![]() In a shop-floor environment, we have seen standard PCs become so clogged with dirt literally in one day that they stopped running because of overheating. Industrial environments are often filthy, so much so that standard PCs are unusable. The severity of the problem depends on the environment. If there's any dust in the air at all, the system fans will suck it in and deposit it inside the case, where it will become a problem sooner or later.

Fans suck dust, pet hair, and other contaminants into the case, where they rest on every surface. Dirt is nasty stuff.Ĭomputers become dirty as a natural part of running. Dirt worms its way into connectors, increasing electrical resistance and reducing reliability. Dirt causes fans to run faster (and louder) as they attempt to keep the system cool. ![]() Dirt acts as thermal insulation, causing components to overheat and thereby shortening their service lives. ![]() Dirt blocks air flow, causing the system to run hotter and less reliably.
