DeepCool's Gamer Storm Lucifer K2 heatsink is a revised version of the original Gamer Storm Lucifer heatsink, which Frostytech tested about a year back. The Lucifer K2 heatsink only differs in that it's not nickel plated and ships with a slim profile (20mm thick)120mm fan which makes the heatsink a little more accommodating on confined motherboards.
