Can I remove the feet from my onkyo 805?

[Jeff R.]

I bought a new stand and my onkyo 805 will not fit, by like 1/32". If I take off the feet it will slide in and I think I can squeeze a small cooling fan on the top of the unit to cool it. Do I have anything else to be concerned about?

Thanks

Jeff

Many receivers and amps are built to dissipate heat by passive convection. Hot air always rises. The feet under a receiver allow cool air to enter under the receiver as hot air rises from the top. Removing the feet will block this air flow pattern. A cooling fan on top might or might not work well.

Can you cut air holes in the shelf and place the receiver above them?

you could, but you shouldn't. air circulation goes from bottom (colder air) to get exhausted from top vents
Block bottom and you restrict air circulation. Not great idea with warm running 805

I'd say no. From what I read, even with the feet removed there won't be a heckuva lot of room on top to allow for air circulation. Between that and the bottom being right on the flat surface, it's a good recipe for fried oinker. Now, I love bacon as much as the next guy but not in this case.

I'd say it just ain't gonna fit in there and move on.

Thanks guys. Appreciate the feedback. I guess I will keep looking for outside the box solutions.

What if I shorten the legs just a little. There is some open space above, the shelves are open frames with glass shelves, so I have about 3/4" of open space on top plus the glass also leave small openings also.

You said "open frames with glass shelves". Does than mean the sides and back are open?

If those sides and back are closed, ¾" space above the receiver is less than I'd be comfortable with. It might lead to overheating. I'm going to guess that the owners manual suggests leaving about 4" (10 cm) open space above the receiver.

I say, let him do it. I think subconsciously he wants to upgrade the avr to newer model

The owner's manual says (on page 2 item #18):

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.

BSA does have a odd point...if it dies. I will not cry.

The opening is the framework the glass sits on roughly 1 " thick so there will be some breathing room. Especially if I use a fan to force air flow...I am going play with options before I set it up. I can always put it on top. But that is where the center channel speaker was supposed to go.

 

[Jeff R.]

Yes sides and back are open

Put it on top of the sub with a thin sheet underneath. That's where I keep my amp.

Skip the sheet and get some of these!
