Summary: I've owned the Antec Nine Hundred for 5 years, and my third one of these just died. Pro: good airflow. Con: seems to die pretty quickly, obviously given past experience. Also it's not a standard square shape, meaning you can't replace with any 200mm fan.
Summary: I have gone through a few of these on my husband's PC. He has an Antec case with this at the top and it does a great job, but the plastic is so brittle it breaks fins off if anything comes in contact.
