Add-In Board Considerations; Thermal Considerations - Intel D945GCLF2 Technical Product Specification

2.5.3

Add-in Board Considerations

The board is designed to provide 2 A (average) of +5 V current for the one add-in
board. The total +5 V current draw for the one add-in board must not exceed 2 A.
2.6

Thermal Considerations

CAUTION
A chassis with a maximum internal ambient temperature of 38
inlet is a requirement.
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:
http://developer.intel.com/design/motherbd/cooling.htm
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.
CAUTION
Ensure that the ambient temperature does not exceed the board's maximum operating
temperature. Failure to do so could cause components to exceed their maximum case
temperature and malfunction. For information about the maximum operating
temperature, see the environmental specifications in Section 2.8.
CAUTION
Ensure that proper airflow is maintained in the processor voltage regulator circuit.
Failure to do so may result in damage to the voltage regulator circuit. The processor
voltage regulator area (shown in Figure 14) can reach a temperature of up to 85
an open chassis.
