nPowerTek TTIC NPH-1 Heatpipe Heatsink Review
nPowerTek TTIC NPH-1 Heatpipe Heatsink Review
Abstract: The heatsink looks fairly unremarkable from the outside, but at the center sits a 25mm diameter copper heatpipe which gives the NPH-1 some really serious kick.

nPowerTek NPH-1 Heatsink From All Angles
The Fan:

Looking at the top of the heatsink we can see the 25mm diameter heat column popping out. The blue aluminum fan shroud is constructed with fairly thick (1.5mm) aluminum plate, and holds everything in place. There are several cuts in the shroud to help with airflow in the heatsink I'd imagine.

Heatsink Top:
The two fans are mounted on the sides of the heatsink so air moves parallel to the 30 aluminum fins inside. The 70mm fans are mounted so that they blow in the same direction. The fans connect to a standard three-pin motherboard header, but since most motherboards only have one available for the CPU fan you will need to source out a Y-splitter of some sort. The heatsink we tested came with no such accessories.

Side A:
With the fan removed we have a better indication of how the NPH-1 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-1 features several cut outs that we can only assume have some effect on the airflow within the heatsink. The mounting system for the heatsink consists of several screws held in place with small nylon spacers. To install the heatsink you will need to remove the motherboard and screw into the supplied rear support frame. It is a somewhat cumbersome method, but the end result is a very sturdy mount that is not about to go anywhere.

Heatsink Base:

The 33mm diameter copper base consists of a 5mm thick disk attached to the remainder of the heatpipe, and provides a good mounting point. The copper is very flat, and very smooth, so only a small amount of thermal compound is really necessary. Note the small white plastic screws and spacers at each corner of the base which are those used to secure the NPH-1 to the motherboard.
