How can I safely repaste the cpu thermal paste?

I see a couple videos here: gen 7 disassembly and similar computer (x1 carbon) repaste tutorial

And I see a gen 5 tutorial here.

However, the gen 7 disassembly video doesn't go over how to repaste the thermal paste, and the x1 video isn't the gen 7 x1 yoga. And the Ifixit tutorial is for the 5th gen.

My question is, can I follow the gen 5 tutorial, or will the innards be very different? What about the x1 carbon repaste tutorial, is that fine?

Are there unique differences to this model I should be aware off?

I appreciate any help,

Thanks
