Retention mechanisms attach to system chassis because the Pentium II Xeon processor must have rigid support due to its weight. System design must include baseboard and chassis keepout zones and attachment locations. Consider ergonomic handling precautions, especially since units with the thermal solution attached will be heavier. They would also make heatsink removal extremely difficult. Nothing may protrude deeper into the processor.
Thermal solutions require an interface material.
Consider whether to use manual, automatic, or pre-formed dispensing. Support Components Enabling Intel has enabled several suppliers for various support components. All of these components must be incorporated in the system design prior to manufacturing.
