Pushsquare made a poll with over 6000 votes and almost 70% have answered if they had coil whine with "Yes".
2nd poll with 4800 votes, 45% say that they only hear it with sound muted.
Last poll with 4800 votes has 53% saying the hey only hear it while playing games.
Whirred and wonderful

6000 votes is a representative sample... but SDF is going to claim that xbots have rigged the poll, so it's all a lie. /shrug
I hope you get lucky with your new replacement Hostile. I personally have accepted coil whine as an integral part of the Playstation experience.
