nPowerTek TTIC NPH-101 Pentium4 Heatsink Review
have only been a handful of Thermal Transtech International Corp. heatsinks to
cross our test bench, but so far, each has performed quiet admirably. The
TTIC-NPH-101 heatsink is at first glance a fairly typical socket 478 Pentium4
heatsink, but at its center sits a 25mm diameter copper heat column. It is this
'heat column' which gives the TTIC NPH-101 its cooling power.
The large heatpipe (aka heat column)
stands 100mm tall, and comes in direct contact with the processor core for optimal thermal efficiency. The hollow copper heatpipe or "heat column," works because of a chemically coated interior surface, and not as we have presumed in the past, a sintered metal wick and working fluid.

The large heatpipe (aka heat column) stands 100mm tall, and comes in direct contact with the processor core for optimal thermal efficiency. The hollow copper heatpipe or "heat column," works because of a chemically coated interior surface, and not as we have presumed in the past, a sintered metal wick and working fluid.The heat column as it called by the manufacturer, produces similar results as that of a heatpipe, which is why we will use the terms interchangeably. The heat absorbed by the copper column of the nPowertek NPH-101 is dispersed to approximately 30 copper fins measuring roughly 70x80mm in size. The 25mm diameter copper column passes up through the center of each of the 0.2mm thick copper fins, transferring the heat energy to them in the process. A set of 70mm fans arranged in a push-pull configuration, provide the necessary airflow to remove the heat from the fins of the heatsink to the surrounding environment.

Heatcolumn heatpipes are slightly different from the standard 6-10mm diameter heatpipes we are used to seeing, and typically start off at 25mm in diameter or thicker. According to documentation by QuTech, heat column heatpipes are essentially empty cylinders of copper coated internally with a thin superconducting heat transfer medium. The copper cylinder is sealed off at both ends, and inside is under a vacuum of approximately 1 Torr.
Patent no. 6,132,823 explains QuTech's very interesting and potentially revolutionary process to the topic of heatpipes, entitled Superconducting Heat Transfer Medium . Here is a short excerpt from the patent which explains the technology in plain english, but feel free to skip ahead to the actual heatsink review.
While this heatpipe technology has surfaced on a few heatsinks we've tested already, it may be slower to adopt in spite of its otherwise promising attributes. Also, since most people would be hard pressed to explain what a heatpipe is, or does, the superconducting heatpipe, or heat column as we've taken to calling it around here, is probably going to continue to generate a lot of confusion.
