Intel Desktop Board D925XCV/D925XBC Technical Product Specification
2.11.3Fan Connector Current Capability
CAUTION
The processor fan must be connected to the processor fan connector, not to a chassis fan connector. Connecting the processor fan to a chassis fan connector may result in onboard component damage that will halt fan operation.
Table 38 lists the current capability of the fan connectors.
Table 38. Fan Connector Current Capability
Fan Connector | Maximum Available Current |
|
|
Processor fan | 1000 mA |
|
|
Front chassis fan | 800 mA |
|
|
Rear chassis fan | 800 mA |
|
|
Auxiliary rear fan | 800 mA |
|

✏NOTE
The auxiliary rear fan is available only on the D925XCV board. It is not available on the D925XBC board.
2.11.4Power Supply Considerations
CAUTION
The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options.
System integrators should refer to the power usage values listed in Table 37 when selecting a power supply for use with the board.
Additional power required will depend on configurations chosen by the integrator.
The power supply must comply with the following recommendations found in the indicated sections of the ATX form factor specification.
•The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2)
•The current capability of the +5 VSB line (Section 4.2.1.2)
•All timing parameters (Section 4.2.1.3)
•All voltage tolerances (Section 4.2.2)
