The Onkyos run quite hot as it is. The 4 inches around the sides and back is fine, but seeing as heat rises, the 30mm may be a bit of a problem. It'll certainly warm the glass up some :)

It depends how you use your gear IMO.
If you like to go loud all the time it could be a definite problem, but if you're pretty average and only give it big licks occasionally, I'd guess you'll be ok, no worries.

It'll have to be a case of suck it and see, I guess.
I'm not exactly sure how hot they run in free air (hopefully someone will butt in) but as much as 40C is considered no problem. More than that and I'd be a bit concerned myself.

FWIW, I have a half inch gap above my amp :eek: but it's ok because I'm lucky enough to have fans that cut in if it gets too hot.

Here's Onkys advice for the 606;

Leave 20 cm (8") of free space at the top and sides
and 10 cm (4") at the rear. The rear edge of the shelf
or board above the apparatus shall be set 10 cm (4")
away from the rear panel or wall, creating a flue-like
gap for warm air to escape.


8 " :eek:

I think it could be a serious problem, in your case, in all honesty :(

I'd be looking to place an 8" fan behind the amp, as a minimum.

I was going to say get in touch with Onkyo, but I know what they'll say, ie no chance.

Hi there, I'm running my 606 with around 2" on either side, 15cm at the back and 10cm on top. Listening to stereo at 50 volume it is warm to the touch at the back but totally fine, however I've noticed that using a multi channel input increases the heat significantly. I would think you should be fine though as glass is a pretty good conductor and should hopefully be quite thin.

4" on top, is a big difference to the OPs setup and that's where the clearance is needed the most, IMO.
Seeing as we're talking about convection here, getting the warm out is equally important as getting cool air in.

I really think you would need to force the air, hence the fan suggestion. It's no big deal really to do it and it can be a lash of sorts, as long as it's safe, because no-one would see it.

Then again, who can get 8" space in an average setup :confused:

My 606 is inside an enclosed unit with a old xbox 360 and a sky+ box and without cooling it would get red hot.

Purchased the following from ebuyer

3 x Hiper 120mm Case Fan http://www.ebuyer.com/product/105137
1 x Hiyatek Black Multi Fan Controller http://www.ebuyer.com/product/136404

Put the fan controller in to a 5 1/4 external dvd enclosure (which also provides power for the fans).

I have 2 fans at the top and 1 at the bottom, top 2 sucking air out and bottom 1 blowing air in.

Even with the 360 on and the door closed the temp is fine.

Will post some pics tomorrow show you how much space is around the amp etc.

Dang!!!! I'm gonna have to install some fans, I have about an inch to spare as my set up is, 606 Tosh EP35 HDDVD, V+ Box and Tosh DVD Player and I thought it was getting hot.

Does anyone have any tips or links for cooling equipment.

I already have 3 120mm fans lying around somewhere, just need advise how to house them and power them?

The key is to get the air moving...it does not have to be that fast...the larger the fans the better as you can run them at low RPM reducing the noise.

I have linked a pic of the controller mounted in a 5 1/4 external bay which provides power for the fans as well (though I had to buy some 60cm fan extension cables)

Think I may have 2 kill the blue leds tho ;)

(sorry for the shocking pic quality...my mobile was all I had to hand at the time)

Cheers for that.

Where did you procure such wonderful equipment to design this. Have you mounted the fans on the back of your AV rack/stand I can't quite tell from the pictures.

The only concern stopping me from buying this amp. Any ideas why it runs so hot compared to "other" amps?

If it produces more heat than equivalent amps, at the same output, it would mean that the indvidual amps are less efficient, simple as.
Power goes two ways; The first part is into the speakers and the rest is dissipated with heat.
I think the main transformer is up to the job, but the independent amps, aren't. This has to some extent been proved, in that the 605 has been slated for ultimate power in surround.

Perhaps the Onkyo people could address this issue?

Having said all that, you are getting a lot for your money :)

Duh, I'm being a bit obtuse, in that I don't know what class the Onky amps run,
I'm guessing C, as opposed to AB, but who cares?

Some classes are better than others and will cause more heat, but sound a lot better.

Don't we all mate :D

The thing is, if Onkyo are playing the game I think they are, you will get more heat, simple as, but the sound will automatically be better. I need to look into this more myself, tbh.
That aside, what else are you comparing the Onky too? and what are you looking for/expecting to be better?

805's, 875's and 905's run very hot too. people blame it on the Darlington "dual push-pull" amp design (28 devices alltogehter, 4 per channel), the 605/606 however, doesnt have this., so i really dont know the answer to this one.

HDMI 1.3a 3+/Dolby True HD/DTS Master HD decoding. The 606 is the only amp to do this for <£400 ASFAIK.

My current amp only cost £150 so I do think it costs too much - all it does over my current amp is add support for decoding some new standards and a HDMI switcher - which is how I see it.

I do think we are getting seriously ripped off. But compared to other amps this is half the price of a comparable Denon amp. :) So in that way, it's cheap.

605 does it for £100 cheaper
