Beyond warmer temperatures and additional noise from the fan working overtime to cool its operating environment, you can expect to see slower performance. Long term, damage to core components may occur—for example, heat can affect battery life on a laptop.

Tested: Will the new i7 Mac mini run faster with new thermal paste?

Your Mac is not alive, but where heat and airflow is concerned, it's essentially a breathing thing—give your Mac some room to breathe.

Check Your Mac’s Temperature

As beautifully constructed as your Mac tends to be, a point will come when the thermal paste—the paste that's used to fill the microscopic air gaps found in electronic equipment and that helps dissipate heat inside your Mac—will dry out and become less effective in its task.
