Airflow Support

Fan
System Fan #1 and #2
System Fan #3
System Fan #4
To control airflow within the system, the system uses a CPU air duct to isolate and direct airflow
to three critical zones: power supply zone, PCI zone, and CPU/memory zone.

Drive Bay Population

To maintain proper air pressure within the system, all hard drive bays must be populated with
either a hard drive or drive blank.
