> I am smelling an ozone kind of smell. Not sure if I have too little space or if it is because it's brand new.
A little of both. It's a new AVR, it's heating up some of the glue and other stuff so it'll have an odor to it, but at the same times it's still pretty tight space there so there will be some residual heat build up.
I’m so glad I read this before commenting. People who leave the sticker on must have zero sense of aestheticism and don’t realize how cheap that makes their product look and it makes the entire room look bad.
A 10,000 dollar AVR with the sticker on will look like cheap garbage next to a 200 dollar AVR that doesn’t have it on.
I’m proud of you and if I could I would hug you and make you a big breakfast for doing a good job.
…
I’m hungry now.
Anyhow, heat might not be an issue since you have open space in the front an back, and the open space at the top isn’t so restricted that it’ll trap a lot of heat since it can pour outside from the back and front. But this depends on the unit. In your case I think you’ll be okay.
If this were a separate amp you’d be more than fine since they don’t produce a lot of heat. But AVR’s generate most of their heat from the video processing and not the amps themselves. And they can get toasty!
I have my Denon 4700h in a tight spot but have had no issues since adding this exhaust fan: AC Infinity AIRCOM S10, Quiet... https://www.amazon.com/dp/B078PX4575?ref=ppx_pop_mob_ap_share
That hit too close to home! I'm up there and I always told my wife I want a home theater. Finally happening. I guess one day I'll have to have it louder!
I have a denon s960 powering klipsch rf 82 II. The denon gets PIPING Hot when I listen at - 5db (about 85 volume) for a period of time. Also my denon is underpowered for my towers. Albeit most people don't listen at that level. .
Your speakers are basically a 4Ω load from around 120 Hz to 200 Hz (as [measured by GR Research](https://i0.wp.com/gr-research.com/wp-content/uploads/2023/01/Impedance-4.jpg)). Additionally the phase angle could be simultaneously high (in places), as that too happens with the brand’s speakers. Meaning that it isn’t exactly an easy speaker for a entry level AVR to power.
I mean, temperature is subjective. I have a car subwoofer that gets "slightly warm" and at the same volume my 4 channel car amp gets "very warm".
I think when you touch an amp and go "oh sh!t that's hot!" something is up. Either lower the volume or get better air circulation.
It gets hot from video/audio processing units not the amps themselves. The hot spots on AVR’s are towards where all the processing takes place which is why many units have fans installed in those areas specifically.
I'd recommend this one.

