I recently purchsaed an SR7012 as well, but haven't hooked it up yet, partly out of concern about the heat that this unit generates (which is also a common complaint about similar Denon models). From what I've seen, for those who are concerned about the heat and have a closed cabinet, the AC Infinity Aircom T8
seems to be the "go to" fan to cool off hot receivers. All of the marketing materials for this fan even show it on top of a Marantz receiver - so clearly this is a common issue with these units. The general feedback is that the fans are sturdily built, match well aesthetically, and work great to cool off the receivers - but I've also seen where they can be louder than some would like (depends on how far away you're sitting, whether the cabinet is closed, what you are listening to, how hot your receiver is running, etc.). You just need to make sure you choose a model that vents air the way that works best in your cabinet (rear, front, or overhead exhaust). The other downside is that these units range from $80 to $120 depending on what model you choose - but probably a good investment to keep your gear from overheating.
There seem to be a variety of other things to try to keep the receiver cool - using Eco mode (which limits your power), using external amps to take some load off, etc. If you do some searching around here or on Google you'll find a lot of hits about this - I'm just regurgitating what I've already read, since I haven't fired mine up yet to see how hot it runs.
Otherwise, how are you liking the SR7012?
