Intel Desktop Board DH57JG Technical Product Specification 2.5.2 Fan Header Current Capability CAUTION The processor fan must be connected to the processor fan header, not to the system fan header. Connecting the processor fan to the system fan header may result in onboard component damage that will halt fan operation. Table 29 lists the current capability of the fan headers. Table 29. Fan Header Current Capability Fan Header Maximum Available Current Processor fan System fan 2.0 A 1.5 A 2.5.3 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. 54

Fan Header Current Capability
CAUTION
The processor fan must be connected to the processor fan header, not to the system
fan header.
Connecting the processor fan to the system fan header may result in
onboard component damage that will halt fan operation.
Table 29 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.
