Today we are looking at the Killer Whale Premium CPU cooler from Deepcool. With it being named after a whale you would imagine the cooler would be big and heavy. The Killer Whale Premium is not that large, but it is quite heavy: 1.225kg or 2.7lbs heavy. This is mainly due to the cooler being completely made of copper.The Killer Whale Premium is a C-shaped top-down style cooler. The fan for the Killer Whale Premium is slightly different than a standard 120mm fan. A standard 120mm fan is 25mm thick; the fan for the Killer Whale Premium is 48mm thick. The extra thickness allows for more static pressure at the same RPM as the thinner fan. The fan for the Killer Whale Premium operates with an RPM range of 800 to 1800 RPM, 19.1 to 31.8dBA, and pushes up to 78.31CFM.
