High and low, I drilled a bunch of ventilation holes into the back of the entertainment credenza. By going both high and low, doing so improves convection air flow and when driving the unit particularly hard, to improve air flow further, I open the cabinet door a few inches during movie viewing.

How much free-air clearance do the L/R sides and top cover have?
You should have at least 4-6"...
Anything less can impact the AVR's reliability..
Onkyo AVRs run hot due to their high-biased amplifiers.


Just my $0.02.. wink.gif

Parts Express and other places have fan coolers you can place on top. Probably worth checking out.

The Onkyo TX-NR3009 has 4x the power of the 391, so it runs hotter.
Kinda like comparing a 1.4L 4 cylinder to a 6.4L supercharged hemi.. biggrin.gif

Buy one of these. http://www.antec.com/soundscience/AVCooler.php
Works well with my 809, although I never had a heat issue with it. I don't want to take any chances.

Don't buy that one. Try the com cool cooling station with dual 120mm fans. Can be found on amazon. Will cost more than the wanted. Better airflow and reliability than the above mentioned. Or look through the 3009 thread for some cheaper and/or better options.

butter and jelly please.

He already bought it so you are saying send it back & get a Denon AVR 391?
I bought the 3009 because I wanted the 9 channels.Isn`t 391 is just a stereo receiver?
