BIG Shuriken heatsink consists of 78 aluminum plates, each only 0.35 mm thick. They are spaced out at 1.1 mm from one another:
The copper base plate is 2 mm thick and is covered with a thin layer of nickel alloy. Its finish quality is superb:
The surface is not only mirror-impeccable, it is also very even. Both thermal compound imprints – on the glass surface as well as processor heat-spreader – turned out perfect.
Scythe BIG Shuriken has not only a bigger heatsink, but also a bigger fan. It uses 120x120x12 mm Slim Slip Stream (SY1212SL12M-P) fan:
The fan rotation speed is automatically adjusted using pulse-width modulation method (PWM) in the interval from 650 (±300) RPM to 1600 (±10%) RPM. The fan should create 15.77-38.05 CFM airflow and generate 12.91-28.89 dBA of noise. They didn’t mention the static pressure in the specs (however, I assume that a fan of such thickness with the blades of such shape should have very modest static pressure numbers). According to the specifications, the maximum fan power consumption shouldn’t exceed 2.28 W.
Scythe BIG Shuriken should be installed onto mainboards with V.T.M.S. (Versatile Tool-Free Multiplatform System) that requires no tools or any kind or removing the mainboard from the system case. Just insert the appropriate retention brackets into the special grooves in the lower heatsink of BIG Shuriken and install the cooler onto the CPU. Despite its low-profile design, BIG Shuriken cooler co-existed perfectly fine with all the surrounding electronic components and heatsinks around the processor socket…
… but it turned out incompatible with tall heat-spreaders on the memory modules installed into the first two DIMM slots (on both platforms: AMD and Intel). That is why we had to remove them:
This cooler could fit just great if we used DDR2 memory modules without heat-spreaders, but I didn’t have any at my disposal at the time of tests.
