Can you put your ears close to the avr to determine whether or not the internal fans are running?

The avr may be cool because its internal fans operate prematurely. Fans operating at just 44 Celsius indicate a loose contact in the same board-to-board connector that's been the source of loose contacts that have caused a myriad of other symptoms.
With a 6 to 8 ohm speakers load a 4520CI doesn't get very hot for 5.0 setup typically. You assuming because the AVR is not getting hot that the fans are kicking in, never encountered that situation.

Hi my question is about Denon 4th Link on the 4311 and Denon HD Link on newer Blu-Ray players.

I know HD Link is not backwards compatible but would it be possible to connect a RJ-45 to Coax Balun converter to get it to work..

Has anyone tried this ?


Any help appreciated.
Thanx.

I would not assume anything of that sort so I asked and if I may ask again for whoever is concerned to find out, one way or another, whether the fans are actually running.

Fact is, the internal fans should not activate until around 70 Celsius or 184 Fahrenheit (if my conversion is correct), unless there is a loose contact or short in the thermal sensing circuitry.

It's always fun to see these heat posts come up every few pages. I have all my equipment in a rack with about a 1" air gap on the top of the 4520, I have four 140mm fans in the back of the rack pulling air through; every component (including the 4520) is cool to the touch.

Are they "triggered" or how are they implemented?

My experience with them wasn't as good when I sent them my AVR-4802R--After 2 to 3 months of unresolved complaining I contacted Denon HQ in New Jersey and they rectified the situation to my satisfaction, but I wasn't happy with the journey....

Of course and as quoted above--YMMV.

I was trying to find a way to get a "triggered outlet" controlled by my receiver but I couldn't find anything economical.

I ended up buying one of those smart strips that turns on power to a strip based on control device. Cheapest here: http://mobile.walmart.com/ip/CyberPo...ector/14968093

Whenever my receiver is on the fans automatically turn on, when my receiver turns off the fans automatically turn off too. It's awesome.

I bought four 140mm computer fans and zip tied them together so I have one big square, I bought a power brick power adapter that has a computer Molex plug on the one end to connect the fans to and is plugged into the power strip.
