360° View - Cooler Master Hyper Z600 Black Label Heatsink Information on Frostytech's test methodology is available here.
The Cooler Master Hyper Z600 Black Label heatsink ships with one 120mm PWM fan that spins at 800-2200RPM. The heatsink can accommodate up to two 120mm fans on opposite sides of the tower. Dark nickel plated aluminum fins measure 0.5mm thick and are spaced 2.0mm to 4.5mm apart. Six 6mm diameter copper heatpipes thread their way through the 110mm tall tower. The copper base is a good 3.5mm thick.
The Hyper Z600 Black Label heatsink is shown here with one fan attached. Each pair of fan brackets clip onto the side of the heatsink without the need for tools, although the brackets are attached to the 120mm fan with screws provided. The bulky body of the heatsink is elevated 40mm above the CPU for moderate clearance of nearby motherboard components.
The base of the Hyper Z600 Black Label heatsink is fabricated from a block of dark nickel-plated copper to which all six copper heatpipes are soldered. Screw holes along the outer edge are for the various mounting brackets. The base has a heavily plated machined surface finish that is very smooth and flat, it measures 37.5x37.5mm. The top of the heatsink is capped with a stamped aluminum shroud, note the 24mm plenum created behind the 120mm fan.
