The cooler has a fairly manageable 120mm diameter but weighs in at roughly 750 grams, not making it a true lightweight by current standards. It uses 66 aluminum fins in a radial pattern protruding from a copper core in a very similar fashion to what Zalman has been doing with their current line up of CPU coolers. The 100mm fan in the Golden Orb II spins at only 1600 RPM, but is large enough to still move a respectable 35 CFM of air. When powered up, a blue LED illuminates the pearly translucent blades giving the cooler a unique look in comparison to similarly constructed heat sinks.
