Today I've got part two of the Limited Edition Cooler Master Black Label Set, the HyperZ600 CPU Cooler. It's essentially the same as the original Z600, but just black colored. It's a large and heavy cooler featuring six heatpipes and the ability to use two fans for maximum cooling performance or use no fans for a truly silent system.
