Cooler Master is a Taiwanese company specializing in PC cases, power supplies, and cooling solutions. They made their name with high end aluminum chassis years ago, and now offer a wide range of cases — entry level, mainstream, and enthusiast — that are usually sleek and stylish, rarely gawdy or overdone. CM cooling products are less well known, despite the fact they have some interesting products including liquid cooling systems and spherical heatsinks.

The Hyper line of tower heatsinks is relatively obscure, but the new Hyper Z600 is difficult to ignore. Cooler Master's name does not have the weight of Thermalright, Scythe, or Zalman, but this massive heatsink carries itself with an aura of authority that transcends brand names. Weighing in at more than one kilogram and measuring over six inches tall, the Z600 is a true heavyweight.

The Hyper Z600 arrived a bit worse for wear, but otherwise unscathed. Despite the cooler's size the box is actually more compact than most.

The Z600 is an enormous, shiny tower heatsink.

Cooler Master Hyper Z600: Key Features

Feature & Brief
Our Comment
The interlaced fins maximizes the dissipation surface to provide superior cooling performance. We've seen interlaced fins before, specifically in some Scythe products. It leads to tighter fin spacing, which may not be ideal for a passive heatsink.
Unique “X” design creates lower back pressure to make air pass through heatsink quickly and guide more air pass through the heatsink. The "X" shape also increases the span of each fin, which increases airflow resistance. Not good for passive cooling.
Mirror-coated copper base and 6 heat pipes ensure 100% contact with the processor to maximize the heat conduction. It could draw heat from CPU to the heat pipes immediately. A good base is important, but having it polished to a mirror shine is not. In our experience, it simply needs to be flat and reasonably smooth.
Optimum fin space allows air pass through heatsink quickly. Narrow fin spacing allows for more fins and greater surface area. Wide fin spacing improves performance with low airflow. We'll see if the Z600 has reached the optimum balance.
