    My 875 gets really hot (too hot to touch) even with a two channel amp powering my fronts. However, I have never had it go in protect mode. Mine is not enclosed and I do not use a fan. However, if it were in a cabinet I would definitely use a fan.

    Ugh....if it needs a fan, I want no parts of it.

    Well said! A well design amp will never need a fan to cool off. No matter how quiet is the fan, you will always hear some noise coming from it (unless it is unplugged lol) . People should listen to music, NOT the amp(transformers or fans)!!!;)

    Let me add to this discussion by saying that just because an AVR or amp (there is a huge difference) gets hot is no reason to worry or not purchase the piece. I get the impression that some think if the piece isn't cool or slighty warm that there is a problem. Well, there isn't. Now, if an AVR or amp goes into protection because of heat issues, then you can worry.

    Well said Jesse, I agree 100%. I have an Onkyo and have had them as long as I can remember. Yes they are space heaters, esp the back right corner, but well ventilated there is no need for a fan at all. It may help with piece of mind, but is on no way a requirement. I have pushed my 806 for hours at moderate levels playing Blu Ray's, COD on the PS3, and listening to music and while it does get pretty darn hot, I have had that thing for almost 2 years now and not a single ssue (knocks on wood) Onkyo makes some damn fine AVR's and when it comes time to upgrade, Onkyo will be on the top of my list.

    Are you using external amps, Kunta? If so, that would definitely help the Onkyo to run a lot cooler.

    Nope. Driving all 9 channels off of the 1007. Nary a blip. I ran a 7.1 setup off of a 705 before that, and though it got warm, it never got hot enough to cause any issues... and I never once heard its fans kick on.

    Onkyo TX-NR3010 9.2 AVR
    Emotiva XPA-3 amp
