You must have been working with at least quite young people or something. My experience goes the other way. I've seen people who bought a new computer because their fans were running at max and the reason for that was that they were full with dust and dog hair.

I "fixed" someone's computer that would regularly crash a few minutes after starting it by vacuuming the dust out. :)
