nPowerTek TTIC NPH-2 Heatpipe Heatsink Review
nPowerTek TTIC NPH-2 Heatpipe Heatsink Review
Abstract: The first Thermal Transtech International Corp. heatsink we tested performed quiet admirably, and so it is with high expectations that we look upon the Socket A NPH-2 model

nPowerTek NPH-2 Heatsink From All Angles
The Fan:

Looking at the top of the heatsink we can see the 25mm diameter heat column popping out. The anodized aluminum fan shroud is constructed with fairly thick (1.5mm) aluminum sheet metal that holds everything in place.

Heatsink Top:
The 70mm fan is mounted on the side of the heatsink so air moves parallel to the 30 or so aluminum fins inside. The fan connects to a standard three-pin motherboard header.

Side A:
With the fan removed we have a better indication of how the npowertek NPH-2 heatsink is built. The central 25mm thick heatpipe column acts as a post for the aluminum fins to be pressed on to. In this way, the aluminum fins have direct contact with the copper heatpipe and can easily absorb and disperse the heat energy it absorbs from the processor. Fins are 0.5mm thick and spaced about 2mm apart.

Side B:
The side of the NPH-2 is plain, and simply ducts airflow within the cooler. It may have proven a little more effective to have the fan shroud actually meet the fan, as we notice a lot of airflow escaping along the side. The clip mechanism at the base is tool free and pretty easy to use.

Heatsink Base:

The 33mm diameter copper base consists of a 5mm thick disk of copper attached to the remainder of the heatpipe, and provides a good mounting point. The copper is flat, and pretty smooth, so only a small amount of thermal compound is really necessary.
