Thermaltake DU0462-9 Mini Copper Orb
Thermaltake have had
their Orb brand of heatsinks on the market for quite some while now, but so far
they have remained aluminum based. The mini copper Orb is a departure from that
mantra. Using the same successful cylindrical fin design with integrated fan, the
core of this heatsink revolves literally around a 25mm thick, 40mm diameter slug
of pure copper. This copper base forms the base of the mini copper orb,and makes this
heatsink one of the heavier coolers in the Thermaltake line up.
In an effort to garner some heat dispersion
to the surrounding air, the top of the large copper slug is scored with a series
of integral pegs, improving the surface area over that of what a flat surface
would have. More on the copper in a second,
let's quickly look at the specs of the DU0462-9 Mini Copper Orb.

More than just a copper slug?
Alpha were known for their copper inserts way back in the
heydays of overclocking. Those inserts were never more than a few
millimeters thick, and their impact was always hotly debated. In this case, Thermaltake use the inherent advantages of copper to better
transfer heat away from the processors core
to the top of the slug, and to the surrounding
aluminum fin structure.
The top of the copper slug is scored with
5.5mm tall, 2x2mm thick copper pegs which are separated about 1.75mm from one
another. The overall effect of these copper pegs on the entire heatsink is
curious as the manner in which the fan mounts means that a good many of them are
obscured from direct air flow. Still, extra surface area is better than a flat
Unlike just about every
other heatsink available, Thermaltake use a frameless fan which screws directly
into the base of the heatsink, which in this case is the copper peg portion. The
unique mounting means the mini copper orb has
a very low profile, but it also means there is no opportunity
for performance seekers to upgrade the fan to a higher RPM version.
If it isn't clear yet, the entire base of this heatsink, all
40mm of it is solid copper. That base has the aluminum fins press fit around it
to provide a very solid joint with good thermal transfer capabilities. If well
look closely from the side you can easily see the copper slug going through the
heatsinks aluminum fin component and coming out the other side.
The stainless steel clip, and protective aluminum shroud on the base are
mounted directly to the copper which keeps the aluminum fins about 7mm off the
The actual surface finish of the base is turned and quite smooth, and as a
plus the processor core can make direct contact with the copper if no
thermal pad is used. A small amount of silver or standard thermal compound would
