The Sphere is an all-copper, quad heatpipe and fin CPU cooler shaped like, you guessed it, a ball. It comes with a single-speed radial fan built in, instead of the typical axial fan you find on most CPU coolers. The radial output of the fan helps to cool other components in the immediate vicinity of the CPU socket. This combination of round-shaped fins and radial output fan put the sphere into a fairly unique class of cooler?
