[On a side note, I think Thermalright are a little gun shy of Frostytech - doesn't look like we'll be testing out the Thermalright True Copper heatsink any time soon.]

Thermalright is just talking about the "True Copper”. But however it is called: IT is the full copper version of the successful Ultra-120 Extreme, which became available in a "True Black” version only recently. Thus Thermalright offers the cooler in three versions that differ in material and color.

Copper monster in detail The cooler transfers the heat of the processor via six pipes to the soldered fins. Not only the CPU plate and the heatpipes, but also the fins are made of copper - like on the Scythe Ninja Copper. Because of this the whole devices weights 1.9 kilograms - twice as much as the "normal” Ultra-120 versions. As usual a fan is not included, but fittings for the sockets 775 and AM2 are. With an appropriate kit it is possible to mount the True Copper on socket 1366 Nehalem systems. The fastening with its four screws and the backplate is very tough and keeps the copper block firmly attached to the board - but you shouldn't move the system that much.
