CHASS_FAN)
These connectors support cooling fans of 350mA (4.2 Watts) or less. Orient
the fans to blow air across the onboard heat sink. Depending on the fan
manufacturer, the wiring and plug may be different. The red wire should be
positive, while the black should be ground. NOTE: Rotations Per Minute (RPM)
can be monitored using ASUS PC Probe. (see 6. Software Reference).
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.
