Noctua NF-S12B FLX — designed to be quiet

Unique color score and silent operation mark out these Austrian made fans among others



  • Product quality
  • Lots of accessories
  • Very silent
  • Decent airflow


  • Low static pressure
  • Price

Noctua NF-S12B FLX has demonstrated great performance/noise ratio. Thanks to “beveled” blades with sharp attack angle NF-S12B FLX provides a decent airflow, although, static pressure is not something to boast of. Therefore, NF-S12B FLX fan is advisable to use as a case fan or for cooling heat-sinks with low fin density. NF-S12B FLX shows great overall product quality including accessories which is, by the way, typical for all Noctua offerings. Ultra durable SSO bearing delivers long fan operating life while coupled with SSD 2 motor, used in NF-S12B FLX, results in very low noise generation.

In spite of its relatively high price, EUR 19.90 / USD 24.90, we highly recommend Noctua NF-S12B FLX fan for purchase, especially to silent PC enthusiasts, thus, the fan receives our award:

Special thanks to Noctua for providing fans for testing.
