8 ATX Reference Thermal
Solution
Note: The reference thermal mechanical solution information shown in this document
represents the current state of the data and may be subject to modification.The
information represents design targets, not commitments by Intel.
The design strategy is to use the design concepts from the prior Intel
®
Radial Curved
Bifurcated Fin Heatsink Reference Design (Intel
®
RCBFH Reference Design) designed
originally for the Intel
®
Pentium
®
4 processors.
This chapter describes the overall requirements for the ATX heatsink reference thermal
solution supporting the processors including critical-to-function dimensions, operating
environment, and validation criteria.
.
8.1 Heatsink Thermal Solution
The reference thermal solutions are active fan solution similar to the prior designs for
the Intel
®
Pentium
®
4 and Intel
®
Core™2 Duo processors. The RCFH7-1156 (DHA-A) is
a universal design supporting the Intel
®
Core™ i7-800 and i5-700 desktop processor
series processors.
Figure 8-1 shows the reference thermal solution assembly. The heat sink attaches to
the motherboard with the push pin fastener design from previous reference designs,
see Figure B-6 through Figure B-9 for details on the push pin fastener design.
