This chapter provides you with information about hardware installation
procedures. It is recommended to use a grounded wrist strap before
handling computer components. Electrostatic discharge (ESD) can
damage some components.

The VIA EPIA-N700 mainboard is packaged with a standard VIA C7 1.5
GHz NanoBGA2 processor. The processor requires a heatsink with fan to
provide sufficient cooling.
CPU Fan and System Fan: CPU_FAN and SYS_FAN
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.
