Cleaning the Interior of the Server

One important item in a good maintenance program is regular and thorough cleaning of
the interior of the server, especially around the motherboard.
Dust buildup inside the server can lead to several problems. As dust acts as a thermal
insulator, a buildup can prevent proper system cooling. Excessive heat will shorten the
life of server components. Also, dust may contain conductive or corrosive materials
that can cause short circuits or corrosion of electrical contacts.
How often you should clean the interior of the server depends on the environment in
which it is located. For most office environments, you probably should clean the server
every 12 months. For more severe environments, clean the interior every 6 months.
