I know there are a lot of older threads about Dish receivers/dvr's getting too hot. Just wondering if Dish has done anything about this. Just had my 722 replaced at just over a year old because of apparent hard drive failure, probably because of it getting too hot (high temp was up to 140 and average was in the 120's before I turned on the laptop cooler I had under it which cooled the average temp to about 105... but I guess it was too late). Mind you, the unit is basically sitting on a bookcase shelf and not in an enclosed area... the tech that came out to check on the problem said that shouldn't cause it to overheat. Anyways, they replaced the 722 with a new 722k. I noticed the design is a little different than the 722 and the fan is barely audible when running so I was thinking that maybe Dish fixed the problem... until I checked the temps. Right now the high is 138, the low is 68 (that was after install) and the average is 111 and has been climbing the last few days . The unit feels a little hot to the touch so I just ordered one of those fans everyone seems to use to keep it cooler so I don't have it replaced in another year. I guess I'm kinda annoyed that there still seems to be a problem and we have to come up with our own fixes for something Dish should have fixed years ago..... /rant.
