The novel surge baffle system is integrated in the mounting and absorbs emerging vibrations between fan and holder; this means that additional decoupling is no more necessary. Due to this novel surge baffle system the fitting dimensions rest unmodified, in order to permit assembling of every commercial 120mm holder.Thus this smooth and ball bearing fan, which interacts with the integrated surge baffle system, guarantees minimal running noise.The fan brackets are installable without screws and can be turned through 180° so that it can be mounted not only to create a pushing airflow but also so to provide a pulling one.Additionally the N-120-B comes with a modern colouring and a cool coloured LED-Fan.
