Design Information  
5.1 
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 
The solution comes as an integrated assembly. An isometric view of the assembly is 
provided in Figure 
5-4.  
5.1.1 
Target Heatsink Performance  
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 
The table also includes a T
A
 assumption of 35.5° C for the Intel reference thermal 
solution at the processor fan heatsink inlet discussed in section 
3.3. The analysis 
assumes a uniform 35° C external ambient temperature to the chassis of across the 
fan inlet, resulting in a temperature rise, T
R
, of 0.5° C. Meeting T
A
 and 
CA
 targets can 
maximize processor performance (refer to Sections 
4). 
Minimizing T
R
, can lead to improved acoustics.
