My Winix doesn't have a constant fan hum - it sounds choppy. Is this normal?

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.

At low speeds it backs off than goes again if thats what you mean by choppy!

I've had mine for a couple months now, and its really quiet. If I were you, I'd return it.

Mine doesn't make a sound. Might be something wrong with the fan or something. Luckily, your WD has a 3 year warranty when you purchase it. You can either talk to your seller, or call customer service of WD since your WD has 3 year warranty with them...

This is a very high quality, quiet unit but you can hear the fan running at times. We actually have it in our pantry, so, we don't notice it, but I believe if you had it in a small kitchen, you would hear a low hum.

Hi, Michael. I can't tell, because my other 5 case fans hide it. I can tell you this: the overall noise of the whole system is pretty low. To illustrate this, I had to turn off the air conditioner to notice it. So, the card's fan contribution to noise must be next to nothing. I hope it's useful.

My unit does not make a loud buzzing sound but does have a slight humming sound from fan operating similar to a computer. Call tech support, they are awesome

This sounds like a defect. My unit is very stable and in normal use has been extremely quiet. Maybe yous has been damaged during shipment?

The fan doesn't make much noise. Depending on the temperature setting, the fan makes a low "quite" hum.

Not exactly in that condition but yes I have. For example when running a game but just in specific parts of the game like in the menu or something. I think the buzzing comes from the fans but not really sure.

It can make a very noticeable whine at full speed, which is 7000+ RPM. The can be set to only run on full at a temperature you set in BIOS though and can even limit the top speed as a percentage.

Sometimes this problem can be fixed by switching two blades opposite each other. My fan only makes a slight humming sound on low speed which is normal and does not wobble. The only other suggestion I have for you is to make sure all the screws are tight. If they are not, this could be the solution to your problem.Hope this helps!

Mine was pretty quiet most of the time. On startup the cpu fan would be a bit loud but it would quiet down again after a few seconds. I had it for two years, never annoyed me. I had the core i5 3330, gtx 660.

Mine works well, fans are very loud. They sent me replacements haven't installed yet...

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

I am running sli gtx770's and there is absolutely no noise. Also have not heard any type of coil whine and cannot tell when the fan is on unless I am looking at it through the bottom of my case.

Not noisy..but fan cuts off and on every 30 seconds.. does anyone know if this is normal? Only had for 2 months.. It has always done this.

Hello Debby, The short answer to that is no, I have had two of these PW3500s and apart from the cooling fan which is very quite they make no noise, even on full load. John.
