You're lucky - no 100+ F outside and poor A/C in July there. Anyway 100F is good temp for the HDD - just slight fever by human scale.

I'm new to Dish and have already fried one DVR, most likely due to temperature (was running at 104/123/140). I'm putting my A/V equipment in a cabinet under the TV. The cabinet is enclosed. Right now, I do not have air coming into or out of the cabinet. After learning of the temperature issue, I've used two of the USB Thermaltake fans. I have these blowing into the front right side of a 722k and blowing out of the left back side.
I have a few questions:
1. How often does the temperature counter update? Is there anything I need to do to update it?
2. What average temperature should I aim to be under?
3. What is the best place to put fans around the DVR?
4. The Targus notebook pad fan is on sale at buy dot com. Has this item worked well for cooling the DVR?

If you have a chance and patience you need to read this whole thread. All your questions will be answered.
Supermatt,
I've have read the entire thread and generally have tried everything. The notebook coolers (I have 2 Targus and will sell them to you if you want) work but they are loud enough to be heard in a normal room. Steve P's fix is the best but it requires extensive modifications to your DVR.
The side USB powered fan didn't work at all for me... Don't know why.
What did work and is so silent that you have to put your ear within 6 inches to hear them going is the following from Coolerguys. They have 2 120mm fans and like the Targus you just sit the DVR on top of it. There are bottom slots that fans will blow cold air into and it works great.
In fact, it works so well, I bought another one for my stereo rack. Wedged it between the top of the amplifier (pulling hot air out the top vents) and sat my Apple TV (that puppy gets hot!) on top of one of the fans after I put some small stick on feet on the ATV.

That looks like a neat setup. I think I will try it out. What did you get your DVR average temp down too?
If you search for my posts, you'll see the back left, pulling out, fan that worked, and then you'll see my newest config with the top off and fan blowing down.
Current temps:
Low: 86
Avg: 93
High: 105
I think the counter updates every night with the update. It may not always change but I think its slow reacting. If you "reset" your dvr every day, you'll get the numbers down faster because i guess it wipes that clean or something.

Thanks guys, good stuff.
Another note: I'm using a usb hub with success to power the fans. (This has probably been mentioned before, but figured I'd share in case it wasn't.)
Before dropping $60 on that comcool fan, I think I'd attack the circulation in my cabinet. I'm thinking a fan like this:
120VAC 4" Fan - RadioShack.com
hooked up to an attic thermostat:
Thermostat,Attic Fan - Line Voltage Thermostats - Controls - HVACR : Grainger Industrial Supply
so it doesn't have to run all the time. Only downside is I'll have to cut a big hole in the top of the cabinet behind the tv and hope the fan isn't too loud.

I have had the Thermaltake fan on my box for a week now and the new numbers are
High 131
Low 86
Average 114
So my low went from 107 to 86 and my average went from 123 to 114.
The fan seems to be doing the trick as the top of my box used to be hot to the touch, now it is cool. It is just on the left side of my 722 sucking the hot air out.

They have solutions to that to!

I have the 1st one in my upstairs cabinet as it has a glass door. The flat model sits on the bottom of the DVR blowing cold air into the DVR but I had to find a way to exhaust the total volume inside the cabinet. So I put the dual 80mm on the back and they work great. Creates negative pressure in the cabinet so cold air gets sucked in around the glass causing a vortex.
I don't see what is wrong with a 4" PC cooling fan, just find one with a lower db level. Mine runs @12VDC 24/7 and even in a quiet room, I cannot hear it.
You also have to realize that your temp readings are from the Hard Drives INTERNAL temp sensor, so it will take some time for it to come down. It also averages the temps over a couple months.

:
Start by putting it into a small apartment sized refrigerator with cable holes cut into the back for access and putting an external UHF antenna and converting remote 1 to UHF. Then you could possibly see numbers like:
Low 36'F
Average 38'F
High 45'F
:haha:haha
