The Thermaltake MaxOrb EX is almost an entirely copper heatsink based on a novel three-fin-segment circular design, featuring a half-dozen copper heatpipes and speed controlled 120mm fan. The radial heatsink resembles a few Zalman coolers, but the construction is completely different. Each heatpipe is given its own individual copper or nickel plated aluminum fin array, so essentially every fin is put to work evenly.
