Just a question to all PS3 owners, do you ever clean out the inside of your PS3? I've had my PS3 about 2 or 3 years and it has recently become REALLY loud. It hums and buzzes so loudly when it's turned on, especially when there is a disc in it. It never used to be so loud. I thought it could be because of dust build-up on the inside. I've never opened it up or anything before, but I'm considering doing it to try clean it out and see if I can make it quieter. Has anyone ever successfully done this? Or is there some other reason why it would suddenly be really loud?
