Hardware Installation
• Be sure to connect fan cables to the fan headers to prevent your CPU and system from
overheating. 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.

 Themotherboardhasa4-pinCPUfanheader(CPU_FAN),ve4-pin(SYS_FAN1/2/3/4/5)andthe3-pin
(SYS_FAN6/7)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 motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed
control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the
chassis.

The power connector provide auxiliary power to the onboard PCI Express x16 slots. When two or more
graphics cards are installed, we recommend that you connect the SATA power cable from the power supply
totheATX4Pconnectortoensuresystemstability.
