Intel Pentium 4 Processor in the 478-PinPackage at 1.40 GHz, 1.50 GHz, 1.60 GHz, 1.70 GHz, 1.80 GHz, 1.90 GHz, and 2GHz

Boxed Processor Specifications
Datasheet 89
8.2.2 Boxed Processor Fan Heatsink Weight
The boxed processor fan heatsink will not weigh more than 450 grams. See Chapter 6.0
and the Intel® Pentium® 4 Processor in the 478-pin Package Thermal Design Guidelines
for details on the processor weight and heatsink requirements.
8.2.3 Boxed Processor Retention Mechanism and Heatsink Attach Clip
Assembly
The boxed processor thermal solution requires a processor retention mechanism and a
heatsink attach clip assembly, to secure the processor and fan heatsink in the baseboard
socket. The boxed processor will not ship with retention mechanisms but will ship with the
heatsink attach clip assembly. Motherboards designed for use by system integrators
should include the retention mechanism that supports the boxed Pentium 4 processor in
the 478-pin package. Motherboard documentation should include appropriate retention
mechanism installation instructions.
