On amazon I found a dual usb powered fan, which i am going to power from my xbox360 as the reciever has no native usb function, but any usb powersource would work.
these perticular fans have rubber gromets that come with them to dampen vibration and noise and I am planning to put them FACE DOWN on the grill directly above the hdmi card.
I know most people say they need to be face up to draw out the heat, but my thoughts are that airflow directly over the culprit cannot hurt and it will still force air out the front of the grill. it will be a couple days till they show up, but I wanted to offer it up as a solution, i think they are $20 on amazon.
Ok, now I have had my fans in place for a little over a week, and I can confirm that they make a DRAMATIC difference. they are nearly silent, and I discovered something a little unusual, the xbox 360 new black 250gb version has the USB ports powered full time, even when it is off, at least the front usb port i am using, meaning the fans run 24X7 but they are cheap enough I would gladly replace them once a year or so. the important part is that they cool the revciever even when using other devices.
the specific once I got are about $20 but well worth it:http://www.amazon.com/gp/product/B00...00_i00_details
I did not do the thermal measuring step but by touch the chasies is now about 25 - 30 degrees cooler even when fully powering all 7.2 and upscaling.
I placed the fans [comes with dual fans] directly on the grill. it is pulling the hot air out of the reciever and is so silent i can barley hear it when right next to reciever. the fans also come with rubber feet so make it even more silent, but I found they are quiet enough without and I wanted a flat fit to draw the most air out of the reciever. now I can play it for hours on end and have little or no temperature gain.
having already replaced the hdmi board myself and thorwing away the old one before I heard about the thermal paste, it is a mistake i do not want to do again. I highly recomend something like this for anyone using the tx-sr707. If you dont have an xbox 360 you can get a plug in usb adaptor for $3 or $4. a very inexpensive and not technically demanding way to prevent what so many of us have already foud to be a significant issue.
