is virtually constant and independent of the speed and
direction of airflow across the heat sink.
9.3.2 Optional auxiliary fan attachment
The boxed processor’s passive heat sink includes features that allow for attachment of a standard auxiliary
fan to improve airflow over the passive heat sink. A standard 40mm, 50mm, or 60mm fan can be attached.
System integrators must evaluate the thermal performance of their system (see above) and consider the
baseboard manufacturer’s recommendations for thermal management before deciding if an auxiliary fan is
warranted. If an auxiliary fan is needed (e.g. for the front processor in a multiprocessor system), it may be
attached to the face of the boxed processor’s passive heat sink. To facilitate this, the boxed processor’s
passive heat sink will include features in the heat sink fins onto which fan mounting hardware can be attached.
The appropriate fan attach hardware will be included with the boxed Pentium® III Xeon™ processor at 600
MHz+ if necessary. The boxed Pentium III Xeon processor at 600 MHz+ does not ship with an auxiliary
fan.

9.3.2.1 Clearance recommendations for auxiliary fan
If an auxiliary fan is used, clearance must be provided in front of the boxed processor passive heat sink to
accommodate the mechanical and airflow clearance requirements of the fan and mounting hardware.
Baseboard-mounted components and chassis members should not violate the clearance requirements for the
auxiliary fan. Figure 38 and Figure 39 show the clearance recommended for the fan and air inlet. Required
airspace clearance for fans may vary by manufacturer. Consult your fan manufacturer and/or fan
documentation for specifications.
