nPowerTek TTIC NPH-101 Pentium4 Heatsink Review
Abstract: The large heat column stands 100mm tall, and comes in direct contact with the processor core. The hollow copper heat column works because of a chemically coated interior surface.

TTIC NPH-101 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 the two 70mm fans in place.

Heatsink Top:
Each 70mm fan is mounted on the side of the heatsink so air moves parallel to the 30 or so copper fins inside. The fans are mounted in a push-pull configuration, and connect via a standard three-pin motherboard header. The copper fins are 0.2mm thick and spaced about 2mm apart.

The TTIC NPH-101 heatsink uses some captive screws in the base plate to screw into a special metal motherboard support plate that comes with it. When installing the TTICNPH-101 heatsink, you will first have to remove the motherboard, take off the standard Intel Heatsink retention frame, and then install the heatsink and its custom metal support plate. This makes installation rather cumbersome, and detracts greatly from the generally impressive cooling figures this heatsink is capable of producing.

Side A:
The aluminum frame holds the fans in place, and is attached to the stainless steel base plate. Some vents have been punched into the side of it to aide airflow over the copper fins.

Side B:
Both fans are 15mm thick, and 70mm in size. There is about 3-4mm space between the rear of the fan, and the copper fins. Curiously, there are no fins by the base of the heat column.

Heatsink Base:

The base of the copper heat column is 33mm in diameter, and consists of a 5mm thick disk. It provides a good mounting point for the IHS of the Pentium 4, and is pretty flat, and sufficiently machined smooth. The stainless steel base plate is attached to the central copper column, and the four mounting screws are held in place with little black plastic stand-offs to ensure the heatsink remains at the correct height when installed.
