste for the other components. It would normally have thermal pads but there must not have been enough room for them in the design.
