Assuming you can keep a device in its "normal operating (temperature)

temperature)?

If all you're thinking of is MTBF, adding the complexity of an active
cooling element is a big step in the wrong direction for the system.

Reducing the thermal impedance of the source, to ambient is the
usual way to go, when addressing a specific aging factor.

If you're thinking of performance, It's cheaper and more reliable
to concentrate on reducing the temperature of the point source, not
the rest of the planet.
