More is not always better. Whoever said ?you can't have too much of a good thing? has obviously never worked with computer airflow?or he has and he is very hard of hearing. Is airflow a good thing in your computer? Of course it is. Will more airflow produce better temperature performance in almost all cases? Of course it will. Does more airflow mean more noise? In almost every case, the answer to this is a resounding ?yes?.

When it comes to airflow, the optimal amount can vary greatly from situation to situation, and will be completely based on preference. Most will find that having the fans set on a curve to provide only the airflow that is required to be the most advantageous. This insures the lowest possible noise while providing the required amount of performance. In systems using multiple fans in multiple areas, the needs of each individual fan will also be different. Some motherboards may have enough headers to accomplish this, but most likely they will not and software may be lacking and temperature probes non-existent. For many, a fan controller will make a lot of sense to truly optimize cooling needs.
