  • Solid performance in a passive configuration
  • Superior performance in an active configuration
  • Quality construction and design
  • AMD & Intel socket compatibility
  • Six heatpipe design allows for unexpectedly good socket area clearance


  • Dimensions may be too large for some cases
  • Weight, at 1045g without fans, is prohibitive
  • May cause access problems to DIMM slots on some board configurations
  • With an expected MSRP of under $100 USD, may be of questionable value vs. other top tower designs

Upon first seeing the Hyper Z600's specifications, we were skeptical of the claim that it would perform well in a passive configuration.  This was, in large part, due to our experiences with Cooler Master's GeminII cooler, also marketed as a passive cooler, which performed well with fans attached but was poorly suited toward a passive design.  Lets be clear of one thing: this is no GeminII.

We were pleasantly surprised to find that Cooler Master can rightfully label the Hyper Z600 as a passive cooler, performing well on even a slightly overclocked quad core processor. Adding active cooling and excellent airflow, however, are the key to turning a well-performing passive cooler into a solution that should compete with the best tower designs on the market.

Do note, however, that the Cooler Master Cosmos played a significant role in the result seen due to its superior airflow. Still, even with the rear exhaust fan disabled, the Z600 continued to perform quite well (dual top exhaust fans were still functioning).  Bottom line? This is a superb cooler for those with a chassis that offers sufficient real estate.

Thank you to Cooler Master for giving us the opportunity to review their Hyper Z600 CPU Cooler for our readers.
