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. 

Pin Signal 
1 FANIO
