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.
4/5) CPU_FAN/SYS_FAN1/2/3/4/5/6/7 (Fan Headers)
 Themotherboardhasa4-pinCPUfanheader(CPU_FAN),ve4-pin(SYS_FAN1/SYS_FAN2/SYS_FAN3/
SYS_FAN4/SYS_FAN5)andtwo3-pin(SYS_FAN6/SYS_FAN7)systemfanheaders.Mostfanheaders
possess 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. For optimum heat dissipation, it is recommended that a system fan be
installed inside the chassis.
