Fan Interface Connector
The system board has five 3-pin, shrouded, and keyed fan connectors. Two are located
next to the processor sockets (one for each processor) for a tachometer fan heat sink.
Note:
Heatsink fans are not used with some processors.
Note:
Fan connectors 2A and 2B can not be used
simultaneously. If you plug fans into both connectors, the fans will
not operate properly.
