Users are complaining that a number of PS3s are making an annoying, high pitched noise while playing games. They’ve narrowed down the problematic PS3s to those with serial numbers CE133212XXX or CE133190XXX. (Remember how the PSone always overheated during extended gaming sessions, or the “dirty disc error” that the PS2 throws at you all the time? I see a pattern of shoddy manufacturing.)
So if you don’t want to deal with this all day, make sure your shiny new PS3 doesn’t have either serial.
Playstation 3 making a high pitched whine noise? [PlayStation.com Forums via Ars Technica]
playstations always make a dodgy noise when playing sounds like a rumatic drill
no
Try going into ’sound settings’ then ‘HDMI settings’ and make sure you have it set to ‘automatic’
This happened for me and this step took care of it..
Good luck
