If your cabinet is open on all sides and with 5 to 6 inches on top, I'd guess that you'll be fine without needing additional cooling.

I just purchased an Onkyo tx-sr805 receiver. I have it on a shelf in my TV stand. The stand is open on all sides and there is about 5 or 6 inches from the top of the receiver to the shelf above for the amp to breathe. The Onkyo 805 is replacing an Onkyo 502 so I know how the Onkyo's run warmer than other receivers. I never had any problems having the receiver setup in the same TV stand for about 4 years. The Onkyo 805 seems to run a little bit warmer, probably because it has a much beefier amp. I was considering adding an external fan(s) with a built in thermostat. Something like one of these. http://coolerguys.com/840556082491.html (also has link to 2 or 3 fan version on this page) or http://cgi.ebay.com/AV-RECEIVER-AMP-120m...1QQcmdZViewItemHow many fans would I need to do the job? Are these reasonably priced items? Has anyone else used these types of items? Thanks in advance for any replies. - Nick I did exactly this for my (first Marantz then 3808) I bought my silent PC fan from http://buyextras.com/cacoso.html and bought the AC (to molex) adapter for the DC fans from the same sight. Works like a charm. The only other thing I did was to buy those fuzzy furniture protectors from Home depot. this way, it doesn't rattle at all.

Nick, if as you say the 805 is just running "a little bit warmer", e.g., no smoke and flames, there wouldn't appear to be a compelling reason to bother with a fan. Running hot may reduce the long-term service life, but shouldn't be a matter of significant concern if the unit is operating well.

Agree with all. If there are no internal fans, any solution should be safe to do. Just check for dust buildup now and then as it will be sucking in more dust than usual and eventually, the dust buildup can defeat any cooling you add. I'd also probably agree with running it a while, as is, before I spent any money.
ON the other hand, I think you should go out and build the first water cooled amp. Trick it out with alien green LED lighting and fluorescent coolant. Mod the case with a see through panel in the shape of an Axiom symbol so you can see all the glow bling. Have the LEDs tied to the thermostat so the more it cools, the brighter the glow.
OK, maybe you shouldn't do that. But if you do, we want pictures so we can make fun of you.
