The Scythe Kozuti is composed of a nickel-plated copper base soldered to three copper heatpipes friction-fit to 57 aluminum fins. The cooler measures 110 x 103 x 40 mm (L x W x H) and weighs just 250 grams total.

The Kozuti closely resembles the Big Shuriken only smaller and with the fan placed over the base. This delivers direct airflow over the hottest portion of the heatsink, but makes it more difficult to cool down the bulky fin mass above it.

Due to the curvature of the heatpipes, there is limited space for a fan. The stock unit measures just 80 x 80 x 10 mm with hardly any room to spare.

There is a small gap between the heatsink and the intake side of the fan to reduce turbulence. The wire clips that keep the fan in place are a little loose and vibrate slightly at higher fan speeds. This is unusual as they are typically extremely secure on Scythe coolers.

Despite measuring only 110 mm long and 103 mm wide, it sports a whopping 57 fins in total. On average they are spaced 1.67 mm apart and are just 0.12 mm thick.

Cooling is provided by a nonstandard 10 mm thick PWM fan with sleeve bearings. Typically slim 80 mm fans are 15 mm thick, though they are uncommon and difficult to find.
