JFP1 Pin Definition
Front Panel Connector: JFP1
The mainboard provides one front panel connector for electrical connection to the
front panel switches and LEDs. The JFP1 is compliant with Intel ® Front Panel I/O
Connectivity Design Guide.
Fan Power Connectors: CPUFAN1, SYSFAN1
The fan power connectors support system cooling fan with +12V. When connecting
the wire to the connectors, always note that the red wire is the positive and should
be connected to the +12V; the black wire is Ground and should be connected to GND.

specially designed fan with speed sensor to take advantage of the CPU fan control.
