Receiver Additional Cooling

Hello,

My Yamaha RX-A760 is about 2 years old and in a fairly tight cabinet. I can feel the heat radiating out of the cabinet and on the top of it. I need additional cooling.

I bought this fan to help: Size: 4.7 x 4.7 x 1 in. | Airflow: 65 CFM | Noise: 18 dBA |. I have space (about 2.5"W x 7"H) to place it upright to the left of the receiver where it is vented. There is not enough room above the receiver to place this fan. My questions are:

Should this be sufficient in assisting the built in fan? And,
Should the fan be blowing air in or extracting air out of the receiver to assist with cooling?

Because this is my first post, it won't allow me to attach a picture of my setup or a link to the fan.

Thanks,
Volksball

I assume the back of the cabinet is open, is that correct?

Only with a hole for wiring.

Thanks for replying.

These work really well and are inexpensive and relatively easy to install.

Thanks for posting that. Yeah, I've seen those. The issue here is, cutting into my cabinet. I'm looking for a quick, but effective solution, if there is one. If not, that would be my next step.

Based on your recommendation, you then would suggest that the fan extracts the air, rather than blowing into the receiver?

Thanks,
V

I am not positive but I don`t think you really want air blowing into the receiver.

If it fits on top of your receiver get the one that exhausts air out the front, either the s10 or T10. It looks pretty tight in there though.

Honestly I would put the AVR on top of the cabinet but maybe that's not an option for you.

That environment will shorten a units lifespan. If the back already has a hole, either make it bigger or cut the whole back out.

Yes I have an Aircom T9 right on top of my Denon 6500 and 2 Airplate T9 in use. One at the bottom drawing cool air into my AV rack and one exhausting hot air at the top.

Ok. Thanks. On top isn't really an option, so I'm trying to find out the best workable solution. I'm open to installing one of the fans on the side of the cabinet, but trying my best to avoid carving it up if I can help it.

Maybe I'll try the fan I purchased to see if I can extract hot air and exhaust it out or the front of the cabinet.

Ah ok. Good to know. I've got to figure something out quick, then. Thanks.

I had an A760 that I bought for a friend. she had it in the cabinet with little ventilation. Eventually the HDMI board went out and had to be replaced. since then she leaves the cabinet doors open and everything works fine.

AVRs need ventilation badly or it shortens their life greatly.

I learned that the hard way as well on one of my first Onkyo receivers that only lasted 18 months luckily it was under warranty but ever since then I always make sure I have some type of fan pulling air out

You will have to cut the back of the cabinet! I didn't want to either but realized it's either aesthetics, or a receiver burning up because of the excess heat. You don't have to cut a lot just enough to exhaust the hot air inside. My Infinity worked much better after I made a larger hole. Is it only you that doesn't want to cut the hole, or a significant other complaining?

The latter will likely happen.

I figure that if I cut a hole behind the receiver, then it can be visually covered by the receiver itself, and I can use one of the below fans to exhaust out the back and one on the vented left side to exhaust out of the front?

Should that help?

Edit: I didn't see the picture at first.

You cannot make that receiver work in that shelf. You can replace one of the two now, or you can replace the receiver when it dies. No amount of forced airflow can fix this problem.

Front-to-back cooling works in a server rack because servers have ventilation at the front and they have baffles to direct the airflow inside. Receivers don't have any of that. You literally cannot make cooling work front-to-back in a receiver.

Other people are trying to be helpful by giving you suggestions, but unfortunately they aren't really good suggestions.

Air should flow in one direction from cool to hot to out. With that cabinet being open at the front, the cool air starts there and should exhaust out the back as high as possible.

Thank you, Scott, for your good advice. I'll make that work.

And thanks for your condescension, Dono. Hopefully someone "enlightens" you soon. If I had all the answers, there wouldnt be a reason for me to post here. Hopefully your questions are met with the same level of helpfulness and understanding.

You might check to see if you can easily remove the back panel of your cabinet. Depending on the cost and quality of the furniture it may just be a piece of 1/4" veneered particle board held in place with screws around the perimeter. If that is the case you can replace it with black 1/4" foam core poster board which is easily cut to size with a utility knife, and so can also easily incorporate cut-outs to allow passive airflow or fan venting, such as an AC Infinity.

I long ago did this for my cabinet, installing 12V computer fans and a personal computer fan controller to regulate the speed and noise level for all my components in various sections of the cabinet.
