I went ahead and made the purchase last night. It took about 1 minute to install the Antec Fan. The fans are very quiet and within a few minutes it cooled down the cabinet enclosure that houses my AVR 4308 and DVD player. I didn't take temperature measurements but I could feel the difference. Like itschris says, "it's cheap insurance". Don't know why I didn't do this years ago..... At $70 the Antec A/V Cooling System is a keeper.
