4.3.4 Thermal Interface Material
Refer to Section 3.2.1.1 for general information on thermal interface material usage and
application consideration on the FC-PGA2 package.
Thermal interface material for the 3.06 GHz or higher Intel reference design is ShinEtsu* G751
thermal grease.
4.3.5 Enabled Reference Design Test Results
Table 5 represents a results summary based on internal testing of the reference thermal solution.
End users are responsible for the verification of the Intel enabled component offerings with the
supplier. OEMs, ODMs, and System Integrators are responsible for thermal, mechanical, and
environmental validation of the reference solution.
