Hello,

on attached picture - macbook pro 2017 a1708 (illustrative picture) you can spot CPU ready for the new thermal paste. But it has 3 surface areas, I spot on youtube people usually put paste on all three but I also read that one of them is PCH - platform controller hub and this one should be without thermal paste as it could cause transfer of heat from CPU to PCH and damage it.

QUESTION: Is one of them really PCH? And should I avoid putting paste on it? If yes, which one is it? Please comment based on attached picture wherewe can see A) left one B) Middle one C) Right one

Thank you very much!
