Have the radiator extensively tested on my heavily overclocked Core i7-920. The temperature values are really good, although I have exchanged one already is mighty potent 120mm tower cooler. In 4,00GHz and 1.4V VCore I under full load at 600rpm almost 84 ° C. He should so easily cool any CPU softly. The support of Rascom is a dream. Got any problems and free the conversion kit for my motherboard sent in a few days. The processing of the radiator adjoins crafts. The installation went smoothly. If you do not have a window in the motherboard tray does have to expand the board. The only break point of the radiator is the price. To 20 euro less you get an equally strong silver twin tower cooler of the renowned competition, by half a also completely sufficient tower cooler halt blows 800rpm and is barely audible at VLT. 5 ° more power. To 20 Euro more then one gets a more potent Kompaktwakü. In short, the cooler beats in a relatively narrow niche, I'd call it a luxury product.
