Deepcool's IceEdge 400XT heatsink is a mid-size tower cooler that stands a modest 127mm high and weighs 585 grams. At its heart are four, 6mm diameter copper heatpipes and a 92x100mm stack of dark nickel plated aluminum fins. As with DeepCool's other heatsinks, the IceEdge 400XT ships with a novel rubber clad 92mm PWM fan. Every bit of the fan frame that makes contact with the heatsink is covered in a rubbery material so motor vibrations are greatly diminished. The 92mm DeepCool brand fan spins at 2200-900RPM and moves ~40CFM air according to the maker.
