CPU/CASE Cooling Fan Connectors
(
FAN1/FAN2)
These added connectors allow the fan to draw
their power from the mainboard instead of the disk
drive connector.
The board's management extension hardware is
able to detect the CPU and system fan speed in
rpm (revolutions per minute). These connectors
supports 3-pin cooling fans with minimum of
3500 RPM. The wiring and plug may vary
depending on the manufacturer. On standard fans,
the red is positive (+12V), the black is ground,
and the yellow wire is the rotation signal.
LTI-II Riser (LTI1) Optional
This connector is to be connected to an optional
TV/LCD/2nd CRT Output adapter card.
