Fan Interface

The server board has five 3-pin fan connectors that are shrouded and keyed. Two are located next to the processor sockets (one for each processor); each is intended to be used for a tachometer fan heat sink.

/NOTE

Fan connectors 2A and 2B can not be used simultaneously. If you plug fans into both connectors, the fans will not operate properly.
