Cooler Master CM Sphere

The Cooler Master CM Sphere is not a brand new product on the retail market, especially since it launched in Q3 2007; but we haven't had the opportunity to test it until now. Like many of Cooler Masters products, function is usually only as important as fashion. The CM Sphere comes in a full-copper and black version, and both feature an 66mm blower fan on the inside. Cooler Master rates the fan at 84.7, CFM, but after testing this product I have no idea how they arrived at this number.

The CM Sphere operates at a very low sound level, thanks to the unique blower fan that constantly paddles air away from the fins from the inside core. It would only be fair to let the performance results speak for themselves, but the CM Sphere is not a product I expect hardcore overclocker to have an interest in because it lacks interchangeable fan functionality.


Nevertheless, the CM Sphere was a near-silent cooling solution with a good overall performance. The full copper construction means that this isn't going to be a value-priced item, but it certainly makes up for high-end performance with great looks. For your average enthusiast, or even the casual user who is building their own system, Cooler Master's CM Sphere would add some color to the inside of any computer.

Like most of the Cooler Master product line, the CM Sphere uses a proprietary securing system. The mounting system uses four screws that fasten from the backside of the motherboard, a task that ultimately means the main board must be removed for installation.

A critical component of Cooler Master's ability to successfully pursue its mission is an unstinting commitment to quality, as demonstrated by the ISO 9001 certification granted to its main manufacturing plant in Taiwan. It has also enforced ISO guidelines and is in the process of applying for ISO 9002 certification at its second and third plants, located in China. Cooler Master has also implemented a number of analytical and testing protocols to ensure top quality, including at subcontractors, to further ensure thorough quality control. Moreover, Cooler Master's dedication to quality extends beyond manufacturing to every aspect of its operation, including service.

As a company, Cooler Master is an organization that is finely tuned to the demands of providing innovative solutions that meet customer needs as rapidly as possible. Rather than adopt a traditional corporate structure and then try to retrofit operations to suit such a preexisting structure, Cooler Master's is a company built around the nature of its operations, providing maximum efficiency and strict workflow control. Focused on meeting customer requirements flexibly and efficiently, Cooler Master's workflows commence with careful surveys to understand these requirements, and then proceed to R&D, manufacturing, marketing, and sales, as part of a comprehensive and tightly integrated workflow.

Throughout the design process, Cooler Master maintains robust communications channels with customers, taking advantage of online systems as well, to keep customers informed about the status of projects and allowing Cooler Master engineers to understand customer concerns as they evolve. Moreover, Cooler Master engineers make extensive use of Computational Fluid Dynamics (CFD) analysis software tools to model heat absorption and dissipation characteristics of in-progress designs to ensure that final products completely satisfy customer specifications.
