System fan and air duct
8.1 Basic information
Figure 67: Fan module
The fan module consists of the system fan contained in an air duct directing
airflow directly onto the CPU heat sink and memory slots.
I Additional fans in power supply units are integral parts of the power
supply units and cannot be replaced separately.
V CAUTION!
Since the system fan is not redundant is has to be replaced immediately
in case of defects or prefailure events.
