Most users are irritated with noise that their computer makes. Therefore, we can find on the market numerous “silent” solutions that will solve that particular problem. Yet, there is always “BUT”. With summer heats on the way it is just impossible to cool your processor with passive cooler. But, Cooler Master has a solution even to this problem.

We got in our test lab very bulky CPU cooler made by manufacturer mentioned above. This is newest model Hyper Z600 that’s characterized by big weight: 1.045kg. Package is very nice and completely different from packages of earlier models. Bundle contains all needed screws, thermal compound and other add-ons. Quality of the thermal paste isn’t the best one that can be found, so we recommend you to use some better solution to gain optimal performances. Cooler can be mounted on AMD and Intel CPU sockets. Supported AMD sockets are 940, AM2 and AM2+, while supported Intel socket is widespread LGA775 socket. Cooling body is made from aluminum and copper. Implemented heat pipe system is consisted of 6 pipes. They are completely made from copper and have 6mm in diameter. They permeate ribs made from aluminum. Ribs are divided in two layers: external ribs that have same dimensions as cooler does (through them pass two heat pipes) and internal layer of ribs which are a little bit smaller than cooler (through them pass the rest of four heat pipes).

Base is made from copper and it is very well flattened and polished in manufacturing process, “mirror effect” is achieved, which boost heat transfers from processor to Z600. High fabrication quality can be noticed by observing of very nice and tidy joints between ribs and heat pipes. If you by any chance decide to replace silence with great performances, in package you can find plastic brackets that can help you mount on cooler two additional 120mm fans. Because of its size, we were afraid that we couldn’t mount Z600 on our test motherboard that already has bulky cooling solution for chipset and CPU PSU. But despite that, cooler sat just fine on motherboard. For mounting Z600, you must take out motherboard from case, so you can mount back-plate with screws. We commend usage of back-plate, because it helps in proper positioning of cooler on CPU and prevents bending of motherboard (because of cooler’s big weight). You should pay attention if your case is wider than 17cm if you want to avoid any contact with case sides.

For proper measurement of performances of this marvelous cooler, we provided two Intel processors, dual and quad core models and prepared them for completely different scenarios. For dual core CPU we chose E8400 with 65W of thermal dissipation, made in 45nm process and that works at default clock 3GHz, while choice for quad core CPU was Q6600 (g0 stepping) made in 65nm process with 95W thermal dissipation that works at 2.4GHz. We tested Hyper Z600 with and without fan. Temperature of room where tests were conducted was 25°C. CPUs were “tortured” with Prime95 application up to warming up limit. Temperatures were measured with Core Temp application in Idle and Full Load mode. All test results you can be seen in table.
