An incredible amount of innovation went into designing a fan system capable of cooling such a high-performance device. Instead of adding extra fans, we engineered a single, larger fan that pulls air upward through a bottom vent. As air passes vertically through the center of the device, it absorbs heat and carries it out the top. It’s simple and elegant — and also astonishingly quiet. To achieve that, we had to consider every detail: the number of blades, the size of the blades, the spacing of the blades, and even the shape of the blades. By minimizing air resistance throughout the system, we were able to design a fan with backward-curved impeller blades that runs at fewer revolutions per minute, draws air more efficiently as it spins, and creates considerably less noise.
