A new heatsink review from Frostytech, check it out!

"The thermal design follows in the footsteps of models released by Xigmatek and others, but if you flip the Blue Aurora AK-966BL over you won't find exposed heatpipes. The Akasa Blue Aurora AK-966BL is equipped with a 120mm PWM fan which scales from 500-1500RPM and is internally illuminated with a few blue LEDs. The roughly 625 gram heatsink is compatible with socket 775 Intel Core 2 Duo/Quad processors, and stands a respectable 150mm tall."
