In this review Frostytech is testing Auras' lower noise Shagon AHC-118 tower heatsink. This CPU cooler stands 178mm tall, with a footprint of 135mm x 119mm. Weighing in at 951 grams, this is one big heatsink that will only fit in full size tower chassis. The Shagon AHC-118 heatsink is built around six 6mm diameter copper heatpipes and a 120x130mm aluminum fin stack. The heatsink features an exposed heatpipe base and utilizes a single 1800-1000RPM 120mm PWM fan.
