Useful fan

When I have the fan mounted first unentkoppelt on the side wall of my Towers, the noise was quite annoying, but as I soon get some new fans I have him ever mounted on the back wall, where he is now and as the vibration noise is no longer heard so probably a decoupling with the silicone pins will not change much. But to hear it is unfortunately the airflow, but this probably is also due to the perforated plate, what the fan is attached. When it is quiet, but the noise is a bit annoying.
Otherwise, the fan runs nice and quiet and I have to be faulted. For the price and the air flow rate of 96.8 m³ / h, the part is not a bad choice, will have as long as you do not have silent PC /. He could in fact already running a bit quieter I think. I consider myself times as moderately sensitive to noise a.
