Chosen Solution

I want to change thermal paste on this device.

Surprising this system does not use any TIM !! See for your self review the IFIXIT teardown here: Retina MacBook 2016 Teardown. And this IFIXIT guide: Retina MacBook 2016 Logic Board Replacement This ultra low power CPU based system has its limits. It’s not designed to be more than a web surfer or school notebook. I think you’ll need to get a more powerful system if your system is thermally throttling.
