    My 722 keeps locking up from the Texas heat. So my options were to turn my AC up, move my 722 out of my upstairs, or plug in the Thermaltake MobileFan II External USB Cooling Fan. And presto, the fan works great. You just plug in the usb to the back of the receiver, point the fan in a direction of the holes in the side and the temp drops. I have had no issues since. The cost at frys was 14.00.

    The Targus coolmat has also been discussed as being a good solution. The 722 would lay on top of it and it also is powered by USB.

    What if you have an external hard drive connected to USB? Would the fan still work if connected to the front USB while the HD cconnected to the back, or vice versa?

    Both USB post are equivalent.

    Good idea.

    It can work better than the typical laptop cooling pad, IMHO.

    That would work great I bet! Couldn't find one. Thanks for the link. I have 2 laptop coolers. One on the bottom, and another on the top. I added a powered USB hub and never hooked it up except the power part. I am using it to power both coolers. I had one plugged into the front, but it looks sloppy with the cable hanging out of the front.

    To answer the one question, yes you can use the front USB for a fan, and the back for EHD. I had that set up for a while until the bottom cooler seemd to not cool it enough and I needed 2 laptop coolers to keep up.

    Not to belittle your idea but the Thermaltake USB fan has been discussed
    many times in here as a successful method.

    The laptop coolers may help a little, but the motherboard covers most of the bottom of these units, so to get cooling on top of the MB, you need to pull air out of the left side of the receiver.

    I recommend the usb powered fan.

    I have an AC powered fan from Hometheatercooling.com (pic attached).

    It was not cheap ($49) but it has been running 2 1/2 years 24/7/365 and still going strong.

    It also blows over the EHD to keep it cooled down.

    The fan is really turning, the flash just stopped the motion so you could see all the west Texas dust on everything (I need to clean that again!).

    I have the same fan and I've found it works best if its placed at the rear left side (looking from the front) blowing out. I had it on the right side and it made no difference in temp. When I put it on the left side, the top of the box was no longer hot to the touch and the Diagnostics page showed a 15 degree temp drop.

    I finally bought one of these yesterday from a Sams Club near me http://www.samsclub.com/sams/shop/product.jsp?productId=179203 I know that this is bus powered, but I am thinking of getting the optional Targus AC Plug for Targus Chill Hub. I have looked at the specifications and I can't seem to find out how much this increases the available power, however. I am guessing that it might be roughly 500 milliamperes, but I can't tell. It looks like the fans will work okay with bus power, but I might use this hub as a place to plug in a USB for other charging purposes. Plus, there is a Promotional Code http://www.retailmenot.com/view/targus.com to get 30 % off. Anyway, does anybody here have the AC Adapter and, if so, can you check the device to see what the power rating it?

    Targus Chill Hub
    So, 500 mA max anyway by a limit from PC specs - you could use ANY new PS adapters (USB connector, 5V) like for cellphone/Kindle.

    I would suggest getting a 2nd fan. Put one on the right blowing in and one on the left sucking the air out. Here in AZ my cabinet can probably get to 110, as it backs onto the garage.

    I have two vip622 and one vip722 and haven't noticed the heat issue yet.
    I have the eastern arc so all my receivers are MPEG4 decoding now so I would think it would be worse. I ordered the fans anyway. Thanks
    My system is only three days old so not a lot of history

    I have the VIP722K and was surprised the fan ran all the time. Even with both receiver sides turned off. I woke up this morning with the room temp at about 65 degrees F* and the fan was running with the receiver power off. So I have plugged my Targus Laptop fan underneath it, and we'll see what that does. My HDD shows high temp of 140F and low of 75F. Guess maybe this will help.
