Fan Headers
This motherboard has eight fan headers
(Fan1 to Fan8). These 4-pin fans headers
are backward compatible with 3-pin fans.
However, fan speed control is available
for 4-pin fans only. The fan speeds are
controlled by the BIOS. See the table on the
right for pin definitions
Serial Ports
The COM1 serial port is located beside the
VGA port. Refer to the motherboard layout
for the location of the COM2 header. See the
