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.

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. There are two designs being
enabled. The first is called RCFH7-1156 (DHA-A) which is a universal design supporting
the Intel
®
Core™ i7-2000 and i5-2000 desktop processor series (Quad Core 95W). The
second is called the RCFH6-1156 (DHA-B) which only supports the Intel
®
Core™ i7-
2000 and i5-2000 desktop processor series (Quad Core 65W) and Intel
®
Core™ i3-
2000 desktop processor series (Dual Core 65W).
The two solutions are very similar. They both use an approximately 25 mm (1 inch) tall
aluminum extrusion, integrated fan and molded plastic housing. The notable difference
is the RCFH7-1156 has copper core to support the higher TDP as compared to the
aluminum core of the RCFH6-1156. Theses designs integrate the metal clip used in
prior reference designs into a molded assembly that includes the fan motor housing
and wire guard.
shows the reference thermal solution assembly. The heat
sink attaches to the motherboard with the push pin fastener design from previous
reference designs, see
for details on the push pin
fastener design.
