I have a Dish 722DVR that as the title states runs really hot and has the fan running all the time and far more often than my second receiver that never makes a sound. In the morning during the reboot that it automatically does it will stick and will have to be manually restarted to get it working. I have tried plugging it into different outlets and a variety of other options that were suggested to my by Dish. Is it possible that the fan is defective and needs to be replaced and causing issues. This is a replacement receiver that I got from Dish a little over a year ago. I would not let it bother me other than its in a bedroom and continually wakes me up during the night and its frustrating when it gets stuck in the reboot mode. I had it even suggested that it was the reboot that was waking me up. I can confirm the reboot is not the problem as I have it set to around 9 am.
