    I currently have an HR20-100. Have a 1.5TB AV hard drive in it. Recently replaced the fan. Still running at 130 degrees. How hot does the HR24 / AM21 run? BTW, you still need the b-band converters for the HR24, correct? Does the AM21 have any quality / performance issues vs. the HR20's built in OTA? Is the integration seemless like it is with the HR20?

    you need BBC only if you are not using SWM. I have not checked my HR24 temp, but IIRC it runs about ~125. The AM21 integrates the same as if you were using the built in OTA tuners in the HR20

    I just got a 24 and AM21 to replace my HR-20. I looked once at the temp and IIRC it was 120° inside a closed cabinet. The AM21 works much better than the OTA tuner in my HR-20.

    My HR24/AM21 combo is currently at 111 degrees - which is about normal. Bounces between 103 and 115 from what I recall.

    I get identical OTA readings between my HR20 and my 3 AM21's on other DVR's....it might depend on what type of signal issues you may experience in your area, like multi-path, etc...I seem to remember that the tuners chips in the AM21's were pretty much the exact same chips as in the HR20....because people criticized the you know what out of them when they were released because they expected a newer device to use a newer gen chipset on the tuners.....

    Its always possible that more recently built AM21s use a different tuner chip than older ones. If the tuner chip they were using when it first came out is no longer available, they would have had to replace it. So the people saying the AM21 is no better than older receivers / worse than a new TV and others saying they're similar could be both right, depending on the manufacture date of their AM21.

    My HR20 was dieing a slow painful death that affected the OTA

    The normal temp for a 20-700 is 123-126 degrees F. 130 degrees won't hurt it.

    Just checked two 24s for temps. One 24-500 sitting in the middle of a stack of 3 HRs is running at 117 degrees. That one has an internal 2TB drive. The other one is a 24-100 with an external 2TB drive that is running at 102 degrees. Before anyone asks, the HRs in the stack are separated by one inch spacers.

    I have it in an enclosed cabinet (glass doors). The heat has already damaged 2 pieces of equipment. It was sitting on top of a VCR and the HR20 cooked the LED display. So I replaced the fan and the VCR and it cooked the second VCR's LED display in about a month. There is also build up on the glass doors from the heat.

    Crazy. My AV equipment is off for most of the day. All other components are ice cold in stand by mode. Yeah, I get none of them do anything in standby while the HR20 is always working. Recordings are pretty minimal. I just updated my todo list for the next 2 weeks and I have about 34 items.

    I can cook an egg on the HR20.

    Want to replace it before the 3rd VCR commits seppuku from the heat.

    When I had a HR20, it woud run 125-130 deg. My HR24-500 (on top of a AM21) currently shows 108 deg., which is typical. The hottest receiver I have had was a H20-600.

    I usually take the glass doors off the cabinets and use a 3" hole saw to punch a lot of holes in the back cover. Never saw a need for the doors. Do you put spacers between components? I've got two 24-500s sitting on top of a 20-700 and they're not overheating.

    If your HR is really that hot, it would shut itself off. What does it tell you?

    After I replaced the fan the last time, it's consistently running at 130 to 140 with the doors closed. It did overheat / shutdown a few times before I replaced the fan. When I went to pull it out of the cabinet, I noticed it had cooked my VCRs LED display. No room for spacers with the HR20.

    I recently had it hanging out over the edge for about 20 mins as I was servicing another component and when I went to check the temp, it was in the 90s, so I guess spacers would probably help.

    Without spacers I'd think you're gonna have these problems. I really have to wonder why the makers of these entertainment cabinets don't take the heat components put out into consideration when they build them. I've never bought one that I didn't have to modify. They also don't take wiring into consideration.

    That 20whatever model it is needs air circulation. That's why it has so many air vents on the top and sides.

    Interesting, but I've never seen the need for that many fans. Nice to see I'm not the only nut running around with a 3" hole saw. Hole saws have come a long way since I used my first one. That hole saw actually had to be put together each time it was used. Now they come in one piece. Much easier to use.
