Onkyo RC360 - How much space needed above?

post #1 of 6
Thread Starter 
So I purchased a Onkyo RC360 receiver and wanted to place it in my DLP Stand.

Similar to this
Stand

Because its so tall, it only fits on the 1st shelf. There is then about 1" clearance between the top and the 2nd shelf glass panel.

Now my basement is nice and cool as its on a slab but do you think thats too small of space? My only option is to take out the top shelf and rearrange everything to give the Onkyo nice ventilation.

Thoughts?

3 to 4" minimum. I'd moved those shelves if I were you. Onkyo's are/were known for heat issues. Newer models are supposedly cooler but why take the chance.

One inch doesn't seem like enough space to let it breathe. But you can give it a try - see how hot it gets with that much room. If you can't lay your wrist on it after an hour or so of a good movie you'll have your answer.

If it has a full inch above it that might be OK IF IF there is no back panel on the cabinet and it is completely open to ventilation front and back.

The rule of thumb is that if it gets too hot to comfortably put your hand on at any point for 10 seconds, then it is getting too hot.

Another thing to consider is how much heat is going to whatever is above it; is there anything up there that is a concern?

It is completely open front back and sides. so that is not an issue. I would place a comcast box directly above it so that wouldn't be an issue.

I am torn. I know the new units have what looks like a 120mm fan on top but that might push air up and right back down.

I owned an HK AVR 520 for about 6-7 years. It ran hotter than any receiver I owned before or since. The best cooling solution I found was to mount a 120mm fan above and behind the AVR and pull the air off the top of it. Trying to push the air over the AVR causes the hot air to dam up inside. With 1" to work with you should think about adding a fan in that manner.

Take a look at some of these fans - one of them should do the trick for you. I would not buy a fan that sits directly on the top of the AVR - there would be nowhere for the hot air to go. Just let the convection cooling do it's job - and pull the hot air off the top and you should be fine.
