    I'm skeptical if the H20 can run cooler, going by the heatsinks mounted on the TWO cpu-looking devices inside, plus its hefty power supply. The power supply takes up almost 1/2 of the case's width. I think this receiver has more going on inside than an average desktop computer.

    The designers could have easily designed the case to vent out the heat through the back rather than the top. But, then, we all would have been complaining that the back is too hot, my cables are going to melt, is this bad on the connectors? :lol:

    But, I'm just speculating...

    Whether it vents out the back or top, heat is heat. Like I said earlier, I'm not an engineer so I have to give "them" the benefit of the doubt as far as the design of the box and ventilation.

    There's a certain amount of truth about the complaining. Not insinuating that you are one by any means, but it does seem like some folks on these boards just want to complain about any and everything and they're not happy unless they do.

    Oh, I totally agree. I think the box is doing as designed and 100 degrees is cool enough. To not have low-rev cooling fans inside, it is cooling adequately. But, users are users, and the perception is "hot". Simple notebook styled fans, venting through the back would have the top feeling cooler.

    But, I think the box is venting as designed and doing well.

    I work as an engineer in the semiconductor industry and I can say that 100F is nothing to be concerned about. The semiconductor is a very robust device. Some processes used in manufacturing chips use temperatures as high as 1000 degrees C (that’s 1800+F to us Americans: lol: ). The reason why some chips have heat sinks on them, like CPU's etc. is that fact that the circuit line widths and transistor sizes used in advanced chips are so small that heat can cause what is called "cross talk" and make the chip not behave as it was designed. This is not to say that heat can't damage these advanced chips but if you are not overclocking or modifying you H20 like you would a computer's CPU then I would not worry about 100F.

    BTW - My H20 feels normal to me. I haven't put a themometer on it though.

    does that really work? clever

    now tell me how to ensure the accuracy of a tire gauge

    Yeah, if you want to check the accuracy of a meat thermometer, just stir in ice-cubes in fresh water, stir for several minutes (if needed), and you should get 32 degrees.

    What is fun is to mix salt in with the water in various amounts, stir, note your readings. Demonstrates why rock salt is used when cranking for ice cream.

    Boiling water same way, but when the bubbles just begin.

    Air gauge accuracy. Actually, we did that ages ago in a college physics class. Involved a mercury barometer, a vacuum pump and some pipe that offered "one atmosphere" of pressure. I honestly can't remember the rest... Getting old!

    I'll BET this is the ONLY satellite message group in the ENTIRE WORLD that has referenced thermometers, ice cubes, and boiling water. Boggles the mind! :grin:

    I once had a Houston Tracker C band satellite receiver. The top was too hot to touch, but the unit functioned well until the 2nd year. At that time, some of the plastic connectors inside the unit cracked from the constant exposure to heat. The electonic connections within the connectors failed or became intermittent. I ended up soldering
    the connections and threw away the pieces of brittle connectors.
    My H20 runs about as warm as my old Sony HD300, and it never showed any heat related problems.

    Why only when the bubbles begin? How can water get hotter than boiling point?

    And the tire gauge thing was because my mechanic said my gauge was 8lbs off and cranked it up. Well turns out, his was wrong because he checked against others and found his had been dropped one too many times. I then asked him how to calibrate a gauge and he didn't know. So I got to thinking..how do you know that a gauge is working correctly?

    Heck, I dunno. I didn't claim that the water would get hotter, did I? :nono:

    Probably because in college physics, we were getting impatient watching for the water to come to a boil! :lol:

    Just as you noted... comparisons. But, in our old garage, we could have 30 tire gauges and all 30 would read differently! Hey, it ain't a perfect world!

    I have to change my vote - now that I have it on an open shelf instead of a cabinet with no back it is only 'moderately warm'. as opposed to 'fry-an-egg hot'.

    You mentioned in another post that when you went to "pull it out and reach for the power cord, the thing burned my fingers". My thought was - pull it out from where? Do you have it in a place where there is adequate airflow around it? Or is it in a cabinet or a stack of components where there is minimal air flow? These receivers really should have good clearance and not be tucked away in too tight a place.

    That being said (and I don't have an H20 so I don't pay as close attention as I might for something I do have), I have read on here that one model (-600?) tends to run hotter than the other (-100?). To the point that some have gotten replacements from D*.

    Just a few thoughts.


    --------------

    Follow up - I mentioned, "To the point that some have gotten replacements from D*" before I read the third thread where you mentioned this problem, so I missed the point that you had contacted D* already about it. A fan doesn't sound like a bad idea since you seem to be set up OK for it, but I still would check your location to see that it is adequately vented.

    I'd just like to point out that this "survey" is pointless if the manufacturer code is not included in the info gathered. I believe it's common knowledge that H20-100 run cool and H20-600s run hot.

    the direct tv guy asked me the same thing and I was trying to let him know that there's plenty of room around this thing.

    For lack of a better picture since Im not at home to take another one at the moment, here you can see in this picture, on the bottom right where you see the stack of DVDs that is where my H20 is now (this picture was taken BEFORE I got my H20. On the bottom left you will see my Tivo which is roughly the same size as the H20. You can see theres a good 5 inches or so on top, and 2+ inches on both sides. Behind the tivo and my H20 is another 6 or so inches before the cardboard backing with the hole to let the cables out the back. And of course its open in the front.
    Also just for understanding purposes, you see I have a Tivo, a tuner, and a dvd which all run pretty cool, minus the tivo (which has a harddrive in it), but it too runs way cooler than the H20.
    EDIT: to cut off my 3 extra lines of rant and replace it with this, I think there's adequate space around all sides judging from this pic, use my Tivo as a guide.

    Both of my H20s get hotter than my A/V receiver. That tells me that they are to hot.

    thedonn,

    From the looks of your picture, where you have the receiver located is definitely not the problem. Looks like your set up is very good for ventilation, etc.

    That leaves me with the idea that the H20 model you have must be the 600 and is running abnormally hot as that model is prone to do.

    I'm asking this out of ignorance because I don't own (or lease:)) an H20. Is there a temperature reading in the "System Information" as there is on their other units? If so, what does yours read, and has that been relayed to them when you've talked to them?

    I might go to the point where if I'm not getting anywhere with a CSR, I'd ask to be transferred to Retention and explain to them that you really don't want to put your homeowner's insurance to the test by using one of their receivers that is running dangerously HOT! (But explaining in a nice way).

    They are (or darn well should be) aware of the problem with some H20's running dangerously hot and should resolve it for you. It's a safety hazard.

    Good luck, and let us know if there is any resolution. It's nice of them to suggest you spend more of your money on a fan, etc. but if they are leasing dangerous equipment, it should be their problem to resolve, not yours. And if you can't touch the receiver without it being hot enough to burn you, then it is dangerous equipment.


    Edited to add this: My 3 SD TiVos are running between 42 and 44 degrees C. My 3 HD TiVos are running between 46 and 51 degrees C. Just to give some frame of reference. And admittedly, a couple of my SD TiVos are in a component cabinet and probably not situated the best for ventialtion.

    would the bottle cap trick work on these receivers? (i know on the t60 it helped)

    Do you put a bottle of water on top with the cap just sittting over the hole and wait for it to fly off?

    i was thinking more of elevating the t60 with the caps but if your method is just as effective, i'd suggest trying that also

    Folks,

    Putting some 1/2" thick round felt pads as 'feet' under the H-20 does a very effective job of raising the unit, increasing the air circulation and keeping the unit cooler. Yes, it works.

    These pads are usually sold as feet for bar stools or chairs. It's an easy fix and will save you the pain of being out of business while your 'leased' receiver is being replaced.
