Greetings! A few weeks ago i posted a thread about my Macbook 3,1. Yes i know its not power PC but this post is still useful to the power PC community. last year i did the thermal paste on my macbook with Startechs metal oxide thermal CPU paste compound and it dropped temps. But now im thinking i need to do it again but better. Is silver arctic really better then this stuff? local computer shop says no, but whats your opinion?
