The
initial performance numbers on the Globalwin CDK38 are pretty good for its small
60mm footprint. With numbers like this you might be able to use
this heatsink
in small cases, as long as the airflow to and from
the fan is not cut off by errant wires or cables. The fan grill
will protect the fan from inhaling a finger or molex connector, but if wires just
end up sitting on top of the fan's intake a problem will occur.

The overall performance of the all-copper Globalin CDK38
looks pretty good. With that nice powerful 7000RPM fan all brazed copper fin to
copper base construction the heatsink appears to make a very good, and very
compact heat exchanger. The weight of the CDK38 is not too bad, but with any
pure copper heatsink it is always a smart idea to remove it from the computer
during shipping. Since the heatsink uses only on of the sockets clips to attach itself there
is a good possibility that a fatigued socket clip could snap off under applied stress.
Noise is an issue with this heatsink, but the main reason it was able to
achieve such high thermal scores is because of that fan. The CDK38 may have been
originally designed a while ago, as the trend in heatsinks right now dictates
that low-noise is the best solution. Still, if you are looking for something
small and speedy, the Globalwin CDK38 might just be your ticket to
fame.
