Each memory fan (Group A) uses 8-pin connector, which is connected to fan connector on
mother board (Connector BB and Q in Figure 5).
Each processor fan (Group B) uses 4-pin connector, which is connected to processor fan
connector on mother board (Connector S, T and Y, Z in Figure 5).
The fan connector pin-out definition is as follows:

4.3 Power Supply Fan
Each power supply module supports one non-redundant 40 mm fan. The fans control the
cooling of the power supply and some drive bays. These fans are not replaceable.
Therefore, if a power supply fan fails, you must replace the power supply module.

Air Duct Module
The chassis requires the use of an air duct module to direct airflow over critical areas within
the system. The following provides a summary and description of Air Duct Module.
