8.1.2 Boxed Processor Fan Heatsink Weight
The boxed processor fan heatsink will not weigh more than 450 grams. See Chapter 6.0 and the

processor weight and heatsink requirements.
8.1.3 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 Celeron
processor in the 478-pin package. Motherboard
documentation should include appropriate retention mechanism installation instructions.
Note: The processor retention mechanism based on the Intel reference design should be used, to ensure
compatibility with the heatsink attach clip assembly and the boxed processor thermal solution. The
heatsink attach clip assembly is latched to the retention tab features at each corner of the retention
mechanism.
