Intel Desktop Board DP35DP Technical Product Specification

2.5.3

Add-in Board Considerations

The board is designed to provide 2 A (average) of +5 V current for each add-in board.

The total +5 V current draw for add-in boards for a fully loaded board (all six

expansion slots and the PCI Express x16 connector filled) must not exceed 14 A.

2.6

Thermal Considerations

CAUTION

A chassis with a maximum internal ambient temperature of 38 oC 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.

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 16) can reach a temperature of up to 85 oC in

an open chassis.
