Conclusions:
There is a lot to like
about the new Kingwin heatsinks. There is a style to fit most
tastes and all of them come in with prices that place them in the middle
of the pack. As with any full line of products, we found some we
really liked and some that we would pass on to others but you can't go
wrong with any of these products if you plan your build correctly.
Using the DFI motherboard
may have added an additional layer of challenges for the Kingwin
heatsinks to overcome. The CPU socket sits at a 90 degree
orientation compared to today's most common designs and so the memory
sits across the top as opposed to the front edge. Still this does
bring to light the importance of carefully checking the motherboard
clearance before placing your order. We were able to get each
design to install even with the DFI quirks with some minimal
rearranging. The install method does make me wonder what the
Kingwin definition of "Ease of Install" means! All of the Kingwin
heatsinks required a motherboard removal to install. Because the
AMD socket install used the factory mounting holes, it would have been
much easier to design the brackets to use the factory backplate and make
the installation a quick swap. This design decision may have been
required to accommodate the universal support but the weight of each
heatsink could have been supported by a factory bracket but, no one likes
pulling a motherboard.
Taking the line as a whole
I found the KA-9227 to be the favorite with a fun look and performance
to back it up! The KA-9225 and KA-9226 are both great looking products
that will find good homes in builds with a less needy CPU or a case with
solid airflow. (AMD and Intel both have improved on heat issues
substantially since the Opteron processors arrived on the scene).
The KA-9228 is a solid performer with a more traditional style that
would be a fantastic choice for a less showy build thanks to its
versatility and fan upgradeability. All of these units will become
even better deals as the prices come down in the after market as well.
I would like to thank
Kingwin for the opportunity to take a look at all their new offerings!
