I currently have the AVR 525 and the fan is way too loud and comes on about every 15 minutes. I'm wondering if the AVR 7200 uses the same fan design as the 325/525? I only found one picture of the rear of the 7200 and I did not see a fan. But the Harmon web site makes reference to a fan in one of the FAQS. Any comments on the receiver and performance of the fan would be appreciated.
