12) CPU Fan, North Bridge Fan, and Chassis Fan Connectors
(CPU, NB, CHA_FAN)
The three fan connectors 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 sinks instead of the expansion slots. The fan wiring and plug may vary.
Connect the fan cable to the connector making sure that the black wire matches
the ground pin. NOTE: Use the “Rotation” signal only with a specially designed
fan with a rotation signal. Monitor Rotations Per Minute (RPM) using ASUS PC
Probe (see section 6. SOFTWARE REFERENCE).
