Is unwanted noise from the mechanical motor/fan normal? The whining/rattling of the motor/fan is just as loud as the whoosing.

Seems to be the case. I was equally as disappointed with the extreme noise of the motor/fan.

No, it should never rattle! I think it depends as to whether you can hear a SMALL background whine or not. Mine is fine on the low speed, but has a very high-pitched background whine on the high speed. My husband can't hear it, but I can't stand it! Is yours still under warranty? Sounds like they should exchange it.

Probably not what you are asking about however, I had a fan problem with mine but not right away. After 5 days of ownership, I carried around my N120 and the following day the fan was making a rattling noise. The fan blade was obviously hitting something (similar to a stick hitting bicycle spokes). It appears there was something lose that decided to interfere with the fan blades. It would go away once it is powered down, it would also change volume if you move the computer around. Otherwise, the fan is quiet and normal, no vibration.

For me, it is just a normal sound of a running motor. I guess it just depends upon your sensitivity to sound.

No. It sounds as if you have an installation problem. I have a remote on this fan and it works fine. There is no unwelcome noise.

My experience with the Cool Attic fan was early on, also. Vibration had evidently loosened the two bolts at each end of the two motor brackets connecting the unit to the fan shroud. This allowed the fan blades to move towards the shroud to scrape (not a squeal, at least to me :))) it. I braced the brackets the opposite direction, tightened the four bracket bolts, and that was helpful. I may tighten the drive belt a bit because it cycles through a vibration occasionally and rubs the bracket-not critical or very noisy. "Squealing" suggest to me a belt noise, too. Maybe needs tightening a bit? My experience with the Cool Attic fan was early on, also.

For the most part, yes. There is a very faint hum of the motor and a bit of a trickle. I actually had to go turn one on to see if it made noise as it is not something intrusive at all. I have three of them in our house.

It makes a gentle whirring type noise - really the motor running. It didn't bother me though.

Did anyone read the manual? The fan is not a defect -- it expressly says on page 47 of the XBR4 manual in the troubleshooting section... "Condition: There is a whirring noise, Explanation: This is the sound of the internal fans of the TV. It is not a malfunction."

Yes that rattling is unusual and probably means the bearing are going bad...sorry to tell you that?

I have a unit which makes a noise like a normal fan would make. It does not make loud unexpected noise. There is a compressor unit in it like the one freeze and that has its own noise Apart from that I am not sure what kind of noise you are getting. Thanks

Noise is different to each person; however I find it to have a normal motor sound which is not that loud. I run mine in an enclosed garage, checking on it periodically.

Yes- It's probably normal not a defect. I've had similar appliances in the past and they all make a hum.

I wouldn't say this electric is noiseless but it is less noisy. The noise of a whining electric motor is how I'd describe the sound.

Mine has never made any rattling noise. I do not think it is normal. I would have it checked out.

Absolutely! After I installed mine there was a severe vibration when it was running. I called the manufacture and they had a local repairman out in 2 days and they discovered that the fan had gotten slightly bent during shipping so they ordered a new fan (and motor just to be sure) and installed them at no charge to me. Has been working great since.

After moving the purifier several times while vacuuming, mine has also developed a louder whirring noise. It is obvious at all levels. Level one used to be very quiet, an almost unnoticeable hum, but now it sounds like the motor is grinding and working overtime. As it's been less than a year, maybe less than half a year, I am planning on speaking to the manufacturer about it.

The motor is not loud at all. I've not cleaned the motor itself, I just rinse everything out every week. The sound of the water trickling is obvious but not offensive.