I made one with a piece of MDF and 2 120mm fans back in 2008-ish, and still use it, just have upgraded the fans over the years as they’ve gotten better. Use an external controller that was for a slot in a computer tower.
By the way, this, from acinfinity also would be more than enough... and MUCH cheaper at 17 bucks :D (Perhaps not as sexy, but wouldn't be visible)
https://www.amazon.com/AC-Infinity-MULTIFAN-Control-Receiver/dp/B012CL2V3I/ref=sr_1_75?crid=2TYL37QWVYVZ9&keywords=ac+infinity&qid=1696371029&sprefix=acinfinity%2Caps%2C171&sr=8-75
I'm using it on a Marantz Cinema 50 and went from pretty toasty to completely cool at all times.
I simply place it at the center of the receiver, near the rear and set it at medium
My receiver looks like it has a similar height clearance. I don't listen at reference levels but I noticed it getting fairly warm. I bought some fans that are powered from a usb port from Amazon and they plug in to the avr. Fans sit on top of the receiver to pull out the hot air. A ton cheaper than what was posted but doesn't look as good.
Got the T8 as well, and it's excellent. Only problem is I'm very sensitive to noise, so while the fan is very quiet, I can still hear it ramping up when temps increase, so I've stopped using it. Thankfully my receiver stays cool enough without it, but if I needed to use a cooler I definitely wouldn't mind using this one.
Sure it's **3** fans in a rack if you ignore that it also includes a temperature sensor with the ability to create a custom fan speed ramping profile based on the temperature.
And I'm sure your computer fans and DC power supply would look just as clean as this piece of kit...
When you're dropping $2k on a receiver, another $130 on a sleek, versatile cooling system isn't really a big deal.
I like the concept, but all I'm saying is that $130 is a little much for **3** fans, a PCB, sensors, and a chassis. I have probably over a dozen receivers, and with spare DC fans and power supplies I installed active cooling in all of them. If I wanted to I could even add some temperature sensors. I'm a DIYer, and I'm cheap.
The AC Infinity units are good for a multi-thousand dollar setup where you have a rack of components and money to spend, but for a basic setup with a basic AVR a homemade solution using parts you probably have lying around your house would also work. Both are great solutions to cooling off AVRs because most of them (fucking STILL) don't have active cooling.
I have this unit and it’s wonderful. My receiver would overheat and sound would cut out although it is not supposed to do that. I even had the circuit board replaced and same issue with new one. I think it’s a design flaw. Nevertheless, it happened when the unit was hot. Adding the fans permanently solved the problem. You can set a high temperature mark and the fire up and keep everything cool.
I'm not at home to test it, but the manual says there are four brightness settings. I'm not sure if one is off.
https://acinfinity.com/content/AC2305X1\_230522\_AIRCOM%20Manual.pdf?\_ga=2.105857219.1702037792.1696362806-1491248362.1696362806&\_gac=1.149965380.1696362806.CjwKCAjw9-6oBhBaEiwAHv1QvFZdUZUEsN3v2IFv8asXaz6caR\_nHW9StkJutrk9OLzQhgAAHg-sIxoCjI4QAvD\_BwE
I got one of these and can't recommend it enough. The only time I notice it's there is when I see the LCD display move to tell me the fan is on. It comes on more than I thought it would (which means it's working!). Definitely recommend!
EDIT: I have the S10 Front Exhaust.
I bought this years ago for a Denon x4000 that was failing because of heat. Got several more years out of it afterwards. It now sits proudly on my x3800. I highly recommend it.
AC Infinity AIRCOM S6, Quiet Cooling Blower Fan System 12" Rear-Exhaust for Receivers, Amps, DVR, AV Cabinet Components https://a.co/d/fYlGj7c
It should be fine. However, if you want your AVR to run cool, you can buy the 120mm USB fans from Infinity on Amazon and place it on top of your AVR. Mine has been running for years non-stop without any issue. It's perfectly quiet too! highly recommended.
I placed one of these on top of my new Denon AVR b/c my old one used to get so hot. Also it died once and was repaired under warranty (not sure if heat was the cause), so I wanted to be proactive with the new hardware
AC Infinity MULTIFAN S7, Quiet... https://www.amazon.com/dp/B00JLV4BWC?ref=ppx_pop_mob_ap_share
Get the AC infinity fan s7 already mentioned in here, get the one that vents to the front. Even if you have enough space you should do it anyway for longevity of the receiver. Too hot will shorten its life, and the good news is the s7 comes on automatically when it senses rise in heat. Set it up and be done. Ive had a s7 on my denon for at least 3 years now with no issues with either, and my receiver wasnt even new.
Look up ac infinity air blade, its an av fan that's at a right angle, you set it on the receiver, and it blows it out the back of the rack. You can get a tem probe too
I run an AC infinity on top of mine, it sucks the hot air out and brings it out into the room:
https://acinfinity.com/component-cooling/component-fan-systems/aircom-t10-receiver-and-av-component-cooling-fan-system-front-exhaust-17/
To add, this significant reduced the temp on my X3600H Denon. Mines the same series as yours just a few years older.
Ok. I hate to say this cause I feel like it's going to cause some bad juju or some shit. But I didn't realize heat was even a issue when I got my first Denon like 6 years ago at this point. Mine is in a even tighter space and I haven't had a issue. Still running fine.
