2.5.2 Fan Header Current Capability
CAUTION
The processor fan must be connected to the processor fan header, not to a chassis fan
header. Connecting the processor fan to a chassis fan header may result in onboard
component damage that will halt fan operation.
Table 26 lists the current capability of the fan headers.

2.5.3 Add-in Board Considerations
The board is designed to provide 2 A (average) of +5 V current for each add-in board.
The total +5 V current draw for add-in boards for a fully loaded board (all six
expansion slots and the PCI Express x16 connector filled) must not exceed 14 A.
