3/4) CPU_FAN / SYS_FAN (Cooler Fan Power Connector)
The cooler fan power connector supplies a +12V power voltage via a 4-pin power connector and
possesses a foolproof connection design.
Most coolers are designed with color-coded power connector wires. A red power connector
wire indicates a positive connection and requires a +12V power voltage. The black connector
wire is the ground wire (GND).
Remember to connect the CPU/system fan cable to the CPU_FAN/SYS_FAN connector to prevent
CPU damage or system hanging caused by overheating.
5) IDE (IDE Connector)
An IDE device connects to the computer via an IDE connector. One IDE connector can connect to
one IDE cable, and the single IDE cable can then connect to two IDE devices (hard drive or optical
drive). If you wish to connect two IDE devices, please set the jumper on one IDE device as Master
and the other as Slave (for information on settings, please refer to the instructions located on the IDE
device). Before attaching the IDE cable, please take note of the foolproof groove in the IDE connector.
