I bought this thermal grease to fix my YLOD (yellow light of death) on my 1st Gen PlayStation 3.  A buddy mine recommended that I try this Arctic Silver thermal grease.  This grease is awesome!  I was expecting it to be more like a thick liquid, but it was really thick and easy to apply.  I have seen videos online of how to fix PS3's, and most of them use a much thinner grease that is harder and messier to apply.  I just put a dime-sized ball in the center of the chips, and pressed the heat sinks back on.  Just to make sure that I was doing it right, I removed the heat sink.  The Arctic Silver had flowed perfectly and evenly from the center and was razor thin with absolutely no air bubbles.
