Taisol CCP445172 Copper Pentium 4 Heatsink Review
 |
The one-piece folded copper fin is folded and
soldered to the thick copper base. The entire heatsink then appears to have been plated with copper to provide a uniform appearance. Remember, what looks like many thin fins is actually just one piece of copper. |
There's a funny story behind this heatsink, and how it came into our hands to be tested
(Starbucks @ Las Vegas) but I'm sure you've heard that one before so let's jump right into the
review.
The Taisol CCP445172 is a full copper Pentium 4 heatsink sporting a manufacturer listed thermal resistance of just 0.329C/W and weighing in
at nearly 700grams. This is a big heatsink, and one of Taisol's newest for the 3.06GHz Intel Pentium 4
platform.
The heatsink arrived in our hands
with HSRM and metal backplate PCB support. Because the clipping mechanism is integral to the fan and fan
shroud you are pretty much stuck with a 70mm sized
fan. Some users like to drop in larger fans which can
then be operated at slower (less noisy) speeds with hopefully little reduction in overall air flow.
In this instance because the plastic fan frame plays a functional role with
the clipping system that type of fan upgrade just isn't
possible.
If you
could look closely enough at the 40 thin copper fins you would in fact find that
they are all one thin sheet
. The copper sheet has been punched out
in a particular pattern, and then folded over to form one long fin assembly.
In industry terms this type of heatsink is called a "folded fin heatsink", and
it's a technology that has been around for quite some time now.
Each of the individual fin segments are
roughly 32mm in height yielding a surprising large amount of surface area. The
thick copper base has been brazed or soldered to the entire folded fin assembly so
that heat energy is efficiently transferred - at least as long as the joints are
sound.
