Arkua 6158 Copper-Core Heatsink Review
Once you figure out how Arkua
name their heatsinks it's not too difficult to known which versions to pay extra
attention to. The Arkua 6158 is essentially the same heatsink as the 6258, but with a smaller 10mm thick fan. The lower amount of air flowing over
the fins impacts its performance level, but also yields a substantial decrease in noise. These little 60mm fans are the kind many of us were used to using on our older processors and were once the defacto standard. The all important solid copper core is still there, so you could potentially buy this heatsink and upgrade it to a 25mm or even 38mm thick 60mm Delta if you desired (and had adequate noise proofing).
I have to admit, since this is like the 83rd
heatsink we have reviewed it's kinna fun taking these close up
pics. Like the picture on the right, some really close up shots
look extra cool. If you didn't know what we were taking about it would be
hard to tag this down as a heatsink. Of course, on the practical side,
these close up pictures also help you, the consumer, get a better understanding
of the level of quality vested in each heatsinks design, and
Depending on the company, some heatsinks look like they have been
professionally made to exacting standards, and others look like they have
been thrown together, or worse yet, are just a generic extrusion with
a fancy name.
As with the 6258, the theory behind this cooler
that the more thermally conductive 29mm diameter copper core at the center will
quickly transfer the heat to the surrounding aluminum for dispersal to
the environment. The base is machined perfectly smooth, and the corners are somewhat
sharp so watch your fingers.
The orientation of the fan
is also a very important factor, and the rippled texture on the fins creates turbulence which aids
in the removal of heat energy.
The basic design of the Arkua
line of heatsinks should remind you of the Thermoengine heatsinks, and indeed according
to the Arkua website, their heatsinks are based on licensed technology from
