Mine doesn't. Got about 3" space above unit in shelf, no backing on shelf so well ventilated.

Dear Aung,The upper cover of the receiver should get warm within 20 minutes. Could you explain further what you mean by "air ciriculation"? Regards,Eric CohenWorld Wide Stereo

You can't really solve it. The heat is a byproduct of the amplifier. You can search here for USB powered fans that will sit on top of the unit and add additional cooling that work nicely and plug right into the USB port on the front for around 15$. In a properly vented area, without a fan, the heat isn't burning. It's more along the lines of a heating pad on low, or medium after prolonged use. Its only when the unit isn't vented properly that the heat gets to the higher temps of say "high" on a heating pad, or hotter, but even then chances are it won't get hot enough to burn skin unless you hold your hand on it, for an adult at least younger kids might not feel the same. Its worth mentioning that with proper ventilation this unit is fine, after all it wasn't designed to be a grill, it's only through neglect that the heat becomes an issue and even then the receiver will likely break from the heat before it becomes a safety hazard.

Hi, I have only had that happen when I use the unit for an hour of more. I reckon that the quality of the product varies, and your unit may be overheating more than normal.

All receivers get hot to a certain degree. Keep it properly ventilated and you shouldn't have any problems. Also, unless you have less than a 15 amp outlet and you don't have an exceedingly large amount of things plugged into that circuit you'll be fine.

I haven't experienced any overheating issues with it. However, it should have a little bit of airflow around it.

Hello, I have never had a problem with it over heating but I am also not constantly online. If you are constantly online then I am assuming it might become there are no holes for ventilation. Hope that helps

Our receivers do tend to run about 80 degrees above ambient room temperature, this is normal. If you install the apparatus in a built-in installation, such as a bookcase or rack, ensure that there is adequate ventilation. 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. Please make sure that when you turn off the main receiver that you also turn off the Zone 2 because if you don't turn off Zone2 (if your receiver has this feature) then the receiver will continue to run and will produce heat. There is an internet dealer selling cooling fans that can be used with our receivers www.coolerguys.com.

That hasn't been my experience. I leave the cover on all the time - no problem with overheating. I love this cover!

Mine was doing the same thing while watching a movie. After a bit of research it turns out where it was sitting in my entertainment center it wasn't getting enough airflow around it. It was overheating. I swapped my shelves around to get more space around the body and haven't had an issue since. Check that you have enough airflow around it and that the vents in the body aren't blocked.

well, ventilation is always key for an amplifier.So far, and this is after a week, I have not noticed excessive heat.However, I have my main speakers running off a separate power amp via the 773's pre-amp outputs.Both my power amp and the 773 do feel "Warm," but I wouldn't call it excessive.I do have them in an open TV stand with no glass doors and large cutouts in the back.About one inch of space above the top of the unit773 has two USB ports on it, so if I notice excessive heat I plan on purchasing small USB powered vent fans like the ones from "Coolerguys."But, so far I have not noticed what I consider "excessive" heat." well, ventilation is always key for an amplifier.So far, and this is after a week, I have not noticed excessive heat.However, I have my main speakers running off a separate power amp via the 773's pre-amp outputs.Both my power amp and the 773 do feel "Warm," but I wouldn't call it excessive.I do have them in an open TV stand with no glass doors and large cutouts in the back.About one inch of space above the top of the unit773 has two USB ports on it, so if I notice excessive heat I plan on purchasing small USB powered vent fans like the ones... » Read More well, ventilation is always key for an amplifier.So far, and this is after a week, I have not noticed excessive heat.However, I have my main speakers running off a separate power amp via the 773's pre-amp outputs.Both my power amp and the 773 do feel "Warm," but I wouldn't call it excessive.I do have them in an open TV stand with no glass doors and large cutouts in the back.About one inch of space above the top of the unit773 has two USB ports on it, so if I notice excessive heat I plan on purchasing small USB powered vent fans like the ones from "Coolerguys."But, so far I have not noticed what I consider "excessive" heat." « Show Less

My fan is set up to pull air in and expel out the back. Even though my cabinet has a open front, my receiver puts out some heat in a small area (not to mention the DVD, cable box, Roku) and I get real peace of mind..

No, that isn't normal. I have used mine all summer and it never did that. I would contact the seller for a replacement.

I have two of these heaters and never noticed that problem. I don't think it is normal, maybe the wire got damaged. I would exchange it just in case.

I'll check with a thermometer later but it should be warm enough to notice. Also, it takes a few minutes to get rolling. I would suggest flipping the heat switch on and off about half a dozen times; the contacts may be oxidized if it was shipped through a moist location. Simply opening and closing the switch may be enough. I had the same trouble recently with some surge suppressors.

No, that does not sound normal at all. Mine has never heated up noticeably, even when transferring hundreds of gigabytes. Sounds to me like there's something the matter with yours.

Hi Rochelle ~ I've had my up and using it since September and have not experienced overheating and/or the 88.88. I would definitely be contacting the manufacturer or where you purchased it from if it's overheating and get another one. Good luck!!
