Question: Does it provide white noise-- at least make a low hum?
Document: Okay, so the fan does make noise, but there is a motor and a fan, so that shouldn't be all that surprising. The amount of noise is more pleasant than annoying in my low-walled cubicle. I'll take white noise over silence when I'm working. Great throughput of air, VERY solid construction, and has a classic and sophisticated design.I'm thinking of buying a second for my desk at home.
This is a perfect office/cubicle fan! Small, quiet and unobtrusive. I like to turn it on to cool off as well as to provide a slight white noise affect to mask the sound of me munching on crunchy snacks at my desk.
I bought this fan to provide some white noise in my daughter's room. It was a bit smaller than I originally thought but that was fine. I plugged it in and all I heard was metal rubbing on metal somewhere. All I could think was that it was either annoying or a fire hazard, so it's in the garbage, lesson learned. You could see the wire nut inside the housing connecting 2 wires together. Not a great purchase
We've been carrying two small fans during our travels so that we can generate some air movement and white noise in hotel rooms and on cruise ships. The brand we had been using was made of plastic and has optional batteries. Nice, but the lifepsan of the fans is about 4 weeks of running every night. Then they all fail. Every one of them.Then we bought two of the Lakewood units that run on 110V A/C and have low current draw (we use a converter when abroad).
(like for the laptop)  If one or both of the fans actually DIES on me, I'll update this review. Otherwise assume the fans are both working great, even if several years have passed from the original posting of this review!LAST:  if neither fans die for at least a year with them running for SO MANY HOURS I will definitely upgrade the star count. But for now, starting to make noise in under six weeks, I think the "qualified" 2.5 stars is fair, right?
The fan is quite small, which was what I was looking for. It only makes a low hum, so it doesn't startle my hamster, and it's pretty powerful for such a small fan.
I bought this so my daughter could have a mini fan in her room to circulate air at night. This fan power is so low it barely provides any kind of air circulation. Its built rugged in construction but does not do the job of a fan. The cheaper built plastic ones provide much more circulation so I would look at buying one of those over this. This fan two speeds... off and on.
Buyers beware. Make sure you give yourself enough time to look around before buying this. I paid like $20 for this fan after freight which I purchased without really paying attention to the size of the unit. Well built, but for what it is, is way overpriced. I found this same fan in local stores for as low as $6.99Rip off stay away from this!! !
This is a great fan if your looking for a quiet desk fan. I wanted this in my bedroom for some white noise and it was too quiet.
Better quality than most, really good air flow, not loud but does offer some white noise. I have 3 now, 2 for my desks at work and 1 for home.
Answer: If you can get a good one, maybe.  But I've had a few of these, and they start to sound pretty awful.  The screws in the back don't stay tight and so they rattle.  I keep this fan on for white noise and cooling while I sleep, and the noise is difficult to sleep with sometimes.  It drives my husband nuts.
