How noisy are the fans?

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.

Not noisy. Of course, it is a heavy duty, thus you will hear a humming from the air flow. Excellent fan.

Fan noise is not that bad; at least for the 3-cell, 120 G model I bought. It's as quiet as a normal laptop computer.

These are the performance edition so they are loud if you just plug them in. If you use a fan controller, either external or through your motherboard, then they can be silent while still moving a good amount of air.

Ultimately it depends on the speed you run them at, but these are the high static pressure models not the high air flow models so they are not as loud as those, although even at full throttle neither of them is very loud. These fans are for moving air against pressure; in other words for bringing air into the case.

Very quiet. Can't hear it. There is an option for the fans to be low, medium or high. You can configure to your choosing. Great option.

It is not too loud; about the same as a window fan. I have mine in the bedroom, and I would not be able to sleep if it was very noisy.

For me if I put it two meters away and set it to lowest level, I can nearly heard any noise. But the sound of fans at the highest and middle level are quite clearly to be heard, which you may enjoy. The highest level is loud. Hope this will be of help.

We use ours in conjunction with a desktop computer, so they seem very quiet by comparison. They're small and plastic so there isn't much to rattle or make much noise. :)

There is a slight noise, but in my experience, it isn't louder than the system or CPUS fans, so it's not enought to worry about.

Mine works well, fans are very loud. They sent me replacements haven't installed yet...

The fan is very quiet. I almost did not buy this because someone wrote a negative review on the fan noise. This is not an issue at all.

very low noise . About the sound a small fan would make from a computer cooling system. From 5 to 10 feet away you will not notice it.

Yes it's very quiet. The size of the fans means they're more quiet then the standard 2-3inch fans.

The fans are pretty quiet actually. I Wouldn't find the sound distracting at 12 feet away but I would certainly say you wouldn't want this running in the open in a frequently used room not so much for the sound but the bright colored light would be extremely distracting.

These fans aren't nearly as powerful but are the quietest in the market. All you hear is air moving. Those fans are way loud even with a dimmer attached bit necessary for high powered hids. I use this because I have an led setup that emits basically no heat.
