3/4) CPU_FAN/SYS_FAN (Fan Headers)
All fan headers on this motherboard are 4-pin. 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.
• 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.

 Withtheuseofthepowerconnector,thepowersupplycansupplyenoughstablepowertoallthecomponents
onthemotherboard.Beforeconnectingthepowerconnector,rstmakesurethepowersupplyisturned
off and all devices are properly installed. The power connector possesses a foolproof design. Connect the
power supply cable to the power connector in the correct orientation.
 The12VpowerconnectormainlysuppliespowertotheCPU.Ifthe12Vpowerconnectorisnotconnected,
the computer will not start.
To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption
beused(500Worgreater).Ifapowersupplyisusedthatdoesnotprovidetherequiredpower,theresultcan
lead to an unstable or unbootable system.
