Globalwin CDK38 Copper Heatsink Review
Globalwin are one of the cornerstones of the cooling industry who have always focused on
practical, high-volume production heatsink designs which offer good cooling for the price.
One such heatsink from this venerable cooling company is the little 60mm CDK38.
The fan is a 25mm thick 60mm high RPM Delta fan so the 'little' Globalwin CDK38 packs in a
big punch for a relatively small footprint. Or so we hope to see, first we have
to put this little solid copper heatsink through a few sets

So where do we begin with the Globalwin CDK38?
There are a few things which cause
it to standout from other full copper heatsinks on the market
at this moment and one of the most basic of which is its fin construction. There
are folded fin assemblies like we first saw from the likes of Neng Tyi, and
then there are skived fins which have gained so much attention this year, but the
CDK38 doesn't fall into either category.
For its fins the Globalwin CDK38 uses sheets of 0.5mm thick copper which have
been dip brazed/soldered to the base plate along their edges. There are no folded
over joints here - it is just edge of fin to base type of contacts. The joints
are really quite nice if you can look closely at them, but for our purposes it
is really more pressing that they transfer heat energy efficiently,
especially considering the relatively small 60mm footprint of which this
