FrostyTech has posted a nPowerTek TTIC NPH-1 Heatpipe Heatsink Review

Thermal Transtech International Corporation (TTIC) are the company behind the 'nPowertek' brand of heatsinks, and while many of you probably haven't ever heard of nPowertek, or the NPH-1 Pentium 4 heatsink we are examining, you may just want to stand up and take notice. The large blue heatsink looks fairly unremarkable from the outside, but at the center sits a 25mm diameter heatpipe which gives the NPH-1 some really serious kick. The large copper heatpipe stands 100mm tall, and comes in direct contact with the processor core for optimal effectiveness. TTIC have termed the heart of the NPH-1 a "heat column," even though it is just a very large heatpipe based on a sintered metal wick. As you know, heat pipes work by moving heat energy from one location to another, and so for the NPH-1 to work as a heatsink that thermal energy must be disposed of. Hidden behind the beefy blue aluminum shroud are 30 aluminium fins measuring roughly 70x80mm in size. The 25mm diameter heat pipe passes up through the center of each of the 0.5mm thick aluminum fins, transferring the heat energy to them in the process.