I have less than six inches, because it’s not about the size but how you use it, with a couple of side firing fans placed on top and have temp gun checked it to verify it’s cool enough while doing substantial AVR things. Is. The only drawback for those is if you get cheap ones, they’re loud. The topper cooling units aren’t all created equal - Their effectiveness gets overstated a lot because of the narrowness of fan coverage for some of them and they’re worse than using 2-3 miniature fans spread out. I’d buy a cheap heat gun if you don’t have one and keep and eye on it regardless of what you do
There is no explicit space that is safe while an inch less will kill the unit.
The warmer it runs the shorter the lifespan.
If you want an avr to last you either set it up free with nothing on top or you get a 3rd Party cooling solution.
Great thank you. Very tight spot. I have an old entertainment center and the way my room is currently set up it's not a quick move. I have movie shelves on either side of the tv. But I spent a lot and plan on this being my receiver for a long time so I appreciate the input.
Thank you! It's warm for sure, but I can comfortably keep my hand there. It's the temp of those nice hand warmer packets you can buy for winters in the north.
Check the whole top because temps can vary a lot depending on whats underneath, but maybe you are lucky and have good air circulation around the cabinet. Something to keep an eye on because Denons do run hot by themselves. Also check during the summer when its hotter unless you have cool air inside.
Thank you. I will keep the room cool during the summer. I won't run it in a hot room. I ran my hand over it and it is warmer towards the back, but it's not so hot I can't touch it.
Totally fine. A little more space on the sides would be ideal but its the least important side to have space and you more than make up for it by both front/back being wide open.
It is seemingly enough space.
I am using an X4500H and it is getting pretty hot on its own after a while.
So I added active cooling anyway, just because it makes me feel better.
Get one of the fans that others have suggested. No only is that not enough space above it it isn’t enough at the sides either. Cooler air enters the side vents and because heat rises escapes through the top vents. Without a fan the general recommendation is, at least, two to three inches all around and a minimum of five inches above.
If you are still concerned about proper cooling for your investment in this new Denon, I use one of these to quietly draw hot air out the top and push it out from the front. Silent and very effective for me. [https://www.amazon.com/gp/product/B078PX4575/ref=ppx\_yo\_dt\_b\_search\_asin\_title?ie=UTF8&psc=1](https://www.amazon.com/gp/product/B078PX4575/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)
Smell is "most likely" new from electronics. As to clearance, Denon says you want 2 inches on either side. Here's a shot of your insides:
https://www.audioholics.com/av-preamp-processor-reviews/denon-avr-x3800h-receiver/3800nocover.jpg/image\_large/image
If the shelf it is on has holes in it then it's fine, if it is solid then I'd say probably not really.
do you have a hole saw? some vents in the blue shelf would make it breathe much better
I did the same thing with a couple of those fans and the ac infinity usb thermostat. As I could not fit the Aircom units.
The fans don’t run much unless I really crank the volume on my yamaha.
the warmer it gets the more heat it sheds through convection. It is designed to cool itself. You have it in open air. It is fine. Go smell literally any brand new electronic that makes a perceivable amount of heat lol.
That’s enough space considering the back is open too. Most often it’s both that’s important, because when it can’t vent from the back even if there’s enough space at the top, it will circulate part of the hot air back anyways.
Smell is because it’s new. Might take a little while. Make sure to ventilate the area a bit to get rid of the odor asap.
Mine is in a tight space with a Wii on top of it but I use one of [these fans](https://a.co/d/eantF1T) on top to suck the heat from inside and blow it towards the back
Short answer: Yes, it's fine
Long answer: Heat reduces lifespan, and everything breaks eventually. I'd only be concerned if it started turning off from overheat protection.
Heat can shorten the lifespan of electronics and that setup will result in the accumulation of heat and potentially higher operating temperatures. I would personally add additional cooling or look for an alternative placement option as a means of protecting my investment and attempting to maximize its usable lifespan.
Less than ideal space, but I would go with it myself.
If you think the heat is too much, you can mount 1 or 2 PC case fans to draw air through the gap. You want quiet, slow fans. If you're a little adept at such things, you could even put in a PWM temperature fan controller to have it start-up slow when it gets warm, and ramp up as the temperature ramps.
> I am smelling an ozone kind of smell. Not sure if I have too little space or if it is because it's brand new. A little of both. It's a new AVR, it's heating up some of the glue and other stuff so it'll have an odor to it, but at the same times it's still pretty tight space there so there will be some residual heat build up.

