m0arpheus24.7dB-A is the maximum noise on maximum RPM. Since they are static pressure fans, you will most likely hear them, even when they're running on 50% and up. I had Silent Wings 3 and swapped them out for those fans and they were DEFINITELY quieter.
suparnemoYes, definitely. Silent Wings 3 are airflow fans, while the Riing fans are static pressure fans. Which means that the Riings are pushing the air with more pressure, so it can "squeeze" through radiators or other tight spaces. The Silent Wings 3 don't do that. Honestly, the Riings look pretty, but there are better CASE fans out there. They might not look as good, though. For radiators, the Riing fans are awesome :)
