FrostyTech posted a review on the AVC Black Samurai Heatsink

The AVC Black Samurai heatsink packs in a 120mm PWM fan which scales from 800-2000RPM, exhausting air downwards towards adjacent motherboard components like passive MOSFET and Northbridge heatsinks. Standing a good 150mm tall on six 6mm diameter heatpipes, the 760gram Black Samurai is a big cooler. For a little added visual appeal, the entire Black Samurai has been dark nickel plated.
