Let’s take a look at how Gigabyte markets the system and the system specifications
according to Gigabyte

The 3D Galaxy Cooler has compatibility with all of the major CPU
sockets. Other highlights include ½ inch PVC tubing and a copper based
waterblock with a turbulence causing internal design to maximize heat transfer.
All of these design elements look to add up to a winning design. The only area
of concern is the radiator, a major cooling factor which is a 4 part/path design
and of aluminum construction. Truthfully as a cooling enthusiast myself I have
always been partial to a copper tubing/aluminum fin designed radiator which
has the best thermal characteristics. We will admit that had Gigabyte chosen
a copper/aluminum radiator the price of the kit would probably have been higher
and thus not as attractive to consumers. Gigabyte did choose to implement a
copper waterblock which is a nice to see in a retail kit as opposed to aluminum.