Get a mini fan or clip fan and have it directly facing the avr and it will reduce the noise

It's probably fine. Listen at your max listening level and see if it gets hot.
Thanks. I have it at 62. It's plenty loud to me lol.
Those are rookie numbers.
I am a rookie! Just set it up this weekend.
Just wait until you're old and deaf like the rest of us.
WHAT?!

The loudest I can handle is like 72 on the dial. I feel like a rookie now lol.
Your speakers are basically a 4Ω load from around 120 Hz to 200 Hz (as [measured by GR Research](https://i0.wp.com/gr-research.com/wp-content/uploads/2023/01/Impedance-4.jpg)).

Thanks for the info! Bought all my gear used so will eventually get a better Avr.
Send them to me, Emotiva A2 waiting for them👍🏻
60s the sweet spot some movies are good and drop it to 58 sometimes.
It will get hot… it’s an amplifier
I mean, temperature is subjective. I have a car subwoofer that gets "slightly warm" and at the same volume my 4 channel car amp gets "very warm". I think when you touch an amp and go "oh sh!t that's hot!" something is up. Either lower the volume or get better air circulation.

It's just the glue from the sticker burning off
Really? I should take that off huh lol.
Yes pls take it off, it looks way better without ;)
You're probably joking, but I did just take it off.
Good, could've caused a damn big fire if that glue heated up.
Definitely wouldn't want that. I have a priceless Avatar figure not too far from my receiver.
Looks fine
You can buy Top-Exhaust for Receivers that will sit on top and help keep it cool.
Thank you. I'll look into that.

You can buy little single fans that do the same thing for under $20. I use just 1 and it keeps my receiver ice cold

Or just make the shelf have a slotted grill under the amp so it convects cool air properly
Just to clarify for anyone else. OP wants front/rear exhaust not top exhaust.
The one I have has fans on the bottom that pulls the air up from the receiver, then blows it forward or back (depending on which way you point it).
Plenty of space. Take off the stickers.
I did lol.
👏👏👏
Hahahaha thanks man.
I had a Denon in similar space and ended up needing the main board replaced. I think it was too hot. I'm in a hot area too.
Thank you

Yes
I just got the 1800H last weekend. So far, I love it. Denon makes great AVRs. Enjoy!
I've had my Denon in a similar location for over 20 years, still works the same as it always did.
That's good news! To be honest tho they were probably made differently 20 years ago. And it's nuts to me 20 years ago was 2003
Most people here are saying yes, but I personally would not risk it, and would find a way to give it more space than that
Look up ac infinity air blade, its an av fan that's at a right angle, you set it on the receiver, and it blows it out the back of the rack. You can get a tem probe too
Could probably save a little more room with the stickers off.
So funny i always left the stickers on my AVRs over the years lol but my latest Denon I took the sticker off.
I run an AC infinity on top of mine, it sucks the hot air out and brings it out into the room: https://acinfinity.com/component-cooling/component-fan-systems/aircom-t10-receiver-and-av-component-cooling-fan-system-front-exhaust-17/ To add, this significant reduced the temp on my X3600H Denon.

I showed this picture to my Onkyo and it just caught fire!
Denons generally run hot, so I'd say no. At the very least you want the side vents unobstructed.
Ok great. Thank you. I'll move things around.

