Installing the Processor Fan Heat Sink
The desktop board 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:
http://support.intel.com/support/processors/pentium4/intnotes478.htm
Connecting the Processor Fan Heat Sink Cable
Connect the processor fan heat sink cable to the 4-pin processor fan connector (see Figure 11).
NOTE
If a 3-pin fan connector is used in a 4-pin fan header, the fan will not be controlled and will run at
full speed.
