CM Sphere is the latest CPU cooler from Cooler Master, using a very unique design based on a radial fan. This cooler is 100% made of copper, using four heat-pipes and according to Cooler Master it also helps to cool down the components around the CPU, such as the motherboard voltage regulator and the chipset.

As you can see on Figures 2 and 3 this cooler really looks like a sphere, hence its name.

As you can see all parts are made of copper (fins, heat-pipes and base) and as we mentioned earlier this cooler features four heat-pipes, as you can see in Figure 4.

In Figure 4 you can also see in the middle of the cooler part of its radial fan (on Figure 5 we have a better view of this fan), which glows blue when the system is turned on. This kind of fan blows air more evenly compared to axial fans, which are the kind normally used on CPU fans. By the way, the first cooler we’ve seen using a radial fan was also a model from Cooler Master, called Aero 7, back in 2003.

The base of this cooler comes protected with a plastic part, as you can see in Figure 6.

Sphere’s copper base is very smooth, as you can see in Figure 7.

The only thing we didn’t like about CM Sphere is that it doesn’t provide any speed control for its fan, so it is always running at its maximum speed (and thus producing its maximum noise level). It uses the traditional 3-pin connector, meaning that the fan speed isn’t automatically controlled according to the CPU usage, as it happens on fans using four wires.

This cooler is compatible with both AMD and Intel CPUs and it comes with all necessary retention mechanisms plus one tube of thermal grease.
