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 co
nnector 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 wi
th a 3-pin connector cannot use the onboard fan control, the fan will always
operate at full speed.