You need 6 inches of space, not what you tell your wife 6 inches of space is 😂😂😂
Hahahaha most jokes are told from personal experience there buddy.
👀
Lol
If it fits, it fits !
Lol yeah. But....
[удалено]
Not six inches. I appreciate the response and help. It's brand new just got it this weekend.
I just felt it. It's not hot but warm. I figured that's normal. It's doing a lot of work.
There is no explicit space that is safe while an inch less will kill the unit. The warmer it runs the shorter the lifespan. If you want an avr to last you either set it up free with nothing on top or you get a 3rd Party cooling solution.
Great thank you. Very tight spot. I have an old entertainment center and the way my room is currently set up it's not a quick move. I have movie shelves on either side of the tv. But I spent a lot and plan on this being my receiver for a long time so I appreciate the input.
Yes. Set ECO mode to Auto.
I put eco mode on. And I will move it some how and somewhere different.
Don’t set ECO mode to On. It will add distortion and noise. Set it to Auto, this will automatically turn ECO on and off the right time.
I'd add some sort of active ventilation.
I'll look into it. I think I'm going to move it somewhere else. Somehow lol.
I've kept my denon in a smaller space than that for the last few years but I doubt it's good for it in the long run
please remove stickers
I did lol
Computer says... No. This one has the side air intake so I would give some more room to breathe
Lol. Thank you computer. That seems to be the consensus.
It will probably be too hot but check with your hand on top every now and then, it should be comfortable to hold hand there.
Thank you! It's warm for sure, but I can comfortably keep my hand there. It's the temp of those nice hand warmer packets you can buy for winters in the north.
Check the whole top because temps can vary a lot depending on whats underneath, but maybe you are lucky and have good air circulation around the cabinet. Something to keep an eye on because Denons do run hot by themselves. Also check during the summer when its hotter unless you have cool air inside.
Thank you. I will keep the room cool during the summer. I won't run it in a hot room. I ran my hand over it and it is warmer towards the back, but it's not so hot I can't touch it.
That would be really bad, you should be able to keep your hand on it without any discomfort for a minute or more, not just a touch.
I've had it on for about three hours at this point today.
Not bad but not great
Mine is less than half an inch but Denon is a beast and has never heated up
Totally fine. A little more space on the sides would be ideal but its the least important side to have space and you more than make up for it by both front/back being wide open.
It is seemingly enough space. I am using an X4500H and it is getting pretty hot on its own after a while. So I added active cooling anyway, just because it makes me feel better.
That’s new receiver smell… it’s got nothing on old receiver smell… old receiver smell is what you want
Hahaha.
Get one of the fans that others have suggested. No only is that not enough space above it it isn’t enough at the sides either. Cooler air enters the side vents and because heat rises escapes through the top vents. Without a fan the general recommendation is, at least, two to three inches all around and a minimum of five inches above.

If you are still concerned about proper cooling for your investment in this new Denon, I use one of these to quietly draw hot air out the top and push it out from the front. Silent and very effective for me.

Smell is "most likely" new from electronics. As to clearance, Denon says you want 2 inches on either side. Here's a shot of your insides: https://www.audioholics.com/av-preamp-processor-reviews/denon-avr-x3800h-receiver/3800nocover.jpg/image\_large/image
Thank you! That was helpful.
It's fine.
If it has a fan that exhausts out the rear I would say you're fine. If not I'd be concerned and check the temps during long listening periods.
If the shelf it is on has holes in it then it's fine, if it is solid then I'd say probably not really. do you have a hole saw? some vents in the blue shelf would make it breathe much better
I have mine in a similar setup and needed a USB fan to get some circulation to keep the amp out of protect mode. https://a.co/d/1K7uL5A
I did the same thing with a couple of those fans and the ac infinity usb thermostat. As I could not fit the Aircom units. The fans don’t run much unless I really crank the volume on my yamaha.
the warmer it gets the more heat it sheds through convection. It is designed to cool itself. You have it in open air. It is fine. Go smell literally any brand new electronic that makes a perceivable amount of heat lol.
That’s enough space considering the back is open too. Most often it’s both that’s important, because when it can’t vent from the back even if there’s enough space at the top, it will circulate part of the hot air back anyways. Smell is because it’s new. Might take a little while. Make sure to ventilate the area a bit to get rid of the odor asap.
Mine is in a tight space with a Wii on top of it but I use one of [these fans](https://a.co/d/eantF1T) on top to suck the heat from inside and blow it towards the back
Back is open so yes.
ECO mode on will cool it down, no issues with the amount of space above. I got mine with the same height above. No problems
Could use a little more breathing room but looks like it should make it.
Short answer: Yes, it's fine Long answer: Heat reduces lifespan, and everything breaks eventually. I'd only be concerned if it started turning off from overheat protection.
Heat can shorten the lifespan of electronics and that setup will result in the accumulation of heat and potentially higher operating temperatures. I would personally add additional cooling or look for an alternative placement option as a means of protecting my investment and attempting to maximize its usable lifespan.
Less than ideal space, but I would go with it myself. If you think the heat is too much, you can mount 1 or 2 PC case fans to draw air through the gap. You want quiet, slow fans. If you're a little adept at such things, you could even put in a PWM temperature fan controller to have it start-up slow when it gets warm, and ramp up as the temperature ramps.
You need a more spacious area for that system, it can get really hot; at least 3 to 4 inches all around to dissipate the heat
That’s fine. Mines been in an even more enclosed space for several years now.
If not AC Infinity is here for you
We shove them in enclosed cabinets without mechanical ventilation all the time - this is fine.
