• Do not forget to connect the fan cables to the fan connectors. Insufcient air ow inside
the system may damage the motherboard components. These are not jumpers! Do not
place jumper caps on the fan connectors!
• For system stability, ensure that you connect a chassis fan to the motherboard.
2. CPU and chassis fan connectors (4-pin CPU_FAN, 3-pin CHA_FAN)

audio I/O module cable to this connector.
• We recommend that you connect a high-denition front panel audio module to this
connector to avail of the motherboard’s high-denition audio capability.
• If you want to connect a high-denition front panel audio module to this connector, set
the Front Panel Type item in the BIOS setup to [HD]. If you want to connect an AC'97
front panel audio module to this connector, set the item to [AC97]. By default, this
connector is set to [HD]. See section 2.5.5 Onboard Devices Conguration for details.
