Thanks, that helped. But now the temperature ranges between 115-125F, without any extra case fans. With one 80mm fan, I can drop the temp. range into 105-110F. I tried looking for recommended temp. ranges for 2500+ but couldn't find it at amd.com, does anyone know (roughly) the max recommended temperature? And is anyone aware of any places online which sell close to inaudible 80mm fans?
