  • Noise: 18.1 dBA
  • LEDs: None
  • Connector: 3-pin
  • Dimensions: 4.7 x 4.7 x 1 Inches

Noctua remains to retain the authority of the case fan territory, and it’s made something a bit new with the NF-S12B redux-1200. This new model doesn’t highlight the classic brown-and-tan color blend that, though a trademark of Noctua, all but guaranteed the fans would never suit the aesthetics of nearly any PC build. Instead, Noctua has remained for a simple, two-tone gray that can combine in a lot nicer.

Apart from the tone switch, you’ll still get an extremely competent fan that can boost air up to 59.2 cubic feet every minute while keeping a low noise level at 18.1 dBA. You can support the fans to stay quiet with the rest of your pc using free anti-vibration support, which appears in a mixture of colors if you want to change the gray slightly. There’s also a choice to run these coolers at slow rates to lower the noise levels even further using Noctua’s NA-SRC10 Low-Noise adaptor or by lowering the voltage.
