Yes and no. It's true if they're never subjected to overvoltage,
overclocking or overheating (by being denied sufficient ventilation,
usually). But processors don't always operate in benign circumstances.

I just lost a two-year-old P4 CPU in my desktop system because I neglected
to clean out what turned out to be an huge amount of dust _between the
CPU heatsink fins_! I'll never make that mistake again.

I decided to upgrade my motherboard when I got the new CPU and the new MB
has variable CPU fan control. I discovered that when I put the side on
the cabinet, the CPU fan quickly speed up from the 2500 RPM at which it
ran with the case open to about 3800 RPM (in a fairly cool room, though
not a frigid machine room). From this I conclude that ventilation in the
main compartment of this case is rather poor. I plan to add a front-panel
fan to the cabinet.

When I told a friend about my system's recent breakdown, he mentioned that
he once had a laptop that would begin to malfunction if used with the top
closed (by using an external CRT monitor). Opening the lid allowed it to
cool just enough for the malfunctions to cease.

A lot of modern computer systems are designed or operated at the very edge
of their acceptable environmental parameters, and that's not a recipe for
reliability or longevity.

This is probably true, too, but nowadays, there are lots of good uses for
non-cutting-edge computers (unlike those based on a first-generation
Pentium, say, or a 100 MHz PowerPC chip--and even those systems can have
uses for some people), so while some may be willing to walk away from a
system after a few years, others may want to consider them a longer-term
