Overview of the BTX Reference Design
The reference thermal module assembly is a Type II BTX compliant design and is
compliant with the reference BTX motherboard keep-out and height recommendations
defined in Section 6.6.

Target Heatsink Performance
Table 5–1 provides the target heatsink performance for the processor with the BTX
boundary conditions. The results will be evaluated using the test procedure described
in Section 5.2.
