You guys don't have to butcher your Vip622/722 to get low temps! I considered using P. Smiths method, but I didn't want to cut into my 622, and I think that's overkill anyway. Plus, you better not do that to a LEASED receiver. I give all sorts of honor to P. Smith for all the work he did, but I think it's far more than the average person needs to do to cool one of these receivers.
I now get MUCH cooler temps, it only took me a short time to cobble this up as a prototype, and it works perfectly! I could make it prettier, now that I know it works, but why bother? Here's what I did:
I had a Targus laptop chill pad, that I bought at a "2 for 1" sale. I got 2 of them brand-new on sale for less than $15 US. I took one of them apart, and stripped out the two thin 4" fans, and the wiring, complete with the usb cord. I plugged them in to make sure which way the air blows OUT.
Then, I took a regular metal coathanger, and used bathtub silicone caulk to glue them to the hanger, slightly apart, and so when I taped the hanger flat to the top of my VIP622, the fans would hang down from the hanger, and cover the air vent on the left side of the receiver (if you are facing the front) Think of this as sort of an "L" shape, with the fans forming the lower bar, and then the "L" laying down on top of the receiver. The fans blow INTO the receiver, and are plugged into the front USB jack. I did this over 1 month ago, and have been tracking the temps. It has been stable on these for that time:
100 TOP
89 Average
82 Low
Very quiet also!
My Vip622 is mounted into a fairly tight cabinet, and only has about 2 inches of air space on each side. It sits on top of an old Dish 6000 receiver (turned off, unplugged, would not be easy to remove it from the cabinet)). Above on another shelf, is a JVC HM-DH30000L D-VHS vcr (That thing is HUGE). Sitting on the JVC vcr, is a FTA receiver. Sitting on the FTA receiver, is a DVD player. So, kinda hot in there normally. By the way, all these are sitting on top of plastic 16 ounce pop-bottle caps for extra lift to their feet, as they are cheap, and give more space for circulating cooling air.
There is a 4" hole cut in the bottom left rear panel (facing from the front) of the cabinet. There is another hole cut in the top right rear panel for exit air. I used to have a filtered high-speed 120volt muffin fan blowing INTO this cabinet 24/7, at the lower right corner. Hot air would then rise, and go out the top hole. This kept the VIP622 at around 105-120F or less (before the muffin fan, it was at 140F!). Now, these cheap fans from a old laptop cooling mat, keep it MUCH, MUCH cooler, and I removed the muffin fan (WAY, WAY too noisy!).

The "!" = fan side view blowing into vent, the number "1" is the side of the receiver. This doesn't format quite right, but it's just a quick diagram showing what I did.
BTW, primestar31, you better make a picture to convince us if not that ugly as we can deduct from your description
.
Well, it is UGLY, but is in a cabinet, where it isn't seen. I did say this was a cobble-job prototype for now, as I was testing it, before making it "pretty". Now that I know it works, I can make it look nicer. Biggest advantage, is it doesn't violate any possible warranty. I own my receiver, but people who lease shouldn't cut holes in their's, and my method takes care of that.
I have now included a picture, as I was at work last night when I posted this, and didn't have my home pc. By the way, the muffin fan you can see in the back rear of the cabinet, is the older 120volt NOISY one I used to use. It's no longer plugged in, but I didn't remove it yet, until I was sure this new method worked fine, which it does.
