Does anyone else cool the 622 the way I do? I just pulled the Entire ac plug off the wall surge protector and all. The 622 never really cools off even if you turn it off. I am doing this at night. I should be just fine right?

I've been doing this because I've had quite a few picture freezes and no signal last few days. My connections are fine.

Unless you 622 is defective or you have it in a place where there is no air circulation your problems are probally caused by something else besides heat.

DON'T unplug your 622 at night. It gets its guide information and performs other functions overnight. As far as the heat, yes, the 622 does get fairly warm. As long as you don't block its airflow or put it in a closed in equipment cabinet it should be fine. As Steve said, you could have some other problem. If it continues it have problems call tech support.

MY 622 has lost power twice this morning. Dish is going to send me another one.

I've had hd service less than 2 months and have had to replace both my 211 and 622 and replaced the lnbf or whatever you call it.

Hmm, sounds like you may have other issues. Something doesn't sound right here.

That's for sure. If you've had problems with two receivers and the dish hardware... I think you had a bad installation. Maybe you have a grounding problem, or power surges.

Good luck sorting it out!

I plugged a small watt meter into the wall outlet then plugged the 622 into the meter. It draws about 50w whether it's on or "off". Warm air always flowing out the left side is normal. The unit needs a few inches of space around it and the warm air needs an escape route. Be sure it's not too confined in your shelf or cabinet. I also raised mine off the shelf about 3/4 inch to improve circulation below it. Walmart or any hardware store sells (usually in a 2-pack) round rubber door stops. These are the kind that stick to the wall where the doorknob would strike. They are about 2" in diameter and have a rubber cup like affair that is about 1/2 " deep. In this application they don't need to be "stuck" to anything. Get 4, pull the line cord to let the disk stop spinning, then lift the receiver and slide them under it and you will notice that the existing feet on the receiver mate perfectly with the cup shaped opening. I watched the temp guages in the menu and after several days noted a decline in the average temperature of the receiver.

Put one of these underneath your 622. I have with both of mine, and it cools fantastic. It simply plugs into the USB jack in the back of the 622. They are on sale this week at Office Max for $19.

Thanks for the advice I am trying that right now. The 622 gets as hot as my plasma and we all know plasmas gets super hot at times.

Do you know what it's called, or a link to more info?

Also, how loud is it?

Thanks,

This is what I use. Standing vertically on the left side of the 622 to pull air out. It is designed to run 24/7 and with a 1 year warranty against workmanship defects. <29dB.

It is a Targus Notebook Chill Mat. They are not very loud at all. Plus I think they are more aesthetically pleasing than having a case fan mounted on the side. ;) I do have mine tucked more underneath than calgary2800 does, though.

The chill mat is working so far. Its been 12 plus hours and no freezes or outages. Prior to that I think I have 8 to 10 failures of the 622 in a 2 day period. Its makes a big difference just on feel alone at the bottom, the 622 now is much cooler.

The Chill Mat is an interesting option. Is it audible from ten feet away?

My 622 and my other gear are in an enclosed TV stand, but I have three fans like Jim's running inside. The only issue is, the fans are triggered by heat from my 7-channel amplifier, which means they only turn on when I watch TV or listen to music for a while.

If the 622 gets hot even when it's off, it's going to be hot quite a bit when the fans are not running. I could put the thermometer on the 622, but then it would run almost all the time and may not run when my amp needs it most.

I've had no issues with noise with the chill mat.

I may be wrong on this but I think if you need to cool down the 622 either something is wrong with it or it is in a too confined place.

If this unit plugs into the USB port, does it run when the 622 is turned off(Does power still go through the usb port). I am having a big problem with heat and need to consider this solution.

thanks,

The 622's USB port is on full-time, so the cooling mat runs full-time.

the chill mat is a great idea - I've been using a muffin fan just as described here and raised my 622 up 3/4" w/ a couple of strips of 1x2 ... lots of air pushed into the left side and underneath.

my first impression of the 622 is that it's undercooled. in a perfect world dish would overbuild the cooling but not this time.

I've only had the 622 for a week, but I am very disappointed in the amount of studdering/fragmenting of images thus far(Way more frequently than my DirecTv system(noyt HD) - I do have the 622 in a cabinet without good airflow and its hot, so I am hoping a cooling fan will help with my issues(As others have reported) - otherwise I will be calling Dish
