Wow.
I'd like to have a clever question for you, but it really just makes sense. No problems with a fanless 8500 then, eh? I've got a 7500 in an HTPC, and have long wanted to pull the fan off, in favor of a 80mm Panaflo being pinted at it instead. Looks pretty obvious now that it would be plenty.
Sorry - not trying to ask a question in your post
Great job and nice writeup.
