Hardware Installation
• Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheat-
ing. Overheating may result in damage to the CPU or the system may hang.
• Thesefanheadersarenotcongurationjumperblocks.Donotplaceajumpercapontheheaders.
5/6) CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3/SYS_FAN4 (Fan Headers)
 Themotherboardhasa4-pinCPUfanheader(CPU_FAN),three4-pin(SYS_FAN1~SYS_FAN3)anda
3-pin(SYS_FAN4)systemfanheaders.Mostfanheaderspossessafoolproofinsertiondesign.Whencon-
nectingafancable,besuretoconnectitinthecorrectorientation(theblackconnectorwireistheground
wire).Thespeedcontrolfunctionrequirestheuseofafanwithfanspeedcontroldesign.Foroptimumheat
dissipation, it is recommended that a system fan be installed inside the chassis.

The fan header is 4-pin and possesses a foolproof insertion design. When connecting a fan cable, be sure
toconnectitinthecorrectorientation(theblackconnectorwireisthegroundwire).Thespeedcontrol
function requires the use of a fan with fan speed control design.
