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 a 
fan with a 3-pin connector cannot use the onboard fan control, the fan will always 
operate at full speed.
