Cooler Master Hyper Z600 Passive Heatsink Review
Cooler Master Hyper Z600 Passive Heatsink Review
  0%   
Abstract: Cooler master's 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.

FrostyTech Mk.II Synthetic Thermal Heatsink Test Results
Intel Pentium D / Extreme Edition & Quad Core class heatsinks tested at 150W
Intel Core 2 Duo / Pentium 4 / Celeron class heatsinks tested at 85W

Results based on readings from a 30x30mm copper interface die with 150W and 85W heat loads applied on the LGA775 version of the Mk.II Test Platform. Temperature results listed for each heatsink were calculated by determining the rise over ambient temperatures at time of test. Information on Frostytech's test methodology is available here.

*Heatsinks are ranked according to the 150W thermal test results column (rise over ambient temp.). Low temperatures with low noise levels are considered best. For reference heatsinks with variable-speed fans, only the high speed (12V) fan test result is included in the comparison sheet; more detailed results reside in each specific heatsink review.

Intel processors vary in power output between single and multi-core models, so FrostyTech tests heatsinks with two thermal loads that represent the upper limit of each CPU family; 150W and 85W.

With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform, the Coolermaster Hyper Z600 heatsink maintains an excellent temperature of just 18.0°C over ambient. The 120mm Mechatronic fan keeps noise levels at an unremarkable 47.7 dBA.

The Hyper Z600 was then tested with a 85W heat load, resulting in a slight 11.6°C rise over ambient temperature. It's possible to add a second 120mm fan to the other side of the Coolermaster Hyper Z600, but for the purposes of these tests only one fan was used.

Since the Coolermaster Hyper Z600 is sold and marketed as a passive heatsink, Frostytech set forth to test it on the synthetic temperature platform without active cooling (ie. without a fan).

The Coolermaster Hyper Z600 was placed in a horizontal and vertical orientation while 150W and 85W heat loads were applied. No fan was installed on the heatsink, and no fans were located in the vicinity directing airflow towards its general area.

In other words, these were true passive cooling tests!

Coolermaster's Hyper Z600 heatsink failed both the 150W and 85W tests while it was left in a horizontal orientation (ie. as it would be when a motherboard is sitting flat on a desk).

When the Hyper Z600 cooler was rotated 90 degrees, so that its aluminum fins were oriented vertically, the cooler failed the 150W test only. With an 85W heat load, and its aluminum fins pointing straight up, the Hyper Z600 heatsink was able to maintain a rise above ambient temperature of 56.5C passively. No fans, just convective air flow here folks.

In the confines of a case, it's hard to say if the same results could be relied upon. Still, the Hyper Z600 did keep temperatures steady, if elevated dramatically, with an 85W heat load.

So there you have it, when the Coolermaster Hyper Z600 heatsink is equipped with at least one 120mm fan, it's an excellent high performance cooler. It's up to you to accept the +1kilogram weight. As a passive heatsink, the Hyper Z600 is capable so long as case ventilation is adequate and the maximum processor TDP does not exceed ~85W. The results aren't going to be record breaking though. In Frostytech's books, an actively cooled Coolermaster Hyper Z600 heatsink is well worth your consideration.
