I have only repasted when having to remove the heatsink/fan from the CPU, haven't had any issue and I use Arctic Silver, have been since started building in a shop in '94. I don't smear it, use a 'glop' about the size of the nail on a pinky finger and let the pressure of clamping down the heatsink spread it out, avoids gaps/air pockets in the paste.
