CPU

The VIA NAB-7500 mainboard is packaged with a standard VIA C7

1.5GHz NanoBGA2 processor. Other processor speeds (i.e., 2.0GHz and

1.0GHz) are also available as manufacturing options. The VIA C7

1.5GHz processor requires a heatsink with fan to provide sufficient

cooling.

CPU Fan and System Fan: CPUFAN and SYSFAN

The CPU_FAN (CPU fan) and SYS_FAN (system fan) run on +12V and

maintain system cooling. When connecting the wire to the connectors,

always be aware that the red wire (positive wire) should be connected to

the +12V. The black wire is Ground and should always be connected to

GND.
