This section documents the mechanical specifications of the boxed Pentium 4 processor on 90 nm 
process in the 775-land package. The boxed processor will be shipped with an unattached fan 
heatsink. 

 shows a mechanical representation of the boxed Pentium 4 processor in the 

775-land package. 

Clearance is required around the fan heatsink to ensure unimpeded airflow for proper cooling. The 
physical space requirements and dimensions for the boxed processor with assembled fan heatsink 
are shown in 

 (side view), and 

 (top view). The airspace requirements for the 

boxed processor fan heatsink must also be incorporated into new baseboard and system designs. 
Airspace requirements are shown in 

 and 

. Note that some figures have 

centerlines shown (marked with alphabetic designations) to clarify relative dimensioning. 

1. Diagram does not show the attached hardware for the clip design and is provided only as a mechanical 

representation.
