In this review Frostytech is checking out an aluminum and copper heatpipe heatsink from the Japanese firm, Scythe. Scythe generally produce lower noise heatsinks and have a propensity to experiment with form and fin geometries between each generation. In other words, Scythe continually evolve their heatsink designs.
The Scythe Mugen 4 heatsink weighs 625grams and stands 157mm tall. The heatsink is built around six 6mm diameter copper heatpipes and has a footprint of 130x112mm. A 120mm PWM fan ships with the Mugen 4 heatsink that rotates at 1400-600RPM and produces upwards of 41.9d dBA according to Frostytech's real world sound measurements.
