Hi everyone, I have been wondering for a while now is there an average operating temperature on the HR series such as does an HR20 normally run X degrees while a 24 runs at Y degrees, on average. Under normal conditions.

If you don't mind posting the series/model # and internal temp of your individual STBs and any out of the ordinary conditions ie. In an enclosed cabinet, ect also approx ambient temperature would help. Keep in F° unless you note otherwise.

Thanks I will pour over and average out the data if enough is compiled
Thank you for your time as well.

HR21-100: In cabinet(amp below,dvd above) avg 106-109
HR20-700: free standing in bedroom, when lying flat 127,when standing on side(been this way for 4 yrs!) 109...!

You're going to come up with quite a bit of meaningless data unless you standardize the ambient conditions. The internal temperature of a receiver depends highly on the external temperature (and even humidity), system activity, along with the fan system used to cool it.

It would be better to establish a listing of internal temperatures over some limited external range (say 65 to 75 degrees F), and better yet to take the internal temperature at a given external temperature such as 70 degrees F.

I don't want to dump water on your goal, but just listing a group of internal temperatures and the receiver type isn't too scientific.

By the way, my HR20 has an internal temp of 104 degrees at an external temp of 70 degrees F.

I understand that ambient is a variable, I'm not trying to get a end all be all number. I am actaully just looking for trends. I'm not trying to be Mr. Wizard here, participate or don't.

Anyway. Have a HR23-700 @ 111°F in same conditions as above. Same room actually. 75° F ambient.

It remind me statistical report from a hospital - average patient's temp is NORMAL :D

I don't see any meaning in such poll. You must know your HDD specs (mim/max and recommended temp) and create such condition for YOUR device/HDD. Lower is better - 40 degree C would be good for start.
Just keep it at that level and don't waste your time and time of other ppl. ;)
Dont worry about my time. You just wasted yours typing that out, other ppl can decide for themselves if they want to waste 5 minutes.
Im not looking for HDD specs, I don't need them. I also did not create a poll thread.

I am simply asking other people with HR boxes to post some simple information, either politely post it or don't.
I'll share what I do with it at a later date if anything comes of it.
I am also going to keep posting personal findings as i come across them unless someone wants to lock the thread who has the power to do so.

HR34-700 = 106° (sits atop an AM21 on open-air shelf)
HR24-500 = 102° (sits on open-air shelf w/AM21 far away)
HR22-100 = 102° (AM21 sits atop it on open-air shelf)

All of the above taken w/ambient of approximately 70°.

BTW, potentially interesting thread, so ignore the thread crappers---they, like trolls, should never be fed.

My HR20-700 varied from 120 to 127. I never bothered to measure temperatures for my HR21. Both units were partially enclosed, i.e. an open front.

And My FiOS DVR is cool to the touch. Both DirecTV units were warm, but certainly not room heaters.

My HR20-700 always ran 127 degrees with the room temp at 78. About 18 months ago the fan started to get noisy and the temp started creeping up to 129, so I replaced the fan, the HDD while I was at it and blew out 4 years of dust and it has been at 125 since. It is in an open front only enclosure.

That is very illuminating. Of course if you put a flat board against the bottom feet as they extend from one side of the chassis with it on edge, you will probably get a similar number to flat.

It just goes to show you that physics works. Having more ambient air flow available plus the chimney effect is bound to lower the temp; its just a little impractical for most of us to stand our DVRs on edge.

Another way to lower the temp that is somewhat practical is to move that air by force, which is why I have a 5" $9 Walmart fan pointed at the rear of each of mine. I also raise them up a bit by placing the cap from a water bottle under each foot to get more air underneath.

(Do you have to turn the TV on its side to watch it now? :D)

The cooling solution varies from model to model. For example a Hr24-500 has a rear mounted exhaust fan while a hr20-700 has a vertically mounted internal mid mounted one and I think the 20-100 has its fan mounted flat on the bottom of the chassis its also a larger fan as well.
The 24-100 has no sign of a fan but I have never opened one up either.

My HR24-500 reports 126 Degrees but I doubt that this is correct and it is in an Enclosure but I keep the doors open with a fan blowing on the back.

However, I do have a 2 TB Internal Hard Drive in my Owned HR24-500 so that could make a difference.

Your HR20-what? The 20-100 and the 20-700 run at different temps. The 700s run at 123-126 degrees. Put a WD EADS or EARS on/in it and the 700 runs at ~ 118 degrees.
