As recommended by others, I have a USB Thermaltake Fan sucking air out from the left rear vents of the unit.Do you have your fan blowing into device/cabinet or sucking out device/cabinet?

Do you keep your receiver in the refrigerator?My 722K shows a top temp of 114, low temp of 79 and for an average 107.

That explains it, in your original post you didn't mention anything about two external fans.Nope, I just use this.... Dish VIP 722 / 622 / 612 Dual-fan Cooling System | eBay
On the 722, the internal fan, HD and power supply are NOT in the back. The internal fan is toward the front right side. The HD is in the front center and the power supply is stretching the entire left side.I noticed that the intake vent on the right is only a few inches wide, while the vent on the left extends almost from the front of the receiver to the back. I have one external fan located at the back left of my 722 drawing air out. Does anyone think I would get better airflow if I block the rest of the left vent not covered by the fan? Or would that end up making the airflow even more restrictive? My understanding is that the internal fan, HDD and power supply are all in the back anyway, so I was thinking that I could create more a wind tunnel effect across the components that need it by only allowing air in through the right vent and out the back left side.
Thanks for the clarification and setting me straight on the internals.On the 722, the internal fan, HD and power supply are NOT in the back. The internal fan is toward the front right side. The HD is in the front center and the power supply is stretching the entire left side.
If you block the left front and center vents you will improve the air flow diagonally (front right to back left) but you will compromise the air flow at the left front and center corner. Just keep the vents as is and the external fan at the back left side. You must remember, the HD is NOT the only part that is getting hot there and definitely it is NOT the hottest part. The only reason they are monitoring only the HD is to save money, all HDs have built-in temperature sensors, so it is free. I have studied this overheating problem extensively and my best solution is at post #981.
My exhaust fan is taped over the vents at the back left sided and it is blowing the hot air straight back. This solution is much better that just placing a fan like the Thermaltake at the corner and blowing the hot air to the side. For any of this to be really effective, the back wall of your cabinet must be open and the cabinet spaced a few inches from the wall. My average temperature is now 116°, used to be 128° when the receiver shut down a couple of times.Thanks for the clarification and setting me straight on the internals.
Your solution in post #981, from the picture I can't really tell, but is that mounted flush against the left rear side and then blowing the air straight back (instead of my current fan which is just blowing the air to the left away from the unit)? That would be ideal, as I have a semi-enclosed space with not much clearance on the left but the back is exposed.
Seems like "normal" operating temps for the 722k is HOT HOT and then melt...I had my 625 in a glass door enclosed cabinet and never had a problem. I now have to have the back opened and the front glass door removed with an external fan just to keep my 722 within normal operating termeratures...
