We have reviewed a large selection of Noctua products over the years, and we have become very familiar with their distinctive design for cooling fans. The color scheme used can not be confused with any other brand, and in action the performance is hard to match, too. Things changed over at Noctua recently, and with the launch of two new lines of fans, comes two new color schemes and a bunch of feature changes.

The promotional image above shows off a pair of Noctua's industrialPPC fans, wher the PPC stands for Protected Performance Cooling. These fans offer a black fan body and feature-wise among other things they offer dust/water resistance, and 3-phase motors for reduced power consumption and smoother/quieter operation. The other line up is named redux, and these grey colored fans offer a more entry level, budget friendly take on the Noctua fan that still offers all of the high end features people have come to expect from Noctua.
