Axiom Home Page Forums General Discussion Advice from Axiom Owners Coolng AVR

Just wondering. Does any other Onkyo owners use some type of fan to help cool it down some? Mine (707) is in a stand that is of an open design but the Onkyo still runs a lot hotter than the Rotel ever did or does. I took a temp reading and the ir therm was reading 128°F. The Rotel was around 30° cooler.

It's powering the VP150 and 2 QS4s. The Rotel is handling the M80s. I couldn't imagine how hot the thing would be if not for the Rotel.

Onkyo's are known to run hotter than most other brands out there.

no kidding Rick, I wonder if you could get the Onkyo to shut down with your 80's if not using the Rotels? I've heard they run very hot.

I have a 707 and never noticed it running hot. It has never shut down. I ran snell type e-3 mains until a few months ago. Now I am pushing the w22 in walls with surrounds all the time.
It runs warm to med warm, but never hot.
Of course I run the surrounds and centres as small. Maybe that has something to do with it?
The Snells were always very easy to drive.

my onkyo txsr700 has been driving my axiom 80`s for 6yrs+ now, no trouble. it does get very hot ( fry an egg hot) no fan added but in an open audio rack...my room is 20` by 30` and have had it @ over 90% on many occasions....on good recordings distortion is very audible @93-95%(have not gone beyond),but i still crank it up for a song or two @ these levels once in awhile..my reference level is 65-75% but has been on for 4-6hrs straight in mid 80`s on several occasions,also no trouble...
on that note still have decided on my new avr yet looking @ denon 3310 or 3308(refurb)

Yes. I fan cool my 906. Problem is that fan cooling makes inside the cabinet very dusty, so you have to vacuum it often. Not necessary to cool, as long as it's in an "open" space (accrdng. to mfr.). My old Haflers and Apts never got this hot on their top surfaces (and I was very mean to them), so cooling makes me feel better (and probably not much else.) The dog now hates to lay within its intake or outake paths. There's also the whhrrr factor, but that's more reason to live loud.

I still use my Snells in my shop. Had 'em since '83--reconed in mid 90's. Boy, they cost a lot of 1983 dollars.

No *&^%
I love the snells. I miss them, but my current setup requires the w22's. And the w22's do exactly what I need.

They sound nice to, but I think the snells were a little "easier"?? Maybe open??

I believe the Onkyos have historically ran hot, so does the H/Ks ... my H/K runs hotter at idle than the Rotel does after being played for a period of time.

I have a fan blowing on m equipment rack as a whole but I’ve always done that not in response to owning an Onkyo. I did do a stress test to see what my Onkyo 3007 could handle before deciding to keep it:

Since then I’ve never had any problems with it shutting down even during 16+ hour movie/gaming sessions at 80dB reference volume driving 3xM80s, 4xQS8s and 2xM22s at the same time. M80s crossed at 40Hz all others at 80Hz.

I can’t find the post right now but in one of the 2 Onkyo 3007 threads as AVS one member posted a picture of 12 computer fans arrayed 3x4 across the top of his 3007 pulling the heat up and out of the case. Seemed a bit excessive to me.

P.S. if you read my next post in that thread I did get it to shut down after about 5 minutes when I bumped it up after 2 hours at 100dB to 105dB.

P.P.S. YMMV and all the other usual disclaimers.
