Hardware Setup
Fan Power Connector: CPUFA1
The CPUFA1 (processor fan) supports system cooling fan with +12V. It sup-
ports three-pin head connector. When connecting the wire to the connectors, al-
ways take note that the red wire is the positive and should be con-
nected to the +12V, the black wire is Ground and should be con-
nected to GND. If the mainboard has a System Hardware Monitor
chipset onboard, you must use a specially designed fan with speed
sensor to take advantage of the CPU fan control.
Front Panel Audio Connector: JAUD1
The JAUD1 front panel audio connector allows you to connect to the front
panel audio and is compliant with Intel
®
Front Panel I/O Connectivity Design Guide.
MSI Reminds You...
Always consult the vendors for proper CPU cooling fans.

If you don’t want to connect to the front audio header, pins
5 & 6, 9 & 10 have to be jumpered in order to have signal
output directed to the rear audio ports. Otherwise, the
Line-Out connector on the back panel will not function.
