"This leads us to the next big advantage of aluminum for water cooling...the passive radiator. Meet the Konvekt-O-Matic MAXI, can you believe this is Innovatek's mid-size passive radiator? In addition to the standard Konvekt-O-Matic, there is also a HUGE Ultra version. The MAXI measures 45x33x5cm (h x l x w) and weighs in at a whopping 10.5 pounds. And like all of Innovatek's aluminum gear, it is anodized, this one in a vibrant red color. According to Innovatek's testing the MAXI radiates more heat than an active dual 120 mm radiator." - pimprig.com
