Chapter 2: Hardware information

10) CPU Fan, Power Fan, and Chassis Fan Connectors

(3x3 pin CPU_, PWR_, CHA_FAN)

Three fan connectors support cooling fans of 350mA (4.2 Watts) or less.
Orient the fans so that airflow flows across the onboard heat sinks instead of
expansion slots. The fan wiring and plug vary depending on the type
employed. Connect the fan cable to the connector, ensuring that the black
wire matches the ground pin. (Use the “Rotation” signal only with a specially
designed fan with a rotation signal. You can monitor the Rotations Per Minute
(RPM) using ASUS PC Probe (see 6. SOFTWARE REFERENCE).
