There are a couple aspects that go into making the Zipang 2 unique, but let's start with the basics. The Scythe Zipang 2 (SCZP-2000) heatsink features six 6mm diameter copper heatpipes, "multiple airflow pass-through" aluminum fins, a copper base plate and a mammoth 140mm PWM fan that spins at a leisurely 1000 RPM. The heatsink weighs in at 715 grams and stands just 105mm high. That squat height means it competes well against the multitude of +150mm tall tower heatsinks which are too big for a great many PC cases out there. The fan has 11 impeller blades and is rated for 51.4 CFM.
