Nanoxia announces itself as the only brand in the PC industry allowed to make use of a specific piece of technology, employed by German car manufacturers to circulate air in the seat heating of their cars. This enables them to offer the first virtually vibration-free PC fan in the world.

You all know the effect what happens, when you connect a vibrating fan to a solid body - noise is generated. This is one of the main sources of fan generated noise. In order to counteract this effect, the user had to employ various forms of decoupling materials. With our fans of the Special N.N.V. series, this problem is solved once and forever. The new "No Vibrations" principle provides us with torques of a particularly pleasant nature.
