In addition to our standard line-up of premium quality quiet cooling fans that feature all our latest technologies, come with a complete set of accessories and are easily recognisable by our signature brown colour scheme, we carry three extra product lines:


The redux line addresses price-conscious users by reissuing some of our most popular, award-winning models and presenting them in streamlined, more affordable packages. Redux line fans feature an attractive light/dark grey colour scheme that is reminiscent of the two shades of brown used in our standard line-up. 


The industrialPPC (Protected Performance Cooling) line is conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection. These ruggedised high-speed versions of our standard models are ready to work in challenging environments and come in an all black design.


Maximising colour choices, Noctua’s chromax edition fans can be colour-customised using the included swappable anti-vibration pads as well as optional anti-vibration mounts and cables. This makes them ideal for enthusiasts looking for true premium-grade fans that can be colour-coordinated with popular build themes such as all black, black & white or black & red.
