So I just got a new Onkyo TX-SR313 receiver to replace my old Onkyo. The new one seems to run so hot that it shuts itself off periodically. It's in a component rack that is completely open on all four sides and has several inches of clearance between the top of the unit and the next shelf up.

At first I thought I might have a short in one of my speaker wires. I checked all of them and they all seem fine. My next step was to just place a floor fan down in front of the unit to see if overheating was the cause. With the fan present, I had no more shutdown problems for the rest of the day. Once I turned the fan off, the unit shut down again in less than half an hour. Fan back on, no problems again.

I obviously can't keep a floor fan laying on the ground to keep the unit cool. Does anybody have any suggestions for other cooling solutions, preferably inexpensive ones? I also would like to avoid too much fan noise, if possible.

Check out this site for solution for your problem. If they don't have it, you don't need it. Good luck.

Thanks for the link. It looks like just the place I need.

After looking around for a bit, I think I'm going to go with this:
http://www.coolerguys.com/840556090557.html

It seems like it should be quiet enough. Plus, since it is powered over USB, I can plug it into the front USB port of the receiver and it should automatically switch on and off along with the receiver.

Does anybody have any comments or suggestions about going with this? And when I do get them, would it be best to place them on top of the unit on opposing corners, pulling the air up from the unit?

Place both on top, one on each side where vents are with fans drawing air from the AVR. With this placement the fans will be drawing hot air from the avr and cool air from the sides or bottom. Good luck and hope this helps. I've used some fans close to these for my older Onkyo 876 and they kept it cool even when running it all day.

Thanks. And after checking Amazon, it seems they carry the same items, but with free 2-day shipping. So it ends up being a cheaper solution than I was expecting. Here's hoping it works.

They will work just fine. Just make sure when you install them that they are pulling air from the avr and not blowing air into the avr. Let us know how they work please. Info will be helpful to others using Onkyo avr's.tongue.gif

Well, they should be here tomorrow according to Amazon. I'll set them right up and see how it works.

Are Onkyo's known for running a bit hotter than most AVRs? I know my old one got pretty toasty, but then again so do most AVRs.

They do have a history of running hotter than most. Or I'll say the models I know did. The newer ones from what I've don't seem to have this problem. Could be true or not.

So I've had them hooked up for the past couple hours. So far, they seem to be working great. They're almost silent, yhey turn on and off with the AVR since they're powered by USB, and the unit has gone from hot enough to shut itself off to being nearly cool to the touch.

Good job. Hope they continue to work for you.

Mine is a June 2013 revision and it does run quite hot, for being a basic unit compared to my 818.
