Dynatron DC1U-B01 1U Copper Heatsink Review
Dynatron's all copper DC1U-B01 Socket A heatsink is
designed for use in 1U server environments, but, does it have the right stuff?
We've tested hundreds of heatsinks and only handful have ever used
squirrel cage fans because of their low CFM ratings. Has Dynatron figured out the
secret to making the worlds best 1U socket A heatsink, or are we looking
at something which just makes the grade?
Read on and you'll find out those questions and many
more! First off, lets have a look at the heatsink itself and consider that 1U servers only leave about
30mm worth of vertical space for the entire cooling package; that means heatsink and fan.
Ensuring that the total thermal solution will work within the limits
set out by processor manufacturer usually means that with the size limitations,
1U heatsinks always test hotter than standard desktop coolers. This isn't to say they run that hot in the
server as forced air usually adds a degree of cooling we just can't factor in.
In any case, the Dynatron DC1U-B01 is set for some
competition from a few other Socket A 1U server heatsinks.

You
will be hearing us mention the work "skive" quite a
lot in this review, and if you aren't familiar
with the term there is no need to fret. 'Skiving' is a manufacturing process by which
the copper fins of the heatsink are drawn up from a
flat plate or
bar of copper to form the final heatsink.
The remains of that flat
plate go on to form the base of the actual
heatsink. The significance of this set up is that
there is no interface to be concerned with between the fins and base. Materials such as
solder, or thermal epoxy can impede the flow of heat energy
more so than
pure copper. Skived heatsinks make those concerns obsolete.

Air is drawn in
from either side of the heatsink, up through the fan and then exhausted outwards. A standard vaneaxial
fan would intake air from the top and exhaust it out through the heatsink
to either side. We'll have to wait until the thermal results are in
before we know if Dynatron's technique will pay
off. |
