I don't know ! To be honest haven't used a stock cooler in years on a build....I have gone with 3rd party as far back as I remember, and while I get rigs in that have stock on them for repairs and upgrades......they aren't new, so I would think some sound would be expected from age....Thinking about it, it wouldn't surprise me if they did, can always check that the legs are snug, and check the fan when off to see if anything is in between the blades, blow it out with compressed air if available.....
