Summary: This case fan pushes a lot of air and gives excellent airflow throughout the case. The fan comes with both 4-pin and 3-pin connectors. Plugging the fan into my motherboard header allowed me to change the fan's speed. Running it at a lower speed was much quieter, without sacrificing too much airflow. Quality product by Antec.
Summary: At 29dba, definately not silent, but not loud. Great for keeping your case cooler. The fan looks great and the 3pin/4pin connector is handy for installing when you might not have the right connector. Long life fan.
