nPowerTek TTIC NPH-201 Socket A Heatsink
The Thermal Transtech International Corp. NPH-201 Socket A heatsink is at first glance a cooler with a rather large central heatpipe. That assessment is just about correct, except that the large column supporting its many copper fins is not technically a heatpipe as we know it. It is what TTIC have termed a "heat column." This column, 25mm in diameter and made from a hollow copper cylinder, has a chemical coating on the inside that works to the same effect as a wick in a traditional heatpipe... at least as far as we can glean from TTICs patent on the technology.
