3/4) CPU_FAN/SYS_FAN1/2/3 (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.
