Strange, I did turn a switch on power strip a couple times accidentally and each time 622 after restart did show low values ...

Just checked temps again. No change. Will check again tonight. If hasn't changed will unplug it again and see what happens. My DVR may just have a temp sensor not working correctly. Have no other issues. DVR has been working great.

Wow, nice temps Smith, P. My temps are still the same. I will try to de-power it in the morning and see what happens. Got company and watching recordings the rest of the day.

I stuck mine under my floor, onto a wood shelf that I attached to the joists in my basement ceiling. I installed a coax extension on my RF antenna and ran it back up into my living room. Dead quiet and my temps are 120/96/105. It's been down there for about 18 months now.

One negative of a USB powered fan is that it draws more power off of the 622's power supply and thus generates more heat inside of the 622's box. The net result can still be a lower temp, but it does start at a disadvantage.

current results with open cover and a fan blowing downward onto the mainboard between power supply and hard drive: 104/87/91

I just found the ground and +12V (or +5V, whichever the fan needed, I forget) directly on the power supply and attached it there (non destructively)

Im not too confident of a USB fan either, Im going to give mine a week or so. Prob will consider a laptop cooler next. Im 138/107/125 right now :(


Guess I could always yank the top off, lower temps have to outweigh the dust.

Use an A/C adapter for USB fanss.

Tried another power cycle and the temps are still the same. Had power disconnected for five minutes. I think my DVR temp sensor is stuck. OH well, no big deal everything else works OK. The DVR is real cool to the touch and is working great so I am no longer concerned with it. The latest external fan configuration I am using is the duel fan setup. I no longer use a laptop cooler and have removed the spacers. Here is a link to the external fan.

Ive noticed mine only changes after the 3am update or whenever you have the box scheduled.

Laptop cooler didn't do that much for my DVR. External fans seem to work the best. Check out page 14 of this link for the DVR case vent info.

The ebay fans are pretty nice.


Can someone tell me where the "void" sticker is on the 622/722? Just wondering on the cover because I thought the sticker was on the HDD bracket so that makes it ok to take the cover off.

Three of my DVR's temps change from time to time. I can't pend down when it happens. My fourth DVR temp has been stuck for a long time now.

The "VOID" sticker is on the assembly holding the hard drive to the rest of the chassis.

Smith, P. Guess what? The DVR that the temps seemed to be stuck changed today. Average temp dropped 2 degrees. Yehaaa. I guess it is just being stubborn. Attached are the latest readings.

You guys are spending $50 for something that you can get for $10 on Amazon (Thermaltake USB Fan, high quality, place on left side).

You are also "re-inventing the wheel" as there is a huge thread on this site about this issue, complete with many pictures, suggestions, etc. It's the one linked by P. Smith, but unfortuntely he did not identify what was in the link, so it was ignored by everyone.

PS Laptop coolers don't work so well because they blow in the wrong place. USB Fans don't raise the temperature of the power supply, because the amount of power they use is a small fraction of the total power used by the receiver.

I know this has been discussed before, but I was curious on how some of you keep your 622 or 722 cool? There are lots of different opinions ranging from setting them up a little to get air underneath them to cooling pads or ? Any suggestions or setups? Thanks

Ice water. Lots of ice water.
