Intel Desktop Board DG33BU Technical Product Specification

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 15) can reach a temperature of up to 95 oC in an open chassis.

Figure 15 shows the locations of the localized high temperature zones.
