I have an Onkyo TX-SR700, and I am having problems with it getting very hot. I am a dj and therefore listen to my music loud, and for extended periods of time. I was wondering if anyone knew of a way to keep it cool. I know that there is quite a bit of space inside, and was thinking of installing a comouter fan in it to vent out the hot air. If anyone knows of a better way to keep my receiver cool, please let me know, thank you.
