TTIC NPH-201 Heatsink From All Angles
The Top:

Looking at the top of the heatsink we can see the 25mm diameter heat column popping out, and covered with a red plastic cap. The anodized aluminum fan shroud is constructed such that it only attaches to the base plate. It holds the 70mm, and 80mm fans about 4mm away from the edges of the copper fins.

Heatsink Detail:
Each fan is mounted on one side of the NPH-201 heatsink so air moves parallel to the 30 or so copper fins. The fans are mounted in a push-pull configuration, and each connect via a standard three-pin motherboard header. The copper fins are 0.2mm thick and spaced about 2mm apart. The fins are also cut with a leaf pattern to lessen resistance at specific points.

Side A:
The 80mm fan intakes air, and blows it across the copper fins and heat column. The 70mm fan is set up to pull air from the cooler and exhaust it outwards. Since the sides of the heatsink are left open, there should be little problem with back pressure.

Side B:
From this angle we can get a better view of how the 70mm and 80mm fans are arranged. Since the sides of the NPH-201 are open, air can move in and out of the heatsink as pressure dictates. The lower 20mm height of the column is free of fins to provide clearance for the three-prong socket A clip to move.

Heatsink Base:

The base of the copper heat column is 32mm in diameter, and consists of a 5mm thick disk of metal. It provides a good mounting point for the core of the AhtlonXP processor, and is pretty flat. The metal frame of the heatsink is attached directly to the base of the central copper column, and offset for a perfect fit on those small silicon core's of the Athlon.
