My latest temps with my $7.50 external dual USB fans that blow into the left side:
100F High
82F Low
87F Average

Mine are also taken with the room temperature around 67-68F.
Why do you seem so surprised at my lower temps? I've included in my various postings in this very long thread all my temps, including before and after going to my "engineered"
fan solution (post 566 this thread). The temps are staying pretty stable, and haven't varied more than a few degrees up or down.I don't see the temps making any great changes, even after summer comes along. I'm quite happy where they are, and don't have any plans to do anything different.
Because of the placement of temp sensor. See my post about LM75.
I could imagine when blowing into right side 'cool' ambient air will affect reading the temp by 622, but by your choice the air flow coming backward - from hot parts ( thru PS, then chips, then HDD ) to the sensor area. Fishy.

Say what you want, I don't need to prove anything to anybody, and I have no reason to lie about it. I simply want my receiver to stay cool, so as not to have heat related problems. I'm seeing the temps I stated with my fan mod, and I've shown you a picture of my simple fan mod. I don't care why it works, it just does.
You know, my fans don't cover the whole perforated side, and are separated from each other. When they blow the air into the left side, there's nothing on either side of the fans, and the open middle area between the fans that stop the air from going inside the receiver, and then blowing back out the same side. Maybe that's what's going on, I don't know. Go back to my post 566, and look at the pic of my fans again, you'll see how much of the vent is still open, and not covered by my fan. You can't see the far end, or the middle space, but the fans are centered, so you can imagine the rest.
That just proves to me that nobody needs to go to extreme mods to cool down their receiver. It's cheap and fast, so nobody is holding anybody back in trying it themselves.
Do you have DMM with thermocouple ? Or better Fluke 52 ?
To check temp at right side a couple inches inside ?
PS. Please don't take this personally - just imagine, we are working in same EE lab on different ideas on same equipment; we got different results - lets verify them, recheck everything. I'm just looking from engineering perspective.

Hummmm, I used to have a older meter with thermocouple used for checking temps in stoves and such. I used to be an appliance tech, and used it for setting temp setpoints. I haven't seen it for some time, but I know it's around somewhere. I've have to try to find it, or see if I can borrow something newer from work for a couple days.
By the "right side", I assume you mean the side opposite of where I have the fans blowing in? I just want to make sure we are on the same page.
722 running 138 high/129 avg/122 low
I've got a 722 unit in a pretty tight Pottery Barn cabinet. Our first 722 lasted 3 months before the hard drive fried (DN sent out a replacement unit). Initially we saw audio out of synch and the picture would freeze on certain recordings - other recordings worked perfectly, then we hit a complete hard drive failure.
Dish Network were not helpful with the replacement. We lost an entire month of recordings - I asked for them to waive a month of fees but they refused and said we should be grateful they're even paying the shipping on the replacement unit.
Our second 722 is only a month old and looks as if it's following the same pattern - audio skipping and freezes - I fear that we're days away from another HDD failure.
I checked the temperature diagnostics and get:
High: 138
Avg: 129
Low 122
Based on this would you experts out there say my problem is heat, or something else?

Those temps are entirely too high. You MUST do something to lower the average to 100 or below, or your receiver WILL fry!. Read the last few pages of this thread for ideas.

