Noctua NF-S12B FLX
As we’ve seen with Noctua’s NF-S12B, it continues their tradition of premium fans that showcase conservative aesthetics and solid cooling performance in a silent setup. We do believe that performance is where products are made or broken, and the S12B is indeed an improvement on its predecessor.
There is always a tradeoff between performance and noise, and the Noctua NF-S12B creates an excellent balance between the two here. The NF-S12B is extremely quiet overall, there is barely a rush of air if you put your ear close, and it will be inaudible inside your case. However, the Antec fan was not only noisier but also provided less airflow. Noctua fans are renowned for their low noise levels, and the NF-S12B is no exception; this is one of the quietest fans we’ve ever come across. Your RAM fan, GPU fan, or hard drive will make more noise than this fan, so there are no worries here, especially for those craving a silent build.
With a price tag of approximately $25 USD, the Noctua NF-S12B is expensive, there’s no debating that. But you do get a premium fan in return that will last very long and run very quiet. This fan likely tends to serve a more niche market, particularly those craving a silent PC. If you are a silent PC enthusiast, we suggest an Antec P180/182, a passive GPU, a Solid State Drive, a passive FSP power supply or Seasonic fanned unit, a Noctua NH-C12P heatsink that comes with the equally silent NF-P12 fan, and then installing a couple of Noctua NF-S12B’s for intake/exhaust case fans. That, my friends, is one silent build, end of story. And notice that all the fans in that build are Noctua; there’s very good reason they continue to impress us and we continue to highly recommend them.
