Scythe make some good heatsinks, and the Andy Samurai Master may have a silly name but it isn't any slouch. See the full review on Frostytech.
"Design wise, the Andy Samurai Master heatsink weighs in at 685grams and comes packing no less than six 6mm diameter copper heatpipes and a 120mm 1200RPM fan. On top of that, Scythe employ a rather novel fin technique it terms the "Infinity Interleave Fin Structure". What that basically describes is a heatsink built with two different sizes of aluminum fins."
