Deepcool's Ice Matrix 400 heatsink is a relatively thin profile tower cooler that stands 160mm tall, but is only 71mm deep. It weighs upwards of 1030grams and is built with no fewer than four, 6mm diameter copper heatpipes. As with DeepCool's previously tested heatsinks, the Ice Matrix 400 ships with a novel kind of fan that skips the whole rubber-fan-post fad for a resilient layer of rubber in the fan frame itself.
