Is the fan supposed to make a high-pitched humming noise? It's really annoying.

We returned the fan a few days after receiving it because it was not what we expected. So sorry.

Ours is quiet. You can hear it but it sounds like a the fan that is built into our laptop. I wouldn't call it high pitch... that would be annoying.

Absolutely not! Mine is so quiet that sometimes I think it's stopped working. I have to bend down to hear it. Send it back.

Mine does make a very slight fan sound. Only noticeable if it is very quiet.

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.

No, It's not normal. It's probably 60 (Hz) hum. Try reversing you AC plug, that should fix the problem 90% of the time. If that doesn't work try grounding the case.

Define "really loud." Mine makes a noticeable noise throughout its entire on-cycle, but it is slightly louder on start-up. If I had to compare the running noise, though, I'd say slightly above desktop fan and slightly below window fan. It's not "whisper-quiet," that's for sure. But, the 'white noise' effect is somewhat soothing, I find. That's just me, though. I hope this helps!

Yes. Also this desktop has a problem of making a loud humming noise, check with other reviewers, this seems to be a common occurrence.

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!

I guess it is all relative .. Mine does make a hum... If our room was perfectly quite it would be annoying , but we have a central air fan , window ac , table fan going so it gets drowned out

I have had the biocube 14 running in my living room for almost 2 years now and I don't think i have ever noticed the sound of the fan. It is possible yours is rattling in place or you have a faulty fan? If it is actually loud I would contact the manufacturer.

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.

Mine does not hum, I use it as an automatic transfer switch in the living room, it's been on 24 hrs a day for a month with zero noise. I would return it and try another one.

It sounds like a low humming. My son uses it every night, all night since I purchased it and still works great, almost a year now since he's had it

No. I run mine (we have two) on a low speed and I only have a low hum from the fan.

Mine does this too, I was told that the fan is turning on and for some reason it is surging. It only does this when in standby mode, does yours do it when in use as well or just stand by?

it has a loud hum . I grounded the units directly to the Case of the Computer. It reduced the hum significantly. I replaced both units just last week because these are pretty much junk in my opinion.

No, the fan is *always on* and while not loud, is a constant distraction (adding about 50 dB of noise). Really bad design, Drobo!

A constant low hum. I tune it out almost immediately. I've never had any office neighbors comment or complain on the noise. It's probably slightly louder than the occasional grinding noise my water heater/cooler makes.
