Hey, no problem.  These forums are a place to discuss different ideas, and opinions.  IMHO, the P4 HS/Fan retention mechanism is one of the best I have ever seen.  Heck of a lot better than the old clip on style that the Socket 370 used.  I've put together quite a few P4 rigs now.  All of them using the stock HS/Fan, all of them overclocked.  Not a single issue with any of them.  No thermal issues, no mechanical issues either.
