A Closer Look

Scythe's Ninja 5 sports six Ø6 mm heat pipes that transfer heat from the CPU to the forty-one aluminium fins and the black top plate. Of the forty-one fins, six are cut back for memory clearance. In regards to its design, the heatsink is a large monolithic design rather than the more typical dual-tower design, at least on the surface. Upon closer inspection, users will find it is indeed a dual-tower design; however, the two towers are connected diagonally, weaving over each other. It is an interesting design, to say the least.


In terms of weight, the Ninja 5 tips the scales at 1190 g including the fans, which makes it one of the heavier coolers on the market. Thanks to its square design, it will also block a large area around the socket. Suffice it to say it is definitely a brute.


The heat pipes are arranged in a typical U-shape that enters the fins in an offset manner to better transfer heat over a larger surface area. Meanwhile, the top plate being black gives the cooler a touch of class that should allow it to blend in, unlike the Ninja 4 and its plain aluminium top plate. Thus, the cooler's "Ninja" moniker is a better fit with this revision since it now looks the part.


The Scythe Kaze Flex fans have a PWM range of 300–800 RPM and feature a sealed fluid dynamic bearing. Featuring a mean time to fail (MTTF) of 120,000 hours, users can expect great longevity and ultra-low noise levels.
