Net little cooling solution for AVR

Guy on AVS turned me onto these, pretty neat once I got it setup and the fans are quiet.

Offers an option vs installing the fan inside your stand I guess and I like the idea it doesnt cut on until it senses 82 degrees.

Those fans are pretty cool. I had to move the temp sensor to one side near a fan base because the very middle is cool and doesnt match up with the area over the heat sinks. Just watching some football at normal volume, the fan cuts on for about 1 min 45 secs, then off about 2 mins 30 secs, and then back on. pretty cool.

I assume some heat builds up, they turn on and move the hot air out (can tell it cool with my hand in the air coming off the fan) and then shut back off.
