Blizzard S370 Copper Heatsink Review
Like its' brother the S370-L, the Blizzard S370 sports a set of thick copper fins, and a solid copper construction.
Armed with a much more powerful Sanyo Denki fan this copper heatsink promises some very sweet performance characteristics.
There are a couple of points which make
this model stand out from the S370-L we looked at previously. First off, the
S370 is not angled in the manner the other Blizzard was, but rather the fan sits
in a pure impingement orientation. While this is a relatively heavy
copper heatsink, it is not nearly in the same league as the MC462A
As always, the question we try to answer is
how well this heatsink stacks up against our set of reference coolers. So let's
AMD Athlon, Duron, K6-2. Intel FC-PGA, PGA.
VIA Cyrix III.

The first thing we
noticed about the S370 is how it was made. Each of the fins has been stamped out
from a 1.5mm thick sheet of copper. The 16 fins
are then matched up with grooves cut into the ~3mm thick
base. The fins and the base are joined into one solid mass by soldering the
fins to the base. A few special clips bring the tips of
the fins together so that the fan can be screwed into place.

It is always important to have two things
that can be said about the finish of a base. First, that the base is flat, and
second, that the base is smooth. Having one without the other is better than
neither, but the true test of a good heatsink is having both. In the case of the
Blizzard S370, the base is very smooth, but not perfectly flat. If you notice
the very slightly wavy line at the top of the image below, that will give you an
idea as to the level of flatness on the S370.
Note the slight waviness in the
