A key factor in the ASSASSIN VC ELITE WH's extremely silent operation is the use of three-phase, six-slot, four-pole fan motors with low voltage and power consumption. The high-end true FDB bearings in each of the fans are the gold standard, and for good reason. DeepCool is so confident in our new design that the ASSASSIN VC ELITE WH comes with 6 years of limited warranty coverage!
