It's unlikely to be 'exhausted'.

The main problem is likely to be dust, etc. in the heatsink or the
fan. Taking the heatsink off the chip (perhaps in order to clean it)
can leave air bubbles in the thermal compound - air in this situation
acts as a brilliant heat insulator, which is less than ideal...

Removing and re-applying the thermal compound ensures that the
conductivity between chip and heatsink is a good way to help exclude
the air bubbles and any other contaminants that could interfere in the
cooling.
