I have a overheating Sony Vaio laptop and was planning on taking it apart and replacing the thermal paste. Doing research I found out that the heatsink on my laptop has three metal bases. Two with copper and one with another material, it also has black squares (thermal pads?). I am wondering what materials (excluding thermal paste) I will need to buy to fix my over heating issues. At the moment it heats up to about 70 degrees with normal use (Google Chrome).
