The V10 CPU cooler is so great because it has a TEC (Thermal Electric Cooler), also called a Peltier element. A Peltier element has a hot and a cold side, and uses thermoelectric properties to move heat from the hot to the cold side. It is pretty cool tech, if you will pardon the pun, but rather complicated to anyone without a background in physics or, more specifically, electical engineering. If you are up for it, there is a lengthy and technical, but good, explanation of Peltier cooling here.
The cold side of the element is connected to six heat pipes that connect to the CPU base, which has a special nickel coating with a copper core. Four more heat pipes are dedicated to directing the heat of the back (hot side) of the Peltier element away. Thats a total of ten heatpipes for the appropriately named V10, six cooling the CPU, and four moving heat away from the cooler towards the case's airflow. As one would expect from this, the V10 CPU cooler is huge. Make sure you look at the dimensions before deciding to buy it.
