Zalman CNPS6000-Cu Fan Heatsink Review
Zalman CNPS6000-Cu Fan Heatsink Review
Abstract: In some situations however, quiet computers are really necessary. For example, if a computer is on 24/7 in someone's room or you work in a sound studio, lots of noise is just not going to cut it.

Zalman CNPS6000-Cu Heatsink From All Angles
The Fan:

Looking down onto the 56 pairs of copper fins from the top, the center space in the CNPS6000_Cu becomes a bit more obvious. This 8mm space between the 25mm wide sets of fins is for the socket clip to sit in. It's difficult to see, but the four center fins are notched out so that the clip will sit dead-center.

The fins are bent such out from the center so they are spaced exactly 2mm from tip to tip at the circumference.

Side A:

From one the side of the CNPS6000-Cu the division looks a bit more purposeful. A stainless steel clip slides in between each of the halves and clips onto the socket with a stiff amount of force. Each of the 56 sets of copper fins are 25mm wide, 55mm tall and 0.3mm thick. Two 43mm x 2mm slits are punched out of each fin to promote better airflow. The outer fins are at an angle of 30 degrees which keeps them out of the way of any nearby capacitors, which might have otherwise get in the way. The fins can be bent out of the way if necessary however. The two screws are both stainless steel and the hole simply conserves material.

Side B:
The first thing that we noticed when looking at the CNPS6000-Cu is just how heavy the cooler is. At this angle you can see there is plenty of copper in the CNPS6000-Cu, and even though it is all very thin, each piece adds up.

Heatsink Base:

The base has been machine milled perfectly flat and is razor smooth, better than Alpha in fact. The base itself measures 41mm x 53mm. When seated on an Athlon XP, the core of the chip makes contact with the copper area which measures 17mm wide. Since the base has been milled flat only a very small amount of good quality thermal compound should be applied.
