Installing the Processor Fan Heat Sink
Intel Desktop Board DX58SO 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 or boxed thermal solution manual.
Connecting the Processor Fan Heat Sink Cable
Connect the processor fan heat sink cable to the 4-pin processor fan header (see
Figure 15). A fan with a 4-pin connector as shown in Figure 15, A is recommended;
however, a fan with a 3-pin connector (Figure 15, 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.
