Ninja Athlon64

[flexy]

guys and girls, i need your help. my AM2 box cooler is showing all signs of going to hell so i need a good and silent cooler. i liked Scyte's Ninja but what i really want to know is can thah heatsink cool Athlon64 X2 3600+ without fans. that would be great. case fans are present so there is a good level of airflow. the case is Antec NSK4400, so will the Ninja fit?

too many questions, thanks very much