I had my 622 running at those same temps. Never had any problems, but after reading some of this long thread, I decided to spend $8 on an awesome little fan. I slid the cover back about 2 inches, being careful to not have it touch a black part that sticks up--if they touch = sparks. I attached the fan to the rear USB port on the receiver, and placed it face down on that newly created 2 inch gap. After 10 minutes, I touch the cover and it is very cool. Temps are down to 80's. The fam is a Thermaltake USB standup fan--got it at amazon. Dont bother placing any fan underneath the receiver, b/c the motherboard will block the flow. Or you can try the solutions that Paul and primestar suggest.
I wrote E* to ask why my receiver is always on (and thus the usb fan). They replied that the receiver is always busy doing something (defrag, updating guide, etc). That it is normal and ok to have high temps and to constantly hear the annoying fan noise of the 622.
My temps are about the same and I have some signs of problems with the older refurb: spontaneous stopping at 4:12 AM MT, and possibly some disappearing recordings.
I have never seen the EHD doing any "defrag"--it just keeps space inaccessible until you have a smaller file. It seems only to respond to the poor/rich man's defragger, i.e., copying all out above the holes and copying them back--very time intensive.
The internal HDD may defrag but how long it takes, I don't know. I do know that the space left is often larger than recordings can be placed into it. It is hard to know the space in MB left on the internal (hours are not a good reference, unless someone has the conversion factors), easy to inspect on an EHD.

Forgot the loss of keying to multiple EHDs on that 722. -K

Too Damn Hot
My waterheater doesn't even run that hot. Get some air moving around that unit are it will go belly up also.

The fan keeps the unit cool or at least trys to .The unit needs enough space for the air to pass through the receiver ,sucked in and blown out. The unit can tell you its temp.through the system dianostic screen in the menu. MENU, then 6,1,3, con`t. If the unit is deprived of adequate air flow it will cause the fan to work harder. Heat issues can damage the harddrive in the unit causing problems with the unit`s functionallity.Closed spaces not recommended without additional air flow source, ie; cooling fan in the ENT>center etc.
[QUOTE]Well, I had a "tech" come out to look at mine, and we plugged in a new unit to compare the noise of the two. They were similiar in noise levels. I just decided to keep my unit.
Don't know if the temps the CSR tech thought were high are a factor, but the "tech", if you can call 'em that, didn't seem to be concerned. He was more concerned with my cable connection in the wall... I was like, wth??? does that have to do with my dvr fan noise.
He said he is required to look at "sleeve" connectors at the wall?? Sounded as just a reason to write up some labor/service charge to me? He didn't strike me as well informed at all.
After he knocked over some stuff trying to look at it, I told him to leave it alone, as I'm in the "don't fix it if it isn't broken" camp and was kinda gettin annoyed by that time.
Sorry I had wasted our time with the call. But if you want your wall connections looked at, bay all means, send for a tech....
His motive for that was most likely because if you do not have 3ghz barrel connector coming from the wall plate or there is rg 59 cable coming from the wall plate to the receiver it will cause your system to lose signal in the future.
The new generation dish receivers generate 18 volts to the LNBF .Anything less than RG 6 cable and 3ghz wall plate connectors will fail .
He was just looking out for his TC rate. If he wanted to get paid for being there for nothing all he would have to do is say he did something .

Hi, do you know what is considered a Normal Running Temperature ? Also what is the Normal Stand-By temperature. Got our system a week ago VIP 722 did not subscribe to the High Definition. Unit was in a homemade cabinet with screen doors on the front and completely open back, moved unit to the top of cabinet and the temperatures "feel the same", but will check them using your Post. Thanks for taking the time to share your information, Skip
Guys. I have a very noisy 622, and have thus researched the fan issue to death. As stated above, off means standby, not truly off. ACcording to Dish, the device is always updating the guide, defragging, etc; busy little bee. My fan is on constantly and it is very frustrating, very. They designed a metal box that has internal components that get very hot, yet they decided to only put slits on the side that are partially blocked by the components. Hey Dish...heat rises!!! You need openings at the top!!! The ones on the bottom are useless.
As far as temps...there is no acceptable range. According to Dish, my average temp of 128C is normal and acceptable; I never had problems. I bought a Thermaltake $6 portable USB fan (amazon), stuck it to the left side vent blowing in, and temps have dropped to the 90 range; the box is cool to the touch. However, since the device never powers down, that external fan runs all day; I am not sure if it was designed to do that, so I unplug it when not watching TV.
I think we all have to accept the high temps, and try to block out the damn fan noise; it is a loosing battle.
