The Coolermaster Hyper Z600 heatsink is a novel passive CPU heatsink for today's dual core processors. Its' 'star' shape, widely spaced aluminum fins and prodigious number of silvery copper heatpipes allow it to work without the benefit of a fan, albeit within specific thermal limits. The heatsink should never be used in the passive mode with a CPU having a TDP greater than 89W. The Hyper Z600 heatsink isn't sold with a fan, but it does ship with two fan brackets for attaching 120mm fans to the side of the unit.
