I want to know if you should hear the fan blades like they are touching something? I can hear it getting slower till the fan stops. Is this normal?

No. All you should hear is air moving and a very faint hum. Sounds like a bad bearing or motor.

Not on this one make sure it is level thats the only time i hear something beside it is a load fan if on high ...

Absolutely not. My fan makes a whooshing / blowing noise. A "white noise" if you will.

I bought mine second hand and wondered if the fan noise was reason the person sold it. It gets cancelled by the speakers obviously but at rest it is noticeable.

This is normal. You should not hear any sound at all when just the ionizer is on, only when you turn the actual fan on.

I have one of my 5 fans on my receiver, so it is laying flat. So far, I have not hear any noise or vibration of any kind. Only time will tell.

Never noticed a fan problem. I can hear it, but it's quite minimal (and I'm sensitive to noise).

Honestly I can't hear it above the other fans I have in my case, and those are made to be silent as well. It's like it's not even running.

Just one question that should fix the noise .. Have you cleaned the blades of the fans? They will get dirty and in 6 months very dirty.

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.

When 640's fan get to around 60% it gets pretty loud. 3 rd part fans MIGHT reduce the sound because both could spin at a lower rpm. The sound produced when its not doing much is not loud w/ just a stock fan IMO.

My inline Panasonic 30NLF1 exhaust fan is extremely low noise. I have to strain to hear it. I should have added a small light to show when it is on.Buy the highest CFM you can afford.

Mine makes a little bit of of noise, but not too much. I believe it has an internal cooling fan, but I'm not 100% sure on that. Sorry, this probably not that much help.

Watch this video: http://youtu.be/TUaQio67aBE the sound or noise of the blades are pretty much what I hear from the turbine I purchased. Hope this helps.

As with any fan blades rotating, there is noise. With this one, there is a very light humming noise inside the house. On the outside however, you can hear the air blowing through the gable opening, especially at peak sunlight. I would rate it as a "quiet" fan but for sure, it is very much dependent on proper installation and proper air flow.

There is very little noise with my unit when the fan isn't running. And the only times so far that the fans have kicked in were when I had it hooked to my TV as an external display. Don't get me wrong, the fans are far from silent when they do kick in, but with fairly normal use, they usually don't.

If it's on low you can barely hear it, but on high it's kind of loud. It doesn't bother me, but if you're sensitive to noise, you might find it irritating. Great fan though. I've had it for a while and it's working perfect.

I just brought mine home and I did notice a slight fan noise when I had the sound turned way down. It was a little annoying, but something that I would get quickly used to. This set is so awesome I wouldn't even think about not buying it over such a nitpick.

Yes, my fan has some play but it feels like it is 'spring-loaded'; I thought it was intentional so it wouldn't go from pointing up to pointing down without a sturdy push into position. It feels to me as though the play is intentional; so that the movement of the fan blades wouldn't cause the entire thing to wobble.
