ClubOC has just posted a review of the Vantec CCK-6027D HSF for you. let's see their take on the little brother of the 6035 model. here's a snip:
"Just like it's bigger brother, the -6027 uses a solid copper base and the thin copper fin design. The outer case of the HSF serves to direct air and supplies the mounting points for the 60mm fan. The outer case of the HSF is actually made from Aluminum, but coated copper."
