Fans

The exhaust fans provide airflow through the system to keep the interior 
temperature to acceptable levels. Do not block the vents for these fans. If a 
fan stops working, replace it immediately. Excessive heat within the chassis 
can damage other system components.

unauthorized access to the system and its peripherals.
