The Scythe Ninja Cu (test) was a revised version of the Ninja in full copper casing with a new fan that provided better cooling at a lower sound pressure level. At 60 euros, the version, which was limited to 600 copies in Germany, was more expensive than many of its competitors – and heavier.

Copper as far as the eye could see
With dimensions of 110 × 110 × 150 mm (L × W × H), the cooler weighed around 1,120 g. The high weight was due to the change in material – the original made of aluminum weighed 665 g. As with the original, Scythe uses a six-way U layout with 6 mm heat pipes that dissipate the waste heat from the copper base plate to the copper fins. Unlike the original version, the heatpipes were spaced slightly further, distributing the heat more evenly.
With its 23 wafer-thin fins and their relatively large spacing of about 4 mm, the Scythe Ninja was optimized for low-speed fans. The included Scythe Slip-Stream fan (120 mm) worked at a maximum of 800 rpm. With this, the manufacturer went back to its roots: silent cooling. Even at full speed, the fan was hardly audible, when throttled it was completely inaudible.
Outstanding in silent mode, even with reference ventilation
To ensure a fair comparison between the coolers, 15 years ago all coolers were tested with three different reference ventilations. The Scythe Ninja Cu was able to stand out particularly in the Super Silent configuration. He achieved slightly better results with the series ventilation than with the reference fan. In both cases, however, it placed itself at the top of the test field, right after the Thermalright IFX-14. In the other two fan configurations, the values were a bit worse compared to other coolers, but it was always enough for a place in the middle. At high speeds, the large distances between the fins thwarted the Ninja Cu – the cooler was developed explicitly for slowly rotating fans.
Super-Silent -configuration [< 31 dB(A)]
Quiet to medium configuration [< 40 dB(A)]
Power Configuration [> 40 dB(A)]
Overall, the Ninja Cu was a successful cooler. With a price of 60 euros, the limited edition was comparatively expensive. In addition, the dimensions and the high weight of the cooler meant that it could not be easily installed in every case. Especially when mounting on Intel systems, there were some difficulties due to the sheer size of the cooler. With only 600 copies on the German market, the Ninja Cu was a model for enthusiasts.
