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.
