True, when running at max speed the fractal fans are not quiet. But they are less noisy then a lot of fans at a given speed. The airflow to noise ratio is not great, though.
Admittedly, i hardly ever run fans at more then 1000rpm, and my Noiseblockers dont go any higher then that, so i couldn't do a comparison at higher rpm.
So in general, i would say the fractals are worth keeping if you run them at <1000rpm and don't need very high airflow for hot hardware.
