As the speed from CPU's has grown, so has the amount of heat generated requiring an evolution from the once passive heatsink to an active form. Over the years, as the heat increased, so did the size of the HSF to compensate. Different materials and ever increasing fan speeds all helped to reduce temperatures with HSF's becoming larger and in most cases louder.
Along the way designers and engineers sometimes made additional changes to the basic premise of the HSF in an effort to gain an extra foothold in the fight against CPU heat. The most common addition right now is the heat pipe which has allowed manufacturers the possibility of reducing fan speeds without compromising performance. What we are about to look at today is something similar but expands on the idea somewhat. Ok, let's get right in there and see how the technology of our review item, the , functions and performs.

Yes, a technology section for a CPU Cooler. The main technology used on the Deep Impact cooler is what is a sort of Superconductor, with the heat being transferred to the central stem of the cooler ready to be cooled by the surrounding fins. The Supertube used here has a wide range of applications, and is something that has been researched at length.
How this works is as the name suggests heat is conducted straight into the stem, which is filled with various chemicals and then vacuum sealed. The chemicals form 3 basic layers inside aimed at delaying corrosion and oxidation. Like the heat-pipe technology used by CoolerMaster and others, as the inorganic liquid compound inside is heated, it becomes a gas which then rises to the cooler parts. As it is cooled it returns to a liquid once again and moves to the hotter parts to start the process all over.
So just how efficient is the Supertube? When it comes to metals, silver is the best conductor with silver pushing 10.312 K (watts/inch C). The Supertube on the other hand is capable of 72.184 K (watts/inch C) which even beats diamond at 16.000 K (Just for reference copper sits at 9.7790 K). Naturally, silver and obviously diamond are too expensive to use in this sort of application but the Supertube is lot easier on the wallet. How well this will equate to CPU cooling we shall discover later.
Ok let's have a look at the package.
