Cooler Master's engineers have taken the idea of releasing a fanless cooler seriously and have come up with a passive CPU cooler called Hyper Z600 that can cool both Intel and AMD CPUs drawing up to 89W without any fans attached to it. You can add two optional 120mm fans to the opposing sides of the heat-sink in a push-pull configuration, though. The Hyper Z600 measures 127.28 x 127.28 x 160 mm and weighs exactly 1045g. The heatsink structure features interlaced aluminium fins, six heatpipes connected to a mirror-coated copper base and Cooler Master's unique "X" design that creates lower back pressure to make air pass through the heatsink faster. Compatible with all existing Intel and AMD CPU sockets, the passive Cooler Master Z600 will be available soon for around £34.99.
