| Zalman CNPS7000A-Cu
Heatsink From All Angles |
 |
The Fan:
The fan Zalman
use with the CNPS7000A-Cu is 84mm in diameter, and about 25mm tall. Rotating at 2400RPM, the
fan moves air without creating a lot of noise. The fan connects via a
standard three pin motherboard header which supports RPM
monitoring. Zalman's Fanmate 1 can be used to further decrease the speed of motor for even quieter operation
if desired. Decreasing the speed of the fan will impact on the heatsinks performance by a
certain degree since less air is moving over the copper fins. |

Heatsink Top:
With the fan and spring clip mechanism
removed we can see the CNPS7000A-Cu for all it is worth. The entire
heatsink is made from an assembly of individually punched out sheets of
0.4mm thick copper, the assembly is then squeezed together under high
pressure and bolted tight. The central base section is ~26mm wide, and
from tip to tip the heatsink measures approx. 110mm x 110mm. It looks
circular, but is more oval shaped really. The cut out in the center of the
base section is for the clipping mechanism which applies pressure at the center of
the heatsink. |

Side A:
From this side we can see just how
the
copper fins gradually
come together to form the body of the heatsink
itself. Compressed under high pressure the fins come into perfect contact at the base which
is then machined absolutely flat and smooth. The bevel in the shape of the
heatsink is so it will clear the HSRM, and any capacitors placed near to the
socket. |
 |
Side B:
Standing 62mm high, the CNPS7000A-Cu is fairly compact
all things considered. Most heatsinks have the fan mounted on top of
the fins which
can raise the overall height of a cooler to well over
80mm. The copper fins are spaced about 1mm apart at the outside edges. The spring clipping
system is mounted to the heatsink in such a way that there is no chance of
play. |

Heatsink Base:
If you ever wanted to see the example
of a perfect heatsink base finish look no further than the
Zalman CNPS7000A-Cu... Milled perfectly flat, there are no machining marks visible - the
surface is very flat and smooth, but not polished. The little aluminum blocks are
used during the compression process to help apply even pressure, and for
the mounting hardware to attach
to. With a base finish
of this calibre, only a very small amount of good quality thermal compound is necessary. Also
note the two sets of holes in each side of the mounting clip, the inside
holes are for a P4 mounting system, and the outside for
Athlon64/AthlonXP. |
