How quiet is this while it's running?

quiet but it emits quite a bit of light from the top and side of diffuser. Difficult to use in a bedroom.

Faint noise. Used in healing center with some background music. Not bothersome to me.

The fan is definitely not loud and is actually pretty quiet, but always runs. I have this in the bedroom behind the TV and definitely put it into sleep before bed because you can hear the fan. It would not bother me when awake even if on the desk next to me. The hard drive is amazingly quiet, possibly in part to the rubber grommet mounts.

Pretty quiet. These units don't work by pushing a lot of air, so the fan is relatively small.

I cannot say for 100% certain. It seems reasonably quiet (certainly NOT silent), but I'm running it in a server room with a couple of servers that kick out major decibels, so I don't have an accurate sense of this machine's noise level. Sorry.

It is quiet, but you can hear it running. It might be a distraction if used intermittently in a home theater environment. I have no way of measuring actual decibels.

It is quiet. Just a quiet low hum so you could have it under your desk and would probably hardly hear it.

You can hear it when it is on but it's not really noisy. I would call it fairly quiet.

It's very quiet. Not at all noisy. My daughter forgets it is on because you can't really hear it.

Not bad. You can hear it running, but we also use it in an agricultural setting, so it is not very noticeable. All of these size refrigerators make about the same sound, I would say it is fairly quiet.

About average noise when compressor is running quiet when just the fan is running

I have it in an office waiting area setting. It does not seem to make much noise, its actually pretty quiet. Hope it helps

It's not too loud. Certainly much quieter than some of the larger HP units in our neighborhood.

It's very quiet. If it's cranked slowly it should be nearly silent. It won't bother anyone.

Mine is quiet until it is under load. I use it as an alarm clock to wake the kids for school. Can't use it on weekends until after 9am.

it isn't very quiet when running. however, I plan on using it mainly for power outages, so the loudness won't be a problem. And it will be running a ways from the house. If you are concerned about loudness, such as for a campsite where it would be run daily, you might want to check the data on several before purchasing one. hope this helps you.

It is not whisper quiet. You will know when it is running. I have it outside of the house and when I am indoor with all windows and doors closed, I can hear it. Nothing too crazy, but can be heard.

It is pretty quiet. It sounds like a quiet fan blowing. Nothing more than that.
