AIMB-253 Mainboard
Fan Power Connectors: CPUFAN1, SYSFAN1
The fan power connectors support system cooling fan with +12V. When connecting the
wire to the connectors, always take 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. If
the mainboard has a System Hardware Monitor chipset on-board, you must use a spe-
cially designed fan with speed sensor to take advantage of the CPU fan control.
Important
Please refer to the recommended CPU fans at Intel
consult the vendors for proper CPU cooling fan.
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
tivity Design Guide.
