Scythe is acclaimed as one of the top air cooler manufacturers, and for good reason, with its products remaining on the top spot for air cooling efficiency long after they've first been introduced. For such a company, the addition of another product to their lineup would be expected to be an affair of toiling trumpets and performance promises, but this has not been the case. Scythe seems to have elected to go for the "powerfully silent" path for the Sengokubune tower cooler, stealthily adding it to their Japanese product pages.
The Scythe Sengokubune is a tower cooler with 156 mm height, which should make it compatible with most mid-tower cases, and makes use of the common stacked fins design that's preferred for this type of cooling solutions. Each fin is a "shi ship", which aids in airflow and smoother heat dissipation throughout the stack, while reducing turbulence. There are 6x 6 mm heatpipes to draw heat from the base-plate, though they aren't of the direct contact design type. The heatpipe's asymmetrical design should enable users to keep clearance priorities in play, with the cooler orientation defining wether more clearance space is given to the memory modules or graphics cards.
The Scythe Sengokubune weighs 500 g, and brings with it a 120 mm, oil-bearing fan whose speed interval stands at 400-1400 RPM. Noise is being quoted at the 12.0 ~ 27.85 dBA interval, while air volume stands at 37.2 ~ 68.42CFM. Pricing wasn't available at time of writing, though the cooler should be relatively quick to reach the Western markets.Sources: Reddit, Scythe
