6) NB_FAN (North Bridge Fan Header)
Connect the North Bridge fan cable to this header. The fan header has a foolproof insertion design.
When connecting a fan cable, be sure to connect it in the correct orientation. Most fans are designed
with color-coded power connector wires. A red power connector wire indicates a positive connection
and requires a +12V voltage. The black connector wire is the ground wire.
