This unit makes no noise, unless it recognizes the loss of its source of electrical power.

I don't hear any noise or hum from any fan. The only thing that i didn't like is that when unplugged or the power goes out for any length of time there is a loud alarm until the power comes back on. Kinda annoying! but that is the only problem i have with it. Otherwise it is a great backup battery for my TV and cable box.

No noise or hum - I forget it's even there unless it's doing it's self test (about 5 seconds) then it's quiet again. South Florida.. we have lots of power interruptions and it's been a blessing.. I know it has saved my computer time and again.

This is a very high quality, quiet unit but you can hear the fan running at times. We actually have it in our pantry, so, we don't notice it, but I believe if you had it in a small kitchen, you would hear a low hum.

As long as your fan is clean, there really shouldn't be much noise under different load mods. I haven't heard that the fan is an issue.

No. It sounds as if you have an installation problem. I have a remote on this fan and it works fine. There is no unwelcome noise.

Not bad, constant hum. There are 3 fans, they do a good job of moving air around. You can definitely hear it but Its never been anything that annoyed me or I even noticed.

I definitely have noticed the fan noise, when I switched to this device from a single-drive enclosure that did not use a fan. But the device was on top of the desk right next to me, and w/o music playing it did create enough noise to make me wish it was quieter. I just moved the unit under the desk, and now it does not bother me at all. As others have said, with 2 drives spinning in there, you don't want to turn off the fan or your disks will be running hot and fail before their time.

I have several of the units and there is not a buzz noise only a hmmmm like a fan. I think something must be lose in your unit. I can put mine on silent and I don't hear it at all...try that....if its still buzzing then something is wrong. They are great units.

You know I had to go and check! However, I have an 828LM and no hum whatsoever. Have you unplugged (the replugged) the unit and tested it away from other equipment for this humming noise?

I have had this unit for almost a year in live application and have not experienced any unusual noise or hiss. I am sure if the gain structure is wrong any unit could have the potential for noise. hope that's what you wanted to hear

Not noisy..but fan cuts off and on every 30 seconds.. does anyone know if this is normal? Only had for 2 months.. It has always done this.

Fan is pretty quite. I use it on camp outs and it does not keep me up. Has low humming sound. Hope this helps.

Could be a defective unit. Mine will sometimes make a very slight hum (ear right next to the unit) but even when I'm lying in bed sleeping other than the reassuring click that it turned on, I can't hear the hum. I also am only drawing... ~11A on the heaviest circuit, if you're pulling more than that it could explain a louder noise

I always install them in an electronics closet so I didn't pay attention to a noise. However, I am actually going to install one today in about 4-5 hours. send me a follow up question and I will let you know if the one I installed has noise or not.

Haven't noticed a hum. We have 3 of them in our kitchen and, even when things are quiet and the lights are dimmed or all the way up, haven't noticed anything unusual. Wondering if you got a defective batch?

Not bad at all. It uses a larger, slower fan to move the air (can kind of see the cut-outs for it on the right side of the unit in the picture). We use it in the garage to drive a noisy high-speed spindle, though, so noise hasn't been a concern for us.

I have only had the unit one night, but the fan noise does seem a little loud. Which is unfortunate because I kept reading how quiet it is and that is one of the main reasons I bought one. Not sure if it is just my unit, or if this is just how normally loud it is for others? Also, my fan ALWAYS seems to be running, even if I am not pushing it hard at all.
