FunkyKit posted a review on the Noctua Redux and industrialPPC Fan Round Up
A quote from the article:
Today I will be reviewing Noctua's "Redux" and "industrialPPC" line of fans. The most exciting and highly anticipated feature of this new line of fans are the colors. To some enthusiasts, color is a deciding factor when choosing a fan because many cases have a side window to show-off the beautiful hardware. Noctua fans are widely known for their durability and performance and not so much their aesthetics. Now with the new color options to choose from, Noctua has appealed to many of us builders out there that may have sacrificed performance for style. These fans offer the superb performance expected from Noctua and now some style points to boot. The new colors look sharp and even though they are not your coffee and cream color, Noctua has still built a highly distinguished set of fans. The build quality is noticeable from a distance and I am sure that these fans will hold true to Noctua's standard of high quality performance.Noctua Redux and industrialPPC Fan Review Round Up @ FunkyKit
