I want to install 9 fans in the enclosure but I heard that if I put the three fans at the bottom so that they suck the air in, it will cause a wind howl. That's why I want to install all 9 fans so that they blow the air from the inside to the outside. I wanted to ask whether I can install the fans in this way without having to compromise with the airflow and if so, whether the wind whine would not be present.
