This is a widely debatable topic, but is different topic than what
this thread was started on.  But I might add that CPU fans are killed
mostly by dirt. If they stayed perfectly clean they'd last a lot
longer. Dirt gets into the fan and on the fan blades, gets it out of
balance, causes resistance, makes it spin slower, ruins the bearings.

It's been my experience that computers have fewer problems when run
continuous, but they need a good [gentle] cleaning  at least once a
year - get all the dust out, clean the CPU fan [gently], and CPU heat
sink, maybe even new thermal grease, etc. AND, all CPU fans are not
created equal and some may last longer than others. (I use a small
paint brush for cleaning.) ....wow, we're getting way, way off topic
on this thread... sorry....  :)
