Intel Desktop Board DQ77KB Technical Product Specification
76
2.7.2 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 45 lists the current capability of the fan headers.
Table 45. Fan Header Current Capability
Fan Header Maximum Available Current
Processor fan 2.0 A
System fan 1.5 A
2.7.3 PCI Express Add-in Card Considerations
The motherboard is designed to provide up to 25 W to the PCI Express x4 slot. The
total power consumption from add-in boards on this slot must not exceed this rating.
2.8 Thermal Considerations
CAUTION
A chassis with a maximum internal ambient temperature of 38
o
C at the processor fan
inlet is a requirement. Use a processor heat sink that provides omni-directional airflow
to maintain required airflow across the processor voltage regulator area.
CAUTION
Failure to ensure appropriate airflow may result in reduced performance of both the
processor and/or voltage regulator or, in some instances, damage to the board. For a
list of chassis that have been tested with Intel desktop boards please refer to the
following website:

All responsibility for determining the adequacy of any thermal or system design
remains solely with the reader. Intel makes no warranties or representations that
merely following the instructions presented in this document will result in a system
with adequate thermal performance.
