Intel Desktop Board D945PLRN Technical Product Specification 2.10 Electrical Considerations 2.10.1 DC Loading Table 31 lists the DC loading characteristics of the boards. This data is based on a DC analysis of all active components within the board that impact its power delivery subsystems. The analysis does not include PCI add-in cards. Minimum values assume a light load placed on the board that is similar to an environment with no applications running and no USB current draw.
Technical Reference 2.10.3 Fan 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 32 lists the current capability of the fan connectors. Table 32. Fan Connector Current Capability Fan Connector Maximum Available Current Processor fan 3.0 A Front chassis fan 1.5 A Rear chassis fan 1.
Intel Desktop Board D945PLRN Technical Product Specification 2.11 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 heatsink that provides omni-directional airflow (similar to the type shown in Figure 19) to maintain required airflow across the processor voltage regulator area. OM16996 Figure 19.
Technical Reference 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 (item A in Figure 20) can reach a temperature of up to 85 oC in an open chassis. Figure 20 shows the locations of the localized high temperature zones.
