Zalman CNPS5700D-Cu From All
Angles |
 |
The Fan:
The fan duct is
pretty big, and directs the warm exhaust air from the heatsink to any
direction you
like since it swivels. The point though is to direct that
exhaust towards the rear case fan and get it out of the computer as quickly as possible. The fan hooks up to the motherboard via a 3-pin fan header or it can be connected to Zalman's fan mate one to
make the cooler run under silent operation. |
 |
Top: The central spring holds the copper heatsink
which forms the heart of this cooler in place. The entire frame clips into
the heatsink retention mechanism, and the single clip is what applies the
force to the copper fan section, and in turn the processor core. The fins (of which there are
lots) all all copper and measure about 0.2mm thick. The heatsink only accepts 80mm fans, or fan
adaptors. |

Side
A: Looking from the front
and the back you can get a good idea of the scale of the fan duct. It is
literally about the size of the entire heatsink, and this is important. The fan duct works well directing the exhaust air, and actually improves cooling when installed by a very slight amount.

Side B:
Here again
we can see just how large the air duct really is on
the CNPS5700D. The heatsink measures 150mm high, so if you have very thin case chances
are that this heatsink may not fit entirely. The top of the air duct sits substantially
higher than the top of PCI or AGP card for example (by about 50mm roughly). |
 |
Heatsink Base:
The copper portion of the base of the CNPS5700D
measures 30mm by 38mm. The finish on
the base is really good as is the case with every Zalman heatsink we have
tested to date. Since the manufacturing process involves joining many thin pieces of copper
together it is necessary to mill the base flat. The results are razor smooth and that means
only a small amount of good quality thermal compound should be used. |
