I don't think we should be buying extra fans etc to cool this thing. DISH should have done a better job designing this an internal fan or better electronics to make it run cooler. I don't like fan noises when watching my movies. It really kills the experience when you have very good HT system. HD quality is definitely not as good as DirecTv. I hope they correct it soon as well.
The Thermaltake fan has a variable speed you set to level you want. If you crank it up, you will definitely hear it though!
