3/4)CPU_FAN/SYS_FAN1/SYS_FAN2/SYS_FAN3(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 APU and system from
overheating. Overheating may result in damage to the APU or the system may hang.
• Thesefanheadersarenotcongurationjumperblocks.Donotplaceajumpercapontheheaders.
