The new Big Shuriken's cooling proficiency is excellent, particularly at low noise levels. With the original Big Shuriken, a huge 15°C drop-off in performance was experienced going from 1100 to 800 RPM, but the difference was only 5°C for the revised model. The heatsink's capabilities improved even further when paired with our reference Nexus 120 mm, but it was hardly a fair fight; a standard 120 mm fans like the Nexus is twice as thick, increasing the total height of the cooler to 71 mm.

Hardly surprising, the diminutive Vanxie performed 20~30°C worse than the Big Shuriken at comparable noise levels. Even at maximum fan speed, it couldn't keep up with the Big Shuriken at its lowest tested fan speed. It couldn't keep the CPU properly cool at ultra low noise levels either, approaching the chip's throttling temperature (~98°C) at 7V / 14 dBA@1m and exceeding it at 6.5V / 12 dBA.

Thanks to improved low airflow performance, the new Shuriken surpasses the original by a comfortable margin in our performance chart, even beating out the much larger Samurai ZZ. Equipped with our reference Nexus 120 mm fan, it is almost on par with the Noctua NH-L12. A standard sized fan increases the height of the Shuriken to 71 mm though, 5 mm taller than the NH-L12 when the Noctua is configured to use one fan in the bottom position blowing downward.
Though similar in size, the Reeven Vanxie can't touch the Scythe Kozuti, trailing by double digits at similar noise levels. It's also the first cooler we've tested on our new small CPU heatsink test platform that couldn't keep the processor from throttling while producing 12 dBA@1m. An overclocked 95W quad core Sandy Bridge is a bit much for the Vanxie's capabilities.

VRM cooling is also much better on the Big Shuriken 2 Rev. B than the original, but only when comparing the stock fans. The first Big Shuriken actually performed a bit better when both heatsinks were paired with our reference fan. The Vanxie came in last as one would expect.
