does it make noise at high RPM

The fans are good fans The ones I have purchased , which is 4 of them are not that load. The only issue I have is that the blade guards are cheaply made and do not always go together very well and I have had to zip tie them as a precaution. Hope this helps.

I installed 2 of them in my classroom. I prefer them on low since they are close to my desk. I depend on listening to help me monitor my students and class room behavior. However, if I had put them on the other side of the room or had not put them so close together, I would use a higher RPM.

Of course. At all speeds it makes noise but what you and I consider loud is different.

It is fairly loud on high. I use it in a workout room and have to turn up the TV volume. However, I rarely use it on high since it pushes a lot of air. The sound level on medium and low is not unreasonable.

I only notice when the hard drives spin up, but after that it's not noisy at all. (Small noises tend to bother me). It probably also depends on how loud the hard drive is.

It does make some noise, almost sounds like the Homedic shiatsu back massager. If you are using it in a quiet environment, you could hear the noise for sure.

I have mine mounted in my golf cart, so haven't heard any noises from it. However, when I first got it before it was mounted, I did not hear any sounds from its mechanism.

It does make a noise whether we go slowly or fast, and going fast you risk the plastic handle slapping back into the mounted part. It's not loud but it's noticeable.

Mine makes a very quiet high pitch sound, but you have to lean close to hear it.

This pump is louder than some. But it shouldn't get louder when it's mounted, sound like it may be loose and vibrating. I can hear the pump with the engine off, but barely.

It is loud I use it in my small engine repair shop and you can hear it over the radio and a 24inch high velocity fan

No , it isn't as good as i was hoping for the money.I installed it in a Kawasaki Teryx and the machine is fairly loud.

Depending on how high you set the speed, you get more or less whishing sounds; I suppose the low volume could be called a whine. To be expected when the thing is moving a volume of air.

Mine is noisier than I would expect at times, but nothing that has caused me too much alarm. I thought I heard it click a few times, but so far nothing reproducible or any overheating.

Mine doesn't make noise as I'm turning the gears, but if you hit the stops too hard, they'll make a "clunk." I'm not using this on a daily basis, but for the price, it is totally worth it. Works very smoothly in my opinion.

No.No.No.My fan makes an irritating noise on high speed that sounds like a howling wind. It is on now and I use # 2 selectionand its not doing that and I think the vibration comes from the "honeywell" button on the front.

I would say pretty high rpm. It doesn't put out full until about 1200rpms. Starts at around 900 before anything reads on my amp meter.

No. There is a low sound of the rollers along the track, and after 10,000+ strokes the main bushings will wear and will cause a dull "clunk". A call to customer service got me replacement bushings and corrected that. So, at it's worst ,the machine is not noisy.

No mam, it makes a very high pitched "ting ting" sound. It's really quite annoying but my little girl loves her so I deal. Haha

No it does not make any noise when using. All fold up area's are very snug when fitted together. I love it being so compact. It easily fits in my oxygen carrier case when not needed.
