Scythe Ninja 4 CPU Cooler Review: All Hail the Kingslayer

If at first you don’t succeed, try, try, try again. Nobody gets things right the first time and even if done well, needs change over time so a revision is almost always guaranteed to happen. It is not about striving for perfection because what that is cannot be a clearly defined point, but it can be approached. This is a proverb cooling product manufacturer Scythe has also taken to heart with their Ninja CPU cooler series.

The Scythe Ninja 4 is the latest iteration of the company’s symmetrical tower-heatsink design. Utilizing six 6mm heatpipes arranged in U-formation, the Scythe Ninja 4 actually has less heatpipes than its predecessor which had eight but boasts a refined aluminum fin structure that promises to be much more efficient especially at lower fan speed levels. Bundled with the Scythe Ninja 4 is a 120mm Glidestream 120mm PWM fan with an adjustable 3-level fan speed switch for those with non-PWM headers, allowing for 1500, 1150 and 800 RPM speeds.

Before you take to Tumblr and accuse Scythe of insensitivity and cultural misappropriation for its product naming and packaging, keep in mind that Scythe’s headquarters is actually in Japan; originally from Akibahara, a district known around the world for their electronic stores. Besides, it is in a rather playful context so put down that pitchfork and do not be such a baka desu.

 

The packaging internally itself is modest with the heatsink held in place with cardboard and the accessories housed in its own box on the top. Any decent heatsink should be ready for installation right out of the box and that is exactly what Scythe has with the Ninja 4 as there is bundled thermal interface material as well as a mini hex spanner and screw driver with the mounting kit and illustrated user guide. An extra fan mounting clip is provided as well for an optional secondary 120mm fan.
