Like many of Thermaltake's cooling products lately, the DuOrb is packaged in a snap-apart clear plastic clam shell inside a colorful box with cutouts to show off the top and bottom of the cooler. Along with the cooler we get an accessory box containing mounting clips for AMD AM2/AM2+ and Intel LGA775 sockets, an alternate AM2 backing plate and instruction sheet. The instructions depict a few diagrams of each installation type, AMD and Intel, as well as a special insert for AMD owners whose boards may have the CPU socket oriented 90 to the PCIe slots.

The DuOrb is not much wider than its base in the area between the orb sections, however the overall spread of the wingspan is quite long, just over 200mm or around eight inches. The six copper heatpipes are split three into each orb, with one of the pipes traversing the outer copper fins with the other two circling the inner aluminum fins. There appears to be plenty of height above the base in order to clear surrounding components such as memory but we'll find out for sure once we go to install it.

Unlike the VGA DuOrb, the fans used here do not have the same S-shaped blade design, but rather use a more traditional configuration incorporating 11 curved blades for quiet, low speed operation with decent airflow. They are supported over the fin array by a bracket connecting them directly to the base and not adding weight to the heatpipes, which are soldered to each individual fin. The single 3-pin power lead is sleeved in a rubberized coating and offers a signal wire for monitoring fan speed via the motherboard.

The base is actually made of two halves, the bottom copper and the top aluminum, sandwiching the six heatpipes between them. Screws used to attach the fan bracket to the base also hold the two sides together, although there is most likely solder or some other compound used in between the layers to assist heat transfer from the base into the pipes. The bottom of the copper base is reflective but not a perfect mirror finish. There are some residual machining marks present, although not likely to be detrimental to performance.

Next let's install the Thermaltake DuOrb and see how it fits.
