EVGA have recently changed the way that their HydroCopper branding works. In the past HydroCopper refereed to models which included a factory-overclocked reference PCB and a factory-fitted, full-cover water blocks, allowing users to add this to their liquid-cooling loop as they saw fit. However EVGA's new direction for HydroCopper is to include its own closed-loop cooling system, seeing a similar design to AMD's reference Radeon R9 295X2.
This included cooler features a metal base-plate, drawing heat from the memory and VRM, connected to the central pump-block and an aluminum fin stack. Cooling these two parts is a common lateral-flow blower and all of this is ventilated by a single 120mm fan.
