Frostytech have tested out a compact little lower-noise heatsink from Japanese company Scythe, called the Ninja Mini! The full review is posted here.
The Scythe Ninja Mini SCMNJ-1000 is a compact lower-noise heatsink ideally suited to compact PC chassis. These diminutive PCs have until now not had much in the way to choose from for reduced noise CPU cooling. The Ninja Mini itself looks like a cube, and comes with a small 80mm fan that operates relatively quietly. Among the flurry of 120mm fan packing low noise heatsinks being released, the Scythe Ninja Mini stands just 110mm tall. It accomodates AMD K8 754/939/940/AM2/AM2+ and Intel socket 478/775 processors and weighs in at a relatively light light 580 grams.
