My 7700 is in a cabinet that is closed. I would like to have a small fan or 2 installed in the cabinet to blow cool air over the top and/or a fan to suck the warm air away from the top, or both.

Does anyone have any suggestions or references?

I have a StudioTech stand and they sell a lot of fan options for cabinets, including some that are thermally triggered. They are not the only vendor, but you can see a lot of the options via their web-site.

I didn't buy fans from them because I created my own thermally controlled fans the cheap way. You can buy the rack mount cut outs and mount 12VDC fans to them, using the 12VDC of your pre-amp to trigger a relay for the fans. Then, I use the old down and dirty mercury switches that were common to older homes, cause I had one lying around, inverted it and then wired it as the swith for the fans from the relay. I just rotate the mercury switch enclosure to change the turn on temp. I have a non-contact handheld thermometer from RayTek to help me spot check the temperature.

If you're looking for off-the shelf, and don't want to build one, a couple of suggestions: ATM products and Cool Components at one of my favorite web retailers. The cool components cabinet vent fans are an easy way to get the air in & out.

Another thought: I have a USB laptop cooler inverted over my DVR, which has 3 USB ports. Works great.

However, like Alphanstein, I prefer to DIY the fans. I recently started using USB, which carries 5v and up to 500ma, to power some vent-mounted 60mm 12v fans in my cabinet (2 pushing, 2 pulling), USB via the x360. The lower voltage makes them run slower, but much quieter, and they run constantly.

My hat's off, Alphanstein, to your innovative solution.

cp1966,
I added a cooling fan to an old setup i had. I found an AC computer fan (120v) on the web and ran w/ a dimmer switch for speed control.
I happened to also plug in a small light for a little ambient lighting.
worked really well.

I found some, Thanks.
