Fan Header Current Capability; Add-In Board Considerations - Intel BOXDQ67EPB3 Specification

2.6.2

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 28 lists the current capability of the fan headers.

Add-in Board Considerations

The board is designed to provide 2 A (average) of current for each add-in board from
the +5 V rail. The total +5 V current draw for add-in boards for a fully loaded board
(all expansion slots filled) must not exceed the system's power supply +5 V maximum
current.
Maximum Available Current
