John, take a look at the link in my sig. I'm using an 8inch silent external fan from radio shack. $12 if I recall correctly. It keeps my receiver ice cold.
I have it blowing up to suck the air out as others have already stated. The fan is extremely silent if standing up by itself but does make a small humming sound when placed on top of receiver from sucking the air so fast throiugh the vents. Unless you are really anal about or are trying to listen for it, you will barely notice it after awhile.
I listen to my movies loud so I don't even hear it except for extremely quiet scenes. Again, it is a very faint sound. I had to splice an AC cord to it (since it is made for computers or electronics I believe) and plug it into the back of the receiver so it turns on with the receiver.
My HK avr630 runs hot with the M80's. Until I ever decide to run seperate amps for the fronts, I will be sticking with this option.
