Is this switch fanless? how loud is it?

Not fanless. I could be wrong, but I don't believe there are fanless PoE switches with these many ports. The power output warrants cooling. With that said, this is a fairly quiet switch--not silent but not noisy either.

There are two fans on one side. It is a bit loud. Fan noise is high pitched.

It is loud for in office installation. The PoE+ needs to be cooled down properly.

It is about as "loud" as my desktop computer. All you hear is a slight "breeze" coming from the motor's fan. It isn't bothersome at all.

The fan cycles on and off. But it does make a noise when on. I have is sitting right behind my work desk where I spend 8 hrs per day and I never think about the noise. I would guess 35-45 db.

Not at all. It is the least noisy of any fan heater that I've owned or that I've seen in other's houses. Can be used in any setting - office, bedroom, nursery, etc. - without being distracting.

I suppose your sensitivity to noises would determine whether this fan would be considered quiet or not to you. I would call it moderately quiet on high speed and quite quiet on lower speeds. I keep it on medium speed and the small amount of noise it puts out is not at all disturbing and the fan is located in a bedroom. It is used only in the Summer to boost air conditioning. The unit is turned up-side-down so that it throws air up. it works perfectly well that way and still responds to the remote control as it should.

No. It is basically just and on/off switch which is activated by plenum/duct pressure. I also bought a fan that has two speeds so that I could control the air flow in the downstream duct.

Yes, it is very quiet. It has 3 fan speeds. I have it in a bedroom, so to make it even quieter I put a strip of heavy felt on the sill to cut down on the compressor noise.

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.

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.

It is somewhat louder than the single fan in my new Mac Pro, which is almost inaudible. It's really pretty quiet, although I have no way to measure the actual decibel output. I do hear the hard drives within when they spin up, and also when they are accessing data. I am not bothered by the "noise" at all.

I returned that fan as soon as I got it. It wasn't what I expected at all. Sorry, I know nothing about the switch. It was a long time ago, but if I recall, it was most likely an electronic switch. It was not the best quality fan, somewhat bigger and not very powerful, if I am remembering correctly.

Relatively quiet. It's definitely quieter than the last fan of similar build I used.

Unit is quiet. No fan noise is noticable. We have been satisfied with its performance to date. Have had for about 4 months

It's more like a very small fan. I'd say it is relatively quiet. It's not a rattling sound or anything. I usually use mine at night so it's ready by morning.

Yes, this fan is plenty loud. I bought it because I like noise when I sleep. It fills that purpose.

Yes very quietly ... A little click when it shuts off. You can't hear any noise when it's running .

I don't think it's noisy at all. The only noticeable sound I can recall of comes from the fan, still quite discrete.
