I have a PS3 20GB from Japan. This works well, in addition to the ability to play DVDs, because some bs in the region code. My question is, I am new to the PS3 world. My friend is pretty new and if it rises, which are very strong. You can hear the fans, the other from the room. When I mention is in the mine to 100%. I'm impressed. It seems to work a little too hot, but there was nothing done about the performance of the system yet. I was wondering if someone knows if the fans as an upgrade of new models, or what? I only hope I have any fans here has failed. If my XBOX 360 has caught fire by a Sony product, so I'd be upset.
