Using the guide for your machine I would open it, clean it of dust and replace the thermal paste. You must completely remove the thermal paste and replace it following the guide. BE CAREFUL disconnecting components to get at the heat sink! You can tear off or damage the connectors for HD ribbon cables and Fan/temperature indicators very easily.
