Instructions
Examine the immediate surroundings of the PlayStation 3 unit. Observe whether there are any objects blocking the fan. Also, placing the unit on the carpet or near curtains can sometimes interfere with the proper ventilation of the system. Reposition your PlayStation 3 so that the fan is in more open air.
Look at the vents on the rear of the PlayStation 3 unit. If there is significant dust build-up, use a can of compressed air to remove the dust which may be interfering with ventilation.
Shorten your gaming or movie session times so that you are not running the system for extensive periods of time. It is good to allow the system to cool after several hours of use.
Contact Sony for information on sending your system for repair. If the overheating is caused by issues with the cooling fan, sending your PlayStation 3 to the manufacturer is the solution of last result. Any attempted self-repair will void the warranty.
