What do I replace the original thermal materials with?
I am reinstalling my recently repaired logic board in my G3 900mhz iBook 14". The original thermal heat transfer materials on the heat sink were two preformed squares, the larger was a blue foam looking square, the other smaller one was gray and seemed to be a more solid version and consistency of thermal paste. Can I use the normal Arctic Silver paste for the installation or do I need to find the same type of original squares?
