If someone was to ask you to name a heatsink manufacturer, I'd be willing to bet that Scythe would not be the first name that comes to mind. While not new to the scene, Scythe is still a relatively unknown name in the enthusiast market. This is unfortunate because as you have seen in past reviews of a few of Scythe's coolers, every one has performed extremely well. Today I am going to take a look at another of their coolers aimed at the enthusiast market, the Katana Cu. Let's see if this new all copper version of the Katana can help put the name Scythe, on the minds of more people.
