    My roommate bought a Toshiba HD-A3 HD-DVD player yesterday. We were removing my old DVD player from my entertainment center and putting in the new player. That was when I realized how hot my HR20-700 was. I was quite surprised. Here is a somewhat old pic of my setup:

    [​IMG]

    On the left side of the rack, starting from the bottom, you can see the Xbox, my old DVD player, and then my receiver. When I got my HR20-700 about 4 months ago, I just adjusted the receiver shelf up a bit and put the DVR on top of my old DVD player. There wasn't much room for clearance/ventilation on the top or bottom, but a decent amount on the sides and the back. I have had no problems with the unit flaking out or anything like that. Luckily, the new HD-DVD player has a slimmer profile and therefore the DVR now has about 2+ inches of air flow over the top of it.

    My questions are is this enough ventilation for the DVR? Also, since the DVR gets so hot, will it cause problems with the HD-DVD player?

    Thanks.

    The HR20-700 runs the hottest out of all the HR2x series. Personally I would try and out it on a shelf by itself. Couldnt you put the xbox on top of the DVD player?

    The heat on HR20s is more on the top and the (cooler running) HR21s is more on the bottom. I am not sure about the vents on the HD DVD player.

    Alternatively a small desktop fan on the floor may also help if you are that worried.

    What does the HR show for temp? (make sure you check after your system has been on for a few hours.. as long as your not going over 130 you are safe..

    It's 122*F so it isn't super hot. I was just surprised. Also, I leave it on all the time as well.

    Thanks. I'm not so worried about it now.

    the 700's feel warm to the touch. Too warm for my taste. That is why I am running a Targus chillmat on both of mine.

    It is a computer notebook cooler; you can set it on top of the HR-20-700 & pull hot air from it. Set it inverted so the fans are next to the vents.

    You can get it from Best Buy or similar store.

    Uses the usb ports on the unit to power it.

    Did anyone tell you that behind your entertainment center, it looks like mating season in a rattlesnake den? :D :hurah:

    (Sorry, I couldn't resist!)

    Eric,
    You are fine! I have all of my media equipment in a custom rack that is recessed in a closet...no problems at all....I have both HR20-700's with minimal space between them and my Toshiba HD DVD is located below both....

    Your airflow there looks fine...cable managment would be nice...just for aesthetics...but other than that you should be fine

    Go to the setup menu, press select on the first item on the list, and on the right a long list of system characteristics will come up. Scroll down and you will see the temp listed.

    I think the biggest problem with the HR20-700 (besides running hot in general) is that there is no clearence UNDER the box. The -100 have 1/2" feet to help with that. The simplest approach is to put four small 3/4" 'feet' under your -700. I got a 5 degree reduction just by putting some small blocks of wood under the existing feet.

    105 with a chillmat would be even better. :)

    What is the maximum temp. that is safe for the -700? Mine is at 127F with ambient at 68F. Seems a bit high for such a cool room. It is on a glass shelf with nothing on top or against it. It is also on the bottom shelf so heat from my DVD player on the next shelf up doesn't rise into it.
