    Has anyone else on this forum had problems with an Onkyo TXNR801 getting hot? My wife has been watching the TV all day and when I got home I could not touch the top of the receiver. I have noticed that it gets pretty warm sometimes but never this hot. I guess it could be the cabinet that it's in. There is a glass door on the front with a vertical opening down the middle of the cabinet in the back. Do you all think that this is enough ventilation or should I add a fan to circulate more air through the space? Thanks for the comments.

    In the advanced Setup menu ... switch the speaker impedance to 4 ohms from the default.

    That should greatly diminish the heat output.

    I wouldnt do that (unless you had 4-ohm speakers).

    Your wife uses the receiver all day too? I didnt know you needed surround sound for soaps and talkshows.

    Yeah...
    I've got an Integra DTR 8.3 on my HTPC - hooked into Energy speakers ... I tried it and it's quite a difference.

    Thanks for the help guys. After you said something about the Ohm setting I went and checked and sure enough it was set at 6. My speakers are some older Klipsch KG 3.5's and their impedance is listed as 6 but just to be safe I set the receiver at 4 ohms and man did it make a difference in the heat generated. Are there any drawbacks to using this receiver at 4 ohms on 6 ohm speakers?

    Thanks again for the responses.
