23.Chassis, CPU , & PowerSupply Fan Connectors (3-pin CHA_, CPU_, PWR_FAN) These connectors support cooling fans of 500mAMP (6 Watts) or less. Orien- tate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan’s plug to the board taking into consid- eration the polarity of the this connector. NOTE: The “Rotation” signal is to be used only by a specially designed fan with rotation signal.

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.

24.ATX Power Supply Connector (20-pin block ATXPWR)25.ATX Power Supply Fan Control Connector (6-pin block)

This connector connects to a ATX power supply. The plug from the power supply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned. If you have an ATX 2.01 power supply, a 6 pin cable can be connected to the motherboard in order to control the power supply’s fan and monitor rotation.

IMPORTANT: Make sure that your ATX power supply can supply at least 10mAmp on the 5-volt standby lead (5VSB). You may experience difficulty in powering on your system if your power supply cannot support the load. For Wake on LAN support, your ATX power supply must supply at least 720mAmp.
