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.
