I have been working with electronics most of my life, most of all problems could have been prevented with added cooling or vent fans.
With one exception of cranking your stereo to max volume.

Sorry mean cranking any Electrical/Mechanical equipment to Maximum operating input/output for extended periods of time.
To answer your question Yes cooling helps to extend the life of many Electrical/Mechanical items.
