When AMD announced their K8 CPUs, everyone, including myself, searched long and hard for better thermal solutions. Swiftech was quick with their release of the MCX64-V and MCX6400-V. The MCX64-V was aimed for the mainstream enthusiast. It met AMD's thermal and weight specifications and provided great cooling over the stock cooler. The MCX6400-V was released for the enthusiasts. It features much more pins and a thicker copper base. It has been quite some time since the release of the MCX6400-V. Today, we see whether it is still a viable choice for enthusiasts.
