"The focus of this Frostytech review is the Thermaltake Contac 29, a new mid-sized tower heatsink from this well known Taiwanese-based manufacturer. The Contac 29 heatsink stands 160mm tall and ships with a fancy looking orange impeller fan that reminds me of a washing machine agitator on steroids. Three 8mm diameter copper heatpipes are exposed at the base of the heatsink, thus making direct contact with the processor's integrated heatspreader for optimal conduction of heat energy."
