Scythe Katana 4 (SCKTN-4000)
Our first cooler Scythe Katana 4 (SCKTN-4000) is shipped in a small cardboard box speckled with all sorts of information as is typical of this Japanese brand.
One compartment of the box contains accessories including fasteners, screws, thermal grease, a special key and a step-by-step installation guide.
The cooler is manufactured in Taiwan and costs $29. It comes with a 2-year warranty.
The fourth Katana is still a tower but larger than the third version. The dimensions are now 143x102x100 millimeters and its weight is 480 grams. The heatsink is tilted less than before.
The key innovation implemented in the Katana 4 is the triple-array heatsink, each section having a dedicated heat pipe.
This solution helps distribute the heat more uniformly in the heatsink fins and optimize air flows, even though the resistance to the air flow is higher in this case.
Each heatsink section includes 42 aluminum plates, 0.3 mm thick, press-fitted on the heat pipes with a spacing of 2.0 millimeters.
The three heat pipes are 6 mm in diameter. Their ends are covered with figured caps. In the cooler’s base the pipes are soldered to a 38x38mm nickel-plated square of copper.
Its finish quality is perfect. Everything is reflected in it as in a mirror:
