What I should have added is that if a component is operating under its
rated operating temperature, it should live long and prosper. However,
when you get to the operating temperature boundary and hotter (or even
a little before you reach that boundary ), every extra calorie of heat
cuts in the the expected life of the component in a big way. In this
circumstance a cooler whould make a big difference. If the component
is oeprating under its rated temperature, cooling it will have little
effect. It's usually 'bargain' designs and designs which try to get
every ounce of compute power out of a chip, that are most like likely
to be running hot.
