The fans are relatively quiet and the unit remains vool. No concerns but I need to call the manufacturer to set the timers-they are a nightmare!

They are too loud for my taste at 12v. One by itself isn't too bad, but I have 11 fans on 3 radiators (Two 480s & one 360) and they are very loud. I had to get a fan controller to find the right balance between performance and noise. They do move a ton of air, but are very loud to me. I can't imagine how loud the non quiet edition ones are. I have tried so many fans over the years and a truly quiet fan that can still push enough air through a radiator just doesn't exist yet.

The fans are the loudest thing coming from my rack. This is at home so the noise is a bit much (ignorable). I also have wood floors so the sound travels a bit. I'm actually here looking for quiet replacement fans. I can't find the size anywhere. This unit would not be too loud for a standard business server room.

It's not very loud. I sleep with the ceiling fan on and this thing too, and sometimes I can't tell if it's on. The fan is basically what you would find in a computer tower so the noise is minimal. A slight humm if anything

You can hear the fan when its running, but I don't think it is loud. I put on music when I was using it and I wasn't bothered by the sound of the fan.

This fan isn't necessarily completely quiet but I wouldn't consider this fan on the noisy side either, so if you want a loud fan look elsewhere.

These fans are not quite and are louder than other similar fans of the same size.

The fan is very loud.. I replaced the fan with a whisper fan I had from an old computer.

You can definitely hear the fans running but, I don't find them distracting, in fact, I hardly notice them. Probably varies from person to person though. About the same as computer cooling fans.

I would give them a 2...honestly, the refrigerator in our apartment is louder than these fans, the fans are about a 4 when the computer is initially started, but as soon as they get to their standard air flow, they drop down to whisper quiet.

As far as actual decibel level, I couldn't give you an exact figure but I can assure you that it is one of the quietest fans I have. I actually wish it were just a tad louder because I sleep with a fan that drowns out noise that may wake me. On high, you can hear it, but nothing like your typical house fan or oscillating fan. I hope this helps.

The fans are quiet but not silent. Normally the sound is not very noticeable but when the CPU is under load the fans will spin faster and be louder.

Define "really loud." Mine makes a noticeable noise throughout its entire on-cycle, but it is slightly louder on start-up. If I had to compare the running noise, though, I'd say slightly above desktop fan and slightly below window fan. It's not "whisper-quiet," that's for sure. But, the 'white noise' effect is somewhat soothing, I find. That's just me, though. I hope this helps!

Haven't really used the fans, but when I tested them, didn't find them noisy at all.

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.

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