    My HR 24-100 suddenly has what sounds like a noisy internal fan.....either that or the hard drive is making a lot of noise. The device is working perfectly and I've run a system check and performed a reset on the device. Everything tests fine. Anyone else had this issue?

    Now it's totally quiet again. Internal temp is 106 , so no temp issue. It's working perfectly, so I'm just going to ignore it.

    I've heard the HR24 fans go into hyperdrive mode at times. They can be quite loud. They seem to have multiple speed and generally the super-fast (loud) speed goes away quickly.

    That must be it, Doug. It's been totally quiet for a while now. Thanks.

    My HR24 500 is quiet, but my HR24 100 seems to drop into hyperdrive and become noisy randomly each day. The device tests are all fine though and the internal temp is about 106. As long as the thing isn't going to catch fire, I can live with the noise. :)

    When I got home from work today, the DVR was quiet. I checked the internal temp and it was 143 degrees!!! What? It's never been above 109. How does it jump to 143?

    The device is well ventilated. I decided to reboot it. The device went into a self imposed cooling down mode, and it only came up after it had cooled itself down to 120 degrees. The device continued to cool down and quickly went back to 109 degrees. It has been at that temp for several hours now.

    Just as it was coming up, I called Directv to report these events. The CSR seemed totally unconcerned, and her view was that the device would sort itself out.

    Has anyone seen anything like this? The CSR seemed to think that I was overreacting. My worry is what caused the jump in internal temperature? The DVR is sitting in a ventilated entertainment center in an air conditioned room. Nothing outside the box has changed.

    I have to admit though that it has been quiet and cool at 109 degrees for several hours now.

    My plan is to keep a close eye on the device. Anyone have any thoughts on this?

    Sounds like the fan didnt kick on when it should have and the unit began to overheat.

    Has the fan continued to work? I got home yesterday, and my daughter told me to "fix the TV." The blue circle light was just spinning. After a a hard reboot, I had a blue screen saying that the internal temperature was like 145 deg F, above the max. internal working temperature of 140 deg F, and that it needed to cool down in order to function . . . so I unplugged it and waited. After it was cool to the touch, I plugged it back in and rebooted, and now I get nothing. No fan sound, no self-check, nothing. If I leave it plugged in, it gets quite hot.

    I called Directv, and they are replacing the unit (but not until Tuesday, which really sucks on a free HBO/Cinemax weekend . . . sigh). Mine was an HR21-200. We'll see what I get. But I too had a well ventilated area, with no obstructions to the side vents at all and never a problem at all with heat in the past. So, keep a close eye on your unit, just in case.

    Hyperdrive is very hard for the HRs to regulate. The dilithium crystals might be breaking down. Beam me up, Scotty!.......:lol:

    Ever since my HR24-100 performed its self cooling down process, the temp has been back to normal (106 to 109) for several days now. :)

    Based on my own testing hard drives start to fail the receiver's short SMART test around about 160 just to give you an idea on how hot you got.

    Having a process that regulates fan speed has its drawbacks as that implies that the process can fail on occasion, especially if it is a process running independently on the CPU (which is why a reboot will fix it).

    Maybe it is better to just have a dumb fan that spins at the same speed all of the time; the only thing that can fail there is the fan bearing or the 12v supply. Of course that implies better cooling design so you don't need a 2-speed fan.

    BTW, the "jet" sound description sounds very much like what an Intel 2500 server sounds like at startup, as it cycles its fans to top speed for about 20 seconds.

    Mine is super noisy, you can hear that thing working OT from time to time, think thats what causes my audio drops too. You can be watching something and out of no where you lose audio. Change channels and all is fine. On recorded shows when audio drops I have to rewind a bit and its fine.

    Are you getting audio drops that are not accompanied by video stuttering or breakup? While common a few years ago, that is very uncommon as of late, and is usually not indicative of a reception issue. Audio drops (usually with video issues as well) can be from a number of sources, including a faulty HDD, but the noise issue is probably a separate issue (which does not mean the HDD is not at fault, of course).

    The fan on my HR-24-100 runs all the time. I turn off unit but still runs. It is loud enough I have to unplug it at night time. I do not remember it running like this in the begining. I worry it will over heat. I am not tech savy and don't know how to check temp or anything. Need to know if this is normal. It does this even when not recording.

    I can't help you much. But I can tell you that I have a 24-500 in my bedroom and it is very quiet, as is the good old 20-700 on the shelf below it. I can tell you that it's not normal for the fan on your 24 to be that noisy.

    The fans on all the HRs will run when you put the unit in standby, that's normal. I don't know if the 24s have a control that shuts the fan down and turns it on when needed.

    In any event, the 24's fan shouldn't be so loud that it annoys you.

    My HR-24 started making fan noise about 2 months ago. Tonight I noticed a small red light flashing on the front and switched to that box from another. The screen said the temp was at 147 and the system had shut down until it reached 120* It has been running about 109* since then.

    I would think the fan shut down completely and caused you to get the high temp reading. We've seen a couple reports on threads of the same thing happening. I believe the heat sensor is on the internal HDD, but that doesn't account for the fan being noisy.

    Is it noisy when the temp is 109?
