Comment on Does a clean PC run better than one with a lot of dust in it?

Computers need to be relatively cool to function properly.
Dust acts as a heat insulator, trapping heat inside.
Dust also clogs the cooling fans from doing their job.
Most computers have built-in features that auto throttle or even self shut-down if the heat gets too high.
More dust = more heat = more speed throttling & shutdowns.
