NOTES: In the case of a discrepancy, the most recent processor datasheet supersedes targets listed in the
above table.
1. These specifications apply to uniform compressive loading in a direction perpendicular to the IHS top
surface.
2. This is the minimum and maximum static force that can be applied by the heatsink and retention solution to
maintain the heatsink and processor interface.
3. These parameters are based on limited testing for design characterization. Loading limits are for the
package only and do not include the limits of the processor socket.
4. This specification applies for thermal retention solutions that allow baseboard deflection.
5. This specification applies either for thermal retention solutions that prevent baseboard deflection or for the
Intel enabled reference solution(COOLING SOLUTION).
6. Dynamic loading is defined as an 11 ms duration average load superimposed on the static load
requirement.
7. Experimentally validated test condition used a heatsink mass of 1 lbm (~0.45 kg) with 100 G acceleration
measured at heatsink mass. The dynamic portion of this specification in the product application can have
flexibility in specific values, but the ultimate product of mass times acceleration should not exceed this
validated dynamic load (1 lbm x 100 G = 100 lb).
8. Transient loading is defined as a 2 second duration peak load superimposed on the static load requirement,
representative of loads experienced by the package during heatsink installation.
