Input And Output Conditions For The Quad-Core Intel® Xeon® Processor 5300 Series Thermal Management Features - Intel X5365 - Xeon 3.0 GHz 8M L2 Cache 1333MHz FSB LGA771 Quad-Core Processor Design Manual

2.2.4.3 PROCHOT#, THERMTRIP#, and FORCEPR#
The PROCHOT# and THERMTRIP# outputs will be shared by all cores on a processor.
The first core to reach TCC activation will assert PROCHOT#. A single FORCEPR# input
will be shared by every core.

2.2.4.4 Heatpipe Orientation for Multiple Core Processors
Thermal management of multiple core processors can be achieved without the use of
heatpipe heatsinks, as demonstrated by the Intel Reference Thermal Solution discussed
in Section
To assist customers interested in designing heatpipe heatsinks, processor core
locations have been provided. In some cases, this may influence the designer's
selection of heatpipe orientation. For this purpose, the core geometric center locations,
as illustrated in
