3.3 Reference Solution for the Intel

Pentium

Processor in the 478-Pin Package

Note: The thermal mechanical reference design for the Intel

Pentium

4 in the 478-pin package has

been validated according to the Intel validation criteria given in Section 3.1, and using all the

reference components as described in this document along with the reference thermal mechanical

enabling components for the chipset. Any thermal mechanical design using some of the reference

components in combination with any other thermal mechanical solution needs to be fully validated

according to the customer criteria. Also, if customer thermal mechanical validation criteria differ

from the Intel criteria, the reference solution should be validated against the customer criteria.

3.3.1 Components

Figure 19 shows an exploded view of the Intel reference solution for the Intel Pentium 4 processor

in the 478-pin package. This reference solution consists of: heatsink, fan, fan shroud, thermal

interface material, heatsink clip, retention mechanism.

Note: Intel reserves the right to make changes and modifications to the design as necessary.
