Connect the CPU fan to this
connector.
Use this connector if you are installing
an additional fan in the unit.
The chassis fan will provide adequate
airflow throughout the chassis to
prevent overheating the CPU.
When using two IDE drives on the same
connector, one must be set to Master mode
and the other to Slave mode. Refer to your
disk drive user's manual for details.
The PW1 and PW12 Power Connector must
be used simultaneously.
