is it loud when it runs or does it run quietly?

It's very quiet. It only makes noises when you carry your laptop with your right on the fan.

This unit is much quieter when it is elevated by the extention legs. Otherwise, I find it is noticeably running but not objectionable.

It's not super loud when it runs, but you can definitely hear it. However, when it starts breaking down a few months into use, it becomes REALLY loud.

It's pretty quiet. I wouldn't record webcam videos and stuff with it 'cause it does make background noise, but it's not bad at all. About the same as any box fan. The one thing (that's been mentioned in several reviews) is the USB cable has a tendency to get pushed into the fan blades a little bit, at which point it makes a high-pitched grating sound, but tug on the USB cable gently from the back and that's solved quickly. It is a tad unnerving though.

I find it very quiet, and the noise it does make is subtle and not grating. I have other brands that are much louder and didn't cost that much less; I recommend this one. Note: it's tall - elevated my laptop noticeably, which works well for me in terms of more comfortable using the keyboard (it's the thinnest & flattest laptop I've ever owned), but something to keep in mind.

It is not loud. I use it outside but it is well insulated but has no tank so it does run continuously

Not loud or noisy at all, just the regular treadmill noise. My wife has been using it for a while now and she loves it

The noise level is based on how fast you set the fan. On the lowest setting it is pretty quiet. Even on the highest setting it isn't that loud.

It's quiet. I wouldn't count on it as a "noise muffler", if that's what you're asking. The blower/fan doesn't really make much sound, but if you have the dial turned up high, you will hear the sound of water dripping occasionally.

Fan runs only when needed. I have 2 units and both are very quiet even with fan running.

It is a quiet fan, it sounds like a dryer vent when running from the outside.

It's quiet on the low setting but the high setting is a little loud for me. Just my preference. I like to keep it on the lowest setting.

Noise is different to each person; however I find it to have a normal motor sound which is not that loud. I run mine in an enclosed garage, checking on it periodically.

It does make some noise when running but is much quieter than previous units I have owned. I would estimate between 40 and 60 decibels when operating

It is very quiet. It does have a fan and occasionally it is loud if the computer is "working hard". I would say the fan is on very low 90% of the time and you can barely hear it.

It does make noise but its not that loud. I have it right next to my desk. when its not running it is silent.

Mine is relatively quiet; it only makes some mild fan noise when under heavy load.

Its pretty quiet. I run it at night on the lowest speed while sleeping. It's not silent, but probably the quietest fan I've owned. During the day, with more ambient noise, I hardly notice the fan is on, unless its blowing on me.

It is not really noisy. It makes a swoosh sounds as you walk or run on it -- but not noise.

Mine is super quiet. I have to look at it to make sure it is still running.
