How about you guys stop being a bunch of assholes and actually try to help the guy? What is it with this forum? Jesus.
Do you have it enclosed in a cabinet? The PS3, like the 360, likes to be out in the open. If you enclose it, it will get hot. Move it out of the cabinet and make sure its vents aren't blocked. When I had a PS3, it was silent once I took it out of my entertainment center enclosure.
