These fans are touted as being quiet with reasonable airflow. The airflow isn't stellar on just one, but at only 21 db, you can put 4 total in the 1030 case and get more than enough (on modestly O/C'd systems) airflow with minimal noise levels. The major downside on these is they don't support RPM monitoring even if you add a third wire to the exposed pin. I bought 10 when bgmicro had them for $1.99. I'm tempted to jump on this deal since the connectors will be easier to deal with, but even at $3.25 it's a bit steep when shipping is factored in for something I don't have an immediate use for.
