I'm using 120mm fans, too. Silverstone. Very quiet.

Heh. I just (oh, 11 months ago...) pulled a pair of 120mm Silverstones out of my case in favor of the much quieter Scythe fans. Of course, I'm sure my Silverstones are a different model than yours.

I just stopped by BB today and picked up a 120mm fan and wired it for the old trusty H/K. Maybe after running the AVR635 for five years at scorching temps it will make life easier during the golden years, but with my luck it will overheat and blowup during the first day of use with the new cooling fan ... 'cause that's way I roll.

It's a BB brand fan, 'Rockfish Gaming' and it seems very quiet so far.

"Silverstones" sounds like an old guy's balls.

Because......?????

Just how empirical are your findings?

Ha ha. Either you're playing along too well or you missed the lameness of my joke.

That's just frightening.

The brand is Thermaltake, it was from RadioShack. The rating on it was 21dba. Sitting 12 feet away I can't hear it run.

120mm fan from Monoprice works great and is quiet enough. Much better than the two I had before of 80mm size. Splice to 12v adaptor and plug into AVR switched...done.

Ken, I think a lot of the perception of "quiet" also depends on the other devices and the noise floor in your room/home. Between the hard drives in the computer and DVR, the filter in the aquarium, the dishwasher, forced-air heat, etc., I'm not going to be challenging ANYONE for a optimal listening experience. But, you know, I live in the real world. No projector, no man-cave. On the other hand, I have a shared viewing experience with my family basically every day.
