Motherboard Information
4.
CPU and Chassis Fan Connectors
The two 3-pin fan connectors (CPU_FAN, CHA_FAN) support
cooling fans of 350mA (4.2 Watts) or less. Orient the fans so that
the heat sink fins allow airflow to go across the onboard heat
sink(s) instead of the expansion slots.
The fan wiring and plug
may vary depending on the fan manufacturer. The red wire should
be positive while the black should be ground. Connect the fan
plug to the board taking into consideration the polarity of the
connector.
NOTE:
Use the “Rotation” signal only with a specially designed fan
with a rotation signal. The Rotations Per Minute (RPM) can be
monitored using ASUS PC Probe (see
4.3 Install the Operating
System
).
5.
IDE Activity LED (2-pin IDELED)
This connector supplies power to the cabinet’s IDE activity LED.
Read and write activity by devices connected to the Primary or
Secondary IDE connectors cause the IDE LED to light up.

WARNING!
The CPU and/or motherboard will overheat if there is no airflow across
the CPU and onboard heatsinks.
Damage may occur to the
motherboard and/or the CPU fan if these pins are incorrectly used.
These are not jumpers, do not place jumper caps over these
pins.
