At first sight, the Kotetsu might seem like a "mini Ashura" -  a fact which visually can hardly be denied. When looking at the fundamental concept, however, the two similar looking coolers couldn't be more different. The Kotetsu was tailored for the PC user on a little tighter budget: It has "only" four heatpipes, for fresh air a 120mm GlideStream PWM is in charge - for the heat dissipation level of the new Haswell processors this combination is more than efficient, cooling performance will not disappoint.  Despite being a budget-priced cooler, the Kotetsu is fitted with the latest H.P.M.S. (Hyper Precision Mounting System), and makes use of the "Narrow Fin" design.

Kotetsu presentation


The new Kotetsu also draws on the highly proven M.A.P.S. already having shown excellent results with the Mugen 3. Thanks to the optimized arrangement of the fins, pass-through airflow inside the heatsink is ramped up, leading to even better cooling performance.



Newly Developed Mounting System
Another new feature can be seen is the Kotetsu's new mounting system. Based on the over-the-years experience of CPU cooler mounting sytems and Scythe expertise, the kotetsu mounting was designed with the keywords "simplicity" and "reliability" in mind.


GlideStream 120 PWM
The supplied new Glide Stream 120 PWM fan with its' unique blade design is automatically controlled by the motherboard's PWM function, the temperature adjusts to the CPU.
