I am kind of happy that the fans did not turn on, no noise, on the other hand if Onkyo feels the need for 2 big fans, when should they be on or is something wrong with my 809. My hand over the receiver feels barely warm.

If I hammer it with some bass heavy dubstep for 30+ min, they always come on and their not loud. This is with my two 120mm fans on top running quitely and the temp reading on my oRemote iPhone app shows 150 - 160F. Normally when pounding it, I turn the case fans on max, still can't hear them over the music and it keeps the temps around 115 -120.
You guys are just not working it. Movies generally won't punish it enough, too many volume variations. Try some constant bass heavy music. I do not listen at Referance level, usually between 15 - 10. I also have large speakers, my mains have 15" woofers and I do use all 7 channels as well.
This is all down in my cool basement, with it in open air, no cabinet. The 809 will get hot if pushed a bit.
As I mentioned in another post, I opened the case and put copper heat sinks on all the main chips on the HDMI board, eight of them. Hopefully keep them from failing (loosing connection to board) due to heat. And some chips got scorching hot when I was testing. Still amazed their we're not heatsinks on some of those chips.
Give it a hard run, should get those fans to kick on.
