Installing the Processor Fan Heat Sink
Desktop Board D975XBX has an integrated processor fan heat sink retention mechanism (RM).
For instructions on how to attach the processor fan heat sink to the integrated processor fan heat
sink RM, refer to the boxed processor manual or the Intel World Wide Web site at:
Integration of the Boxed Intel® Pentium® 4 Processor in the 775-Land Package
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. Since the 3-pin fan cannot use the on-board fan control, the
fan will always operate at full speed.
