Thermal paste can last for many years. It will be necessary if the heat sink is removed. In most cases, it will last for the life of the machine but it depends on what you do with the machine. To be specific thermal paste can last up to 15 years in normal conditions. Machines that are heavy-duty may need a new coat more often.
