Installing and Replacing Desktop Board Components

Installing the Processor Fan Heat Sink

Intel Desktop Board DP45SG has mounting holes for a processor fan heat sink. For instructions on how to attach the processor fan heat sink to the Desktop Board, refer to the boxed processor manual.

Connecting the Processor Fan Heat Sink Cable

Connect the processor fan heat sink cable to the 4-pin processor fan header (see Figure 12). A fan with a 4-pin connector as shown in Figure 12, A is recommended; however, a fan with a 3-pin connector (Figure 12, B) can be used. However, since the fan with a 3-pin connector cannot use the onboard fan control, the fan will always operate at full speed.
