3. Cleaning Practices
Best practices for removing dust from fans and
heat sinks
Even in a clinical environment, dust and other contaminants accumulate around fans and heat
sinks inside the Varex imaging system computer. Special attention must be paid to these areas
so that the airflow that cools the electronics can pass freely through the computer case and
heat sinks. Surfaces inside the computer are typically very dry and can be blown clean with
compressed air available at most retail stores that sell electronics.
Observing ESD precautions, use the compressed air to carefully remove all dust, hair, and
other impediments from the openings in the front and rear of the computer case, and from in
and around the CPU heat sink and fan.
Do not use a cloth, with or without cleaning solution, to clean internal components of the
computer. Cloth may be used, dampened with cleaning solution as desired, only to clean
external surfaces of the computer.
