I've replaced my MBP, the new one doesn't make the pop sound (for now, on the 1st day).
I don't remember that the previous machine does make sound in its first week, I only noticed the pop sound in the 2nd-3rd week of using.
Same here, had a number of replacements and the first few days would be fine, then it would start again.
