I can say, without any doubt, that the Denon 3808 and the Onkyo 3010 run at the same basic temperature - neither is hotter than the other. Both produce heat, both require airspace around them, and neither one requires extra cooling to keep it running properly.
So tell us, how much hotter is the Onkyo than the host of other receivers you mention? Yes, we all know ICE amps are going to run cooler, so you should ignore those - very different technology.
Also, a look around the web at other owners of AVRs shows you most likely have a defective unit. Here is one with actual temperature readings:

3010 Temperature Measurements
Top of Unit
Laser thermometer: 105F
Digital thermometer: 105F
Compared to my Denon 2807
Laser thermometer: 105F
Both units have good ventilation (open front/rear at least 3" space above).
Sound quality continues to impress. Web-based remote control has been very useful in practice.

Others in this thread have reported the top of the unit being cool and, after running at a very high power usage for an hour straight, the internal temp managed to finally reach 123F. If your unit is runs hot, you have a bad unit and should return it, since others are not having the same issue you are having.
Yes, why have you not sent your unit in for repair or replacement since it is obviously running far hotter than everyone else's units?
Not really...its a comparative word in this scenario
If something thing varies greatly in temperature if can EASILY be determined by a touch of the hand and described as hotter( or cooler)
as for Onkyos running hot...you should take some time and read some here on AVS about the last 5 generations of their THX ultra units....which I have owned about all of at one time or another... and see what feedback owners have stated
You might be enlightened
Of the units I listed earlier ....the Onkyos have all been noticeably hotter to the touch...including the Sherbourn amp that has far more power with a real 200x5( all channels driven) than any AVR Onkyo has ever made
You mentioned something about pieces of this capability not running hotter......really?....
Have you ever used( had any experience) with a Sunfire amp...I am not sure why you relate capability to temperature.....
The fact that "heat" has been mentioned several times in this thread would indicate that owner's questioned the heat being out off from their units
Something I have not seen in other forums that I read consistently of other products I have owned( excluding the Pioneer SC units)...Yamaha Z7, A3000, Denon 4310..etc..etc
As for me sending it back...I am not sure there is a spec listed for operating temperature?....Please advise
In the past Onkyo has had information in the manual that stated the units run hot
Onkyo has replaced two of my units with a newer model...for failures
Some say they are heat related failures?..I have no idea. Perhaps the reason a lot owners use fans on their units. I never have.
I have a new 5009( in a box in my basement) for a failed 905 they replaced( for a failed HDMI board and then a DSP issue)
The other 5009 I use occasionally...does run warm..I watched The Bourne Legacy on it last night. I would say its runs about as warm as the older 875 does to the touch after 2 hours of use
As I said before..I dont own a 5010
Unless they have made MARKED improvements over the 5009( and really the last 4 generations)....perhaps you can advise on the 5009 vs 5010 on heat output from your own use and advise?
The 5009 runs hotter in my environment( using the same speakers and media) than anything I have owned...excluding other Onkyo receivers
On another note...as I read through the 3008/5008 owners forums they are starting to have HDMI issues....some say these are heat related. Again I have no idea
I will say that this same cycle repeats its self after the units have been in operation for 2-3 years..consistently over the last 5 generations of Onkyo AVRs
I have been lucky in that warranty has served me well and given me three new units of a newer model than my failed one ( 2 direct from Onkyo and one through a MHT extended warranty replacement)
also of note is there are several Onkyo failure tracking threads in this forum...such as this one
heat is mentioned more than once an issue in that thread
