Scythe Rasetsu CPU Cooler Review


Scythe's Rasetsu is their second model to utilize their Trident Multi-Layer Fin technology, and this time comes in a top-flow model which is capable of high performance cooling in even low clearances.


Scythe's Rasetsu utilizes their innovative Trident Multi-Layer Fin (T.M.L.F.) structure, which helps minimize static pressure stagnation, and also claims to increase airflow over the fins themselve over conventional "wall" type fins.  It also has a space between the fins and the fan itself, which minimizes the dead airflow space directly behind the fan motor as well.  As I reported while reviewing Sycthe's first cooler to use this technology, the Yasya, the T.M.L.F. fin structure really looks awesome, and Scythe's beautifully lustrous Nickel-Plating really tops their coolers off in the aesthetics department.  There is always something beautiful when form and function meet and run hand-in-hand, and Scythe has certainly found a way to make this union once again with Rasetsu!


The Scythe Rasetsu Six Heat Pipe Trident Multi-Layer Universal CPU Cooler is a universal CPU solution featuring Trident Multi-Layer technology. By placing the number of triangle shaped main & supplemental heatsink fins in position to maximize the air intake volume, the heat absorb rate from the built-in heatpipes becomes ideal for extreme over-clocking purposes. The Scythe Rasetsu cooler comes stock with the Scythe Slip Stream PWM Fan which allows it's user to choose the fully automated fan speed control that is installed in an open PCI slot. This lets the user control the overall range of PWM functionality.
