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.
